Over the past century, the world has turned what used to be one of the planet’s most bountiful resources into an overexploited possession. Fish populations worldwide are becoming threatened by the growing demand for fish products. This occurrence is largely due to the world’s growing population and increased standards of living. It is estimated that one out of every five people depend on seafood as a main source of protein in their diet (Richard). Furthermore, countless regions and even entire countries rely on fishing operations to sustain their communities. The countess other world issues however, that are tied in with fisheries depletion are not the root causes for concern. The cause for concern lies within commercial and factory fishing, and the lack of global concern for a sustainable future. The effects of mass fishing have already devastated fish populations such as the Atlantic Cod, and has displayed devastating effects on marine biomes. Growing tastes for specific species of fish has also contributed to the repulsive amounts of bycatch caught, killed and released into the sea. The root causes of this global threat lie within man’s greed, not man’s need. Due to the tremendous negative impacts faced by global fish populations, fisheries sustainability is one of the most significant issues of the twenty-first century. The core threats originate in the growing and highly competitive commercial markets, the unsustainable methods of fishing, and the lack of political will to tackle illegal and irresponsible operations. The global consequences of fisheries depletion are endless, and the ripple effect is truly devastating. The western world is at most times detached from the hardships in foreign nations, but when it comes to fisheries, it is directly affected and part of the problem. Oceans house amazing and vast amounts of resources, and it is every nation’s right to take their fair share. But with rights come responsibilities, and in an environment as fragile as our world oceans, it takes all but one source of abuse to take down entire ecosystems and wipe out species. The crisis that has been occurring in our oceans over the past century is an issue often ignored in the media. It is an issue that takes a back seat to concerns humans have with things they can directly see or witness. Due to this disturbing ignorance, the problems have grown and are now able to be seen on a shocking scale, spreading their effects on both the natural and economic world.
A Brief History of World Fisheries
There was in fact a time when the world’s fisheries were perfectly sustainable. It was a time when populations thrived and lived within their natural environments in harmony. As shocking as this may be, this time was just a few centuries ago, and in the past century situations gotten even worse. In a mere one hundred years, man has turned what has thrived for millions of years into a threatened resource (Skerry, 34). In 1497, John Cabot sailed from Europe across the Atlantic Ocean. He arrived in North America, to what he called “New Founde Land” and discovered the bounty of the native seas (Canada, 3). At this time, great explorers and sailors would report on the amazing amounts of fish in the oceans; oceans which had never been fished before (see Appendix 1.1). As John Cabot reported, fish could be caught by simply dropping a net into the water, and hoisting up your catch (Ibid). Skill was not needed for catching this rich resource off the coasts of North America, and due to this find, by 1550, 400 ships per season would make the trip to fish the enormous supply of fish such as cod and Halibut (Ibid). These however, were the days without the massive amounts of technology invested into huge fishing industries, but come the 1900’s fisheries were in trouble.
As with the industrial and technological revolutions in society, the fishing industry saw its own time of dramatic change and expansion. Operations became more productive, and growing technology ensured a growing catch size. Between 1950 and 1989, the fishing industries saw such great advancement that the world catch went from 67 million tons per year, to 89 million tons. The rapidly increasing global catch sizes meant one thing to industries, and that was more profit. Newly acquired tastes for certain species led to over-harvesting in many fisheries, and population groups were fished relentlessly until the vessels had to move due to declining catch. In Brief, the world’s fisheries were becoming unsustainable, and the rate at which they were being caught was, and still is, much higher than that at which they can reproduce.
The Boom and Bust: The Reasons Behind Depletion
People often don’t view the world oceans as a delicate system. It is commonly viewed as a dangerous expanse of our world, and one with endless resources. Unfortunately, just like on land, our world oceans have been polluted and abused so badly that populations are on a sharp decline, and the ocean environment is being destroyed. It is estimated that many large fish species such as the shark and Blue Fin Tuna, have seen up to 90% depletion in their populations since 1900 (Sharkwater). However, it is not only the large species that face depletion and deserve attention. The world needs to focus on the foundations of the aquatic food chain, and how every link plays an important role in world oceans.
When the base of a food chain is disturbed, everything else above it is affected.
Plankton and ocean plant life is at the base of this food chain, and it is starting to disappear. This can be tied in with many other world issues as well, such as global warming, waste disposal and animal rights. Due to the damaged ozone layer, ultraviolet radiation is harming the microscopic organisms in world oceans. This radiation is also affecting juvenile fish species (Canada). According to the Scripps Institute
of Oceanography in California, “The population of Zooplankton in the waters off the coast of Southern California has declined by 70% in the last 42 years” (Ibid). This is most unfortunate news for both the fisheries, as well as the fishing industry. It is generally seen that where there is more plankton, there are more fish, and the most populated waters are mainly along coastlines where plankton is abundant (see Appendix 2.1). One major problem with waste disposal is that it affects fisheries in their most vulnerable environments. Disposal is usually along coastlines or in rivers leading out to sea. These just happen to be the locations where fish populations are most abundant, and offspring are commonly born. Due to human development, waters along these regions are getting cloudier. Erosion, construction, pollution and fishing techniques cause the water to become gloomy with kicked up mud and other debris (Ibid). This blocks the sunlight that countless ocean plants use for photosynthesis providing our world with oxygen. In fact, ocean plants provide 70% of the oxygen in our atmosphere (Sharkwater).
Further destructions comes with how fishing industries conduct their operations. A negative trend has emerged know as the boom and bust, and regardless of how many times this has happened, fishing industries persist in using the same destructive methods. It has occurred so often, that analysts divide it up into four stages. First we see the discovery, when fisherman discover a new abundant population of fish species in an area not previously explored. As the word spreads, intense exploration of the area begins and commercial fisheries are given large catch sizes due to high population, resulting in high profit (Berrill, 4). Due to the good times and extra profit, the second stage begins to unfold known as the expansion. It is like any other business; the industries improve their operations and technology, and begin fishing with a much higher intensity thanks to their abundant income (Ibid). Following the massive expansion phase comes depletion of the fish populations in that area, or even as an entire species. As the fishing industries try to expand to maintain their large catch sizes, they overextend the use of the fisheries, and as a result, lose money. Their costly operations rely on high catch sizes, but when the fisheries enter population depletion and catch sizes are lower, they can no longer afford such costly operations (Ibid). The final stage of this series, and the most unfortunate, is the collapse of the fishery. This is also followed by a probable debt or bankruptcy to the fishing industry. In many cases, the fishery has been so badly damaged, it has to be shut down, and many fishermen go unemployed (Ibid).
The Victims of the Boom and Bust
There are countless cases to demonstrate the boom and bust cycle. We in Canada often hear most about the Atlantic cod fishery. The first immigrants to the East Coast, coming from England and Ireland, were completely dependant on Cod. Each summer, the fish would swim to the coastal areas and the fisherman would catch them with line and hooks. It was then salted, dried, and stored to support the growing human population (Canada, 8). Come the mid-1800’s, the cod fisheries began a massive expansion. Many nations began to realize the opportunity this bountiful source of protein provided, and it was not long until large numbers of fishing vessels sailed off the shores of the East Coast (Ibid). In March of 1954, a technological advancement came out of Scotland that would forever change world fishing industries. Scotland introduced the Fairtry, the first factory freezer trawler with nets that could be hauled over its stern (better for all weather conditions). It was equipped with automatic filleting machines and cold storage devices (Ibid). Electronic Equipment and location devices came about, allowing fishermen to literally see the cod, and drop their nets right on top of them This brought the catch from 300,000 tones per year, to 775,000 by the 1980’s (Ibid). Despite the warning of populations declining, most fishing industries ignored this information and were even encouraged by the government with subsidies (Ibid, 10). As more nations got involved and technology increased, the cod population decreased exponentially. From 1990-1994, the Atlantic cod stock off the east coast of Canada fell 95% (See Appendix 3.1).
Another fine example can be seen with the California sardine. This fishery use to be rich and abundant just as any other, but fame led to its downfall. Sardines live in large schools, making them a fishermen’s dream. These schools were as large as a few hundred million fish spanning a diameter of eight kilometers (Berrill, 6). Upon their decline, the sardines still maintained their large schools, just less of them, making the ease of capture relatively the same (Ibid). Their demand grew in global markets, and the fishery expanded far beyond its sustainable limit. The fishery ultimately saw its peak and then sharp collapse in 1935 (See Appendix 3.2). Whenever one fishery collapses, the fishing industry doesn’t just shut down and die, they move on to the next available resource and start the cycle all over again. After the collapse of the California sardine the Peruvian anchoveta was next on the list. This is no doubt one of the most devastating examples of the boom and bust. The anchoveta was a species untouched until the 1950’s (Berrill, 8). It entered the boom phase as the global demand for fish meal products was on the rise, and the profit of fishing operations was increasing dramatically (Ibid). Peru ended up buying the California canneries and fishing vessels once used for sardines and dominated the world market (Ibid). The anchoveta fishery off the coasts of Peru grew so drastically, that it accounted for 25% of the world catch by the mid 1960’s (Ibid, 9). A short while later, in 1970, the fishery hit its peak, and the unsustainable practice collapsed closing down the fishery (Ibid). (See Appendix 3.2)
Bycatch and the Destructive Methods of Fishing
The root causes of the damage done to marine ecosystems and countless fisheries is due to the abusive and unsustainable methods of fishing. The main three categories of fishing techniques are impounding, entangling, or hook and line (Commercial Fishing, 107). The method of impounding involves surrounding schools of fish with long nets. One example of this method is the purse seine. The second method, the method of entangling can be seen by the use of gill nets. These are long nets that remain suspended in the water where schools of fish are known to swim by. As the fish pass through, they get tangled in the net’s fibers and holes. These nets are so massive, that just one gill net can hold multiple thousand pounds of catch. To put this into perspective is the following quote from Michael Berrill’s book “The Plundered Seas”;
“Imagine a ship of 300 to 400 tonnes, with a crew of fifteen to twenty, able to stay at sea for one to two months, setting its nets one a day. The nets, called driftnets, come in five to ten sections, each 5 to 10 kilometers long. When set, the entire net is 25 to 55 kilometers long, hanging like an invisible curtain 10 to 15 meters below the sea surface.”
These nets obviously do not have a specific catch, and countless different unwanted species get tangled and die each year in their grasp. Hook and line methods, also known as long lining, is one of the other methods used that can be just as damaging. It consists of a long fishing line, often miles line with hundreds or thousands of hooks. The hooks often remain suspended in the water, as many long lines are attached to floats on the surface (Ibid). Arguably the most destructive method of fishing is bottom trawling. It involves towing large nets behind a fishing vessel, which drag across the ocean floor to collect catch. These nets are held opened by giant steel structured tied to each end that dig into the sea bed keeping the net flush with the ocean floor (Skerry, 39). It would be like randomly driving a giant bull-dozer through the city. Bottom trawling causes massive habitat destruction, including coral shattering, and seaweed removal (Ibid). (To see visual examples of these methods of fishing, see Appendix 4.1)
Large fishing operations are not as advanced and specific as some people would think. Although their technology is impressive, and their catch sizes are high, many people don’t stop to think what is actually being used, or discarded. Bycatch is a major threat to the world’s marine ecosystems, affecting both marine animals as well as plant species and crucial habitat. This issue is partly the cause of populations decline in literally all large ocean predators, which have seen 90% depletion in the past fifty years (Halweil, 70). Countless vessels out for a specific species, will often catch large amounts of fish that either do not meet the proper specifications or market value, or are not even the intended species (Berrill, 62-72). This is a major problem in almost all commercial fishing methods, but a particular problem with long lining and trawling which may account for up to 50% of all bycatch (Skerry, 39). European and Asian markets have been some of the worst for this problem, and situations around the world have yet to see any substantial recovery. The World wildlife Federation noted in 2006 that up to 80% of catches in the North Sea fisheries are thrown overboard dead, or to die. They also stated that for every swordfish illegally caught off the coasts of Morocco, two sharks are killed in the process ("Commercial Fishing Devastates Europe's Oceans - WWF"). Bycatch has never been by any means a small issue. It is estimated that 30% of the fish caught around the world are thrown back, which accounts for billions of fish per year (Ibid). In many cases, fishermen will haul in large nets full of fish, none of which they will keep. Some fisheries however, are worse than others, and growing competition in world markets are further intensifying the situation, leading to more bycatch (Skerry,53). In the more recent years, West Africa’s fisheries are heading in the same direction as Europe’s, and the large amounts of bycatch which could be used as much needed food for Africa is thrown back, as it is of little value to larger world markets (Ibid). (See Appendix 4.2 for examples and visuals of bycatch)
Long lining operations around the world are notorious for catching sharks and other large fish species. In many cases, the sharks are only used for their fins and then thrown overboard, dead or alive (Sharkwater). This has become a massive problem due to the growing markets in Asia, particularly China, where the fins can be sold for four hundred dollars per kilogram (Ibid). Worldwide, it is estimated that 40 million sharks per year are killed just for their fins (Skerry, 33). Bycatch its not only a problem with fish species, but tons of other coastal and ocean wildlife, and in some cases, it is not alive at all. As displayed in appendix 4.2, everything from ocean birds, to turtles, to corals can get caught in the process. While long lining, baited hooks also catch the eye of sea turtle and birds looking for a meal. In many cases, these animals will die as they can not free themselves from the trap (Sharkwater). Bottom trawling presents an all new breed of bycatch, and that is large amounts of structure picked up from the ocean floor. The large steel weights that hold down their nets shatter corals, rip up plant life and kick up mud clouds so massive, they can be seen by satellite (Refer back to appendix 4.2 – bottom trawling). These trawling operations are common when fishing for shrimp and prawns, which are one of the worst fisheries in terms of bycatch (Berrill, 63). For every one million tones of shrimp caught, there is five million tons of bycatch (Ibid). Crab fisheries are also among the worst, with over half of the catch being thrown back (Ibid). (see chart in appendix 4.3)
Global Markets and the effects of the First World Appetite
In Canada, the fishing and oceans industry has an output value of about $22.7 billion dollars. The industry employs 152,000 Canadians with a total commercial catch of over 1 million tons (DFO). The amount of fishing vessels registered in Canada alone totaled 23,244 in 2004. As with countless other nations, many people residing in coastal areas, and large sectors of the economy depend on ocean resources (Ibid). Many nations however, with some of the highest catch sizes (and in some cases over double the Canadian catch – see appendix 5.1) are newly industrialized and developing nations (Berrill, 26). The newly industrialized nations mostly depend on smaller scale fishing operations, and remain relatively close to their coastline compared to the wealthier operations from the developed world. Recently however, due to growing economies and more productive fishing operations, countries like South Korea, and more recently yet, China, have started to fish more distant waters (Ibid). Many of the fisheries along the north and south west Pacific are some of the most abundant in the world (Refer back to appendix 2.1), and only recently have many developing and newly industrialized nation been able to fish them (Bocknek, 12). Between the industrialized world and a growing industry in the developing worlds, the annual global production of fish reached 156.3 million tons by the year 2000 (see appendix 5.3).
The western world’s tastes in present day fisheries have dominated the global markets, causing massive destruction. However, more recently it has been the Asian markets with their growing demand that has driven populations to their demise. Between the developed world’s ‘sophisticated’ tastes and the Asian markets demand for shark fin and other wasteful products, many fisheries are being terribly exploited. Boris Worm, the lead researcher at Dalhousie University in Halifax states that one third of seafood species in our oceans have collapsed to this day. He also warms that “If this trend continues, if we don’t change the way we are managing ocean ecosystems, this trend projects that 100% of species will collapse by the year 2048 or around that” (Ommer). The problem with increased demand and higher price tags on fish products does not only harm fish populations, but also the people of developing countries. For example, fisheries off the coasts of Africa are exploited by world markets, leaving local fishermen with declining catch sizes, and depriving locals of the much needed source of protein (Skerry, 41). In many cases, only the carcasses of fish are left to sell in local African markets, as the fillets are sold to higher bidders elsewhere in the world (see appendix 5.4). In order to make a living, many African fishermen can not afford to keep fish that is of no value to global markets, even if it could mean feeding thousands of starving locals. As seen in appendix 4.1, Senegalese fishermen, hoping to catch the sought after shrimp and sole, haul in an ‘empty’ yet full net, wasting valuable protein for Africa. Many third world nations are left with only what they can afford to keep, contributing to hunger and violence. With highly prized delicacies like shark fin selling for top dollar in Asian markets, violence and human exploitation is inevitable. Massive black markets have opened up for such products, and corrupt governments work along with illegal fishing operations to make money (Sharkwater). Countless ships constantly fish illegally for shark and other prized possessions like sturgeon for caviar and don’t get caught. Even when they do get caught however, it is often hard to stop them because of ties with either corrupt government or with gunboats. Many fisheries are so valuable and attractive to poor nations, that militias will even get involved in the process (Ibid).
The Rough Waters Ahead: What Must be Done to Protect World Fisheries
With 0.01% of the oceans closed to fishing, and total collapse of all fisheries in the foreseeable future, protection of world oceans is one of the most contemporary and concerning global concerns (Skerry, 78). After the technological revolution took its toll on global fisheries, researchers began to see the astronomical damage that industries were inflicting on the world oceans. Unfortunately, by the time many boom and bust cycles are caught in the act, they are already in the stage of depletion and exploitation, with no real governing body to put a soon enough stop on the operations. Many markets are uncontrollable as they operate on a global scale with national boundaries prohibiting intervention by protection agencies found in much of the developed world. Managing our world oceans is not as simple as monitoring one or two species in a few particular areas. Countless ocean environments are interconnected forming a massive ecosystem, every part affecting one another in astonishing ways. When one link of this global chain is removed or weakened, it affects the sustainability of the entire system. This is why it is up to every nation to do its part to help restore the world’s fisheries. David Suzuki, one of the world’s most renowned environmentalists, has laid out ten principles to managing our fisheries in the future (Suzuki). First off, as stated above, one must look at and manage the entire ecosystem, not individual stocks. Secondly, the world needs to adopt a more precautionary approach to the management of our fisheries. It is better to err on the side of caution than to risk irreversible damage as seen in the past. Another major shift that the world must see is giving the say to people who are for the best interests of the fisheries, not profit. If the world continues to let the industry and global market demand decide, the unfortunate forecasts of future fisheries are likely to come true. The world must also decrease its wasteful capacity, and plan sustainable fishing methods that work around natural fluctuation in fishery populations. If there is a lack of understanding or regulation regarding natural cycles, industry will continue to fish when species are in vulnerable positions. Biodiversity is another concern that must be dealt with to ensure a healthy and balanced future in world oceans. Every species plays an important role in the balance of ocean ecosystems. Every species is an important link to this global chain, and crucial to the survival of many other species. The habitat of these species also need top priority if overall health of the environment is to exist. Trawling operations threaten this very element, and until operations respect the fish habitat, they will not be able to respect the fish species. In regards to bycatch, and the needs to reduce it, the reasons are self explanatory. The oceans can not afford the millions of tons of discarded species, and furthermore, the world should not stand for these immoral practices. The countless fish caught as bycatch all play a significant role in the ocean ecosystem. When species like shark, and even fish lower on the food chain are caught by the millions, it disrupts global balance and throws off the entire food web. Finally, the world markets and consumers must be educated. The issues regarding fisheries sustainability must come out of the dark, and be shared with the world to help consumers make contentious decisions. Until people realize how the food they eat got on their plate, and the impact that it had on the world, demand will allow the destructive methods to continue (Ibid). (For a list of sustainable seafood products, see appendix 6.1 regarding low to high risk species.)
The irresponsible practices in today’s fishing scene not only exploit countless species of marine wildlife, but also millions of people in the developing world. It is my belief this problem will one day be solved, but it will take a global effort. If we see this issue as merely a low priority concern, and never give it the global recognition it needs to be solved, we will not make any headway. The world’s view towards many ocean species also disadvantages them in terms of protection, because species like the shark are not as cute and cuddly as pandas or monkeys. Why does everybody sit still while millions of sharks are slaughtered for their fins, and thrown back to die an agonizing death? The world must understand all creatures deserve equal respect, and it can not be justified to let our oceans die right before our very eyes. I know what harm we are causing today, and I know that future generations will look back at the irreversible harm we have caused and wonder why we chose to ignore the problems. Yet we should never forget that the gloomy forecasts put out by experts are only true if we continue our current patterns; only true, if we let them happen. Perhaps the most significant legislative changes will have to come from environmental protection agencies and the fishing industry itself, but there is one thing that trumps these two elements combined; the consumer. In the end, it is the consumer that decides what the industries fish for; it is the consumer, that decides what populations are being threatened or saved, and it is the consumer, who can save our world’s most vast and incredible resource, our world fisheries.

There was in fact a time when the world’s fisheries were perfectly sustainable. It was a time when populations thrived and lived within their natural environments in harmony. As shocking as this may be, this time was just a few centuries ago, and in the past century situations gotten even worse.

Bycatch and the Destructive Methods of Fishing
The root causes of the damage done to marine ecosystems and countless fisheries is due to the abusive and unsustainable methods of fishing. The main three categories of fishing techniques are impounding, entangling, or hook and line (Commercial Fishing, 107). The method of impounding involves surrounding schools of fish with long nets.

These are long nets that remain suspended in the water where schools of fish are known to swim by. As the fish pass through, they get tangled in the net’s fibers and holes. These nets are so massive, that just one gill net can hold multiple thousand pounds of catch. To put this into perspective is the following quote from Michael Berrill’s book “The Plundered Seas”;
“Imagine a ship of 300 to 400 tonnes, with a crew of fifteen to twenty, able to stay at sea for one to two months, setting its nets one a day. The nets, called driftnets, come in five to ten sections, each 5 to 10 kilometers long. When set, the entire net is 25 to 55 kilometers long, hanging like an invisible curtain 10 to 15 meters below the sea surface.”
These nets obviously do not have a specific catch, and countless different unwanted species get tangled and die each year in their grasp. Hook and line methods, also known as long lining, is one of the other methods used that can be just as damaging. It consists of a long fishing line, often miles line with hundreds or thousands of hooks. The hooks often remain suspended in the water, as many long lines are attached to floats on the surface (Ibid). Arguably the most destructive method of fishing is bottom trawling. It involves towing large nets behind a fishing vessel, which drag across the ocean floor to collect catch. These nets are held opened by giant steel structured tied to each end that dig into the sea bed keeping the net flush with the ocean floor (Skerry, 39). It would be like randomly driving a giant bull-dozer through the city. Bottom trawling causes massive habitat destruction, including coral shattering, and seaweed removal (Ibid). (To see visual examples of these methods of fishing, see Appendix 4.1)
Large fishing operations are not as advanced and specific as some people would think. Although their technology is impressive, and their catch sizes are high, many people don’t stop to think what is actually being used, or discarded. Bycatch is a major threat to the world’s marine ecosystems, affecting both marine animals as well as plant species and crucial habitat. This issue is partly the cause of populations decline in literally all large ocean predators, which have seen 90% depletion in the past fifty years (Halweil, 70). Countless vessels out for a specific species, will often catch large amounts of fish that either do not meet the proper specifications or market value, or are not even the intended species (Berrill, 62-72). This is a major problem in almost all commercial fishing methods, but a particular problem with long lining and trawling which may account for up to 50% of all bycatch (Skerry, 39). European and Asian markets have been some of the worst for this problem, and situations around the world have yet to see any substantial recovery. The World wildlife Federation noted in 2006 that up to 80% of catches in the North Sea fisheries are thrown overboard dead, or to die. They also stated that for every swordfish illegally caught off the coasts of Morocco, two sharks are killed in the process ("Commercial Fishing Devastates Europe's Oceans - WWF"). Bycatch has never been by any means a small issue. It is estimated that 30% of the fish caught around the world are thrown back, which accounts for billions of fish per year (Ibid). In many cases, fishermen will haul in large nets full of fish, none of which they will keep. Some fisheries however, are worse than others, and growing competition in world markets are further intensifying the situation, leading to more bycatch (Skerry,53). In the more recent years, West Africa’s fisheries are heading in the same direction as Europe’s, and the large amounts of bycatch which could be used as much needed food for Africa is thrown back, as it is of little value to larger world markets (Ibid). (See Appendix 4.2 for examples and visuals of bycatch)
Long lining operations around the world are notorious for catching sharks and other large fish species. In many cases, the sharks are only used for their fins and then thrown overboard, dead or alive (Sharkwater). This has become a massive problem due to the growing markets in Asia, particularly China, where the fins can be sold for four hundred dollars per kilogram (Ibid). Worldwide, it is estimated that 40 million sharks per year are killed just for their fins (Skerry, 33). Bycatch its not only a problem with fish species, but tons of other coastal and ocean wildlife, and in some cases, it is not alive at all. As displayed in appendix 4.2, everything from ocean birds, to turtles, to corals can get caught in the process. While long lining, baited hooks also catch the eye of sea turtle and birds looking for a meal. In many cases, these animals will die as they can not free themselves from the trap (Sharkwater). Bottom trawling presents an all new breed of bycatch, and that is large amounts of structure picked up from the ocean floor. The large steel weights that hold down their nets shatter corals, rip up plant life and kick up mud clouds so massive, they can be seen by satellite (Refer back to appendix 4.2 – bottom trawling). These trawling operations are common when fishing for shrimp and prawns, which are one of the worst fisheries in terms of bycatch (Berrill, 63). For every one million tones of shrimp caught, there is five million tons of bycatch (Ibid). Crab fisheries are also among the worst, with over half of the catch being thrown back (Ibid). (see chart in appendix 4.3)
Global Markets and the effects of the First World Appetite
In Canada, the fishing and oceans industry has an output value of about $22.7 billion dollars. The industry employs 152,000 Canadians with a total commercial catch of over 1 million tons (DFO). The amount of fishing vessels registered in Canada alone totaled 23,244 in 2004. As with countless other nations, many people residing in coastal areas, and large sectors of the economy depend on ocean resources (Ibid). Many nations however, with some of the highest catch sizes (and in some cases over double the Canadian catch – see appendix 5.1) are newly industrialized and developing nations (Berrill, 26). The newly industrialized nations mostly depend on smaller scale fishing operations, and remain relatively close to their coastline compared to the wealthier operations from the developed world. Recently however, due to growing economies and more productive fishing operations, countries like South Korea, and more recently yet, China, have started to fish more distant waters (Ibid). Many of the fisheries along the north and south west Pacific are some of the most abundant in the world (Refer back to appendix 2.1), and only recently have many developing and newly industrialized nation been able to fish them (Bocknek, 12). Between the industrialized world and a growing industry in the developing worlds, the annual global production of fish reached 156.3 million tons by the year 2000 (see appendix 5.3).
The western world’s tastes in present day fisheries have dominated the global markets, causing massive destruction. However, more recently it has been the Asian markets with their growing demand that has driven populations to their demise. Between the developed world’s ‘sophisticated’ tastes and the Asian markets demand for shark fin and other wasteful products, many fisheries are being terribly exploited. Boris Worm, the lead researcher at Dalhousie University in Halifax states that one third of seafood species in our oceans have collapsed to this day. He also warms that “If this trend continues, if we don’t change the way we are managing ocean ecosystems, this trend projects that 100% of species will collapse by the year 2048 or around that” (Ommer). The problem with increased demand and higher price tags on fish products does not only harm fish populations, but also the people of developing countries. For example, fisheries off the coasts of Africa are exploited by world markets, leaving local fishermen with declining catch sizes, and depriving locals of the much needed source of protein (Skerry, 41). In many cases, only the carcasses of fish are left to sell in local African markets, as the fillets are sold to higher bidders elsewhere in the world (see appendix 5.4). In order to make a living, many African fishermen can not afford to keep fish that is of no value to global markets, even if it could mean feeding thousands of starving locals. As seen in appendix 4.1, Senegalese fishermen, hoping to catch the sought after shrimp and sole, haul in an ‘empty’ yet full net, wasting valuable protein for Africa. Many third world nations are left with only what they can afford to keep, contributing to hunger and violence. With highly prized delicacies like shark fin selling for top dollar in Asian markets, violence and human exploitation is inevitable. Massive black markets have opened up for such products, and corrupt governments work along with illegal fishing operations to make money (Sharkwater). Countless ships constantly fish illegally for shark and other prized possessions like sturgeon for caviar and don’t get caught. Even when they do get caught however, it is often hard to stop them because of ties with either corrupt government or with gunboats. Many fisheries are so valuable and attractive to poor nations, that militias will even get involved in the process (Ibid).
The Rough Waters Ahead: What Must be Done to Protect World Fisheries
With 0.01% of the oceans closed to fishing, and total collapse of all fisheries in the foreseeable future, protection of world oceans is one of the most contemporary and concerning global concerns (Skerry, 78). After the technological revolution took its toll on global fisheries, researchers began to see the astronomical damage that industries were inflicting on the world oceans. Unfortunately, by the time many boom and bust cycles are caught in the act, they are already in the stage of depletion and exploitation, with no real governing body to put a soon enough stop on the operations. Many markets are uncontrollable as they operate on a global scale with national boundaries prohibiting intervention by protection agencies found in much of the developed world. Managing our world oceans is not as simple as monitoring one or two species in a few particular areas. Countless ocean environments are interconnected forming a massive ecosystem, every part affecting one another in astonishing ways. When one link of this global chain is removed or weakened, it affects the sustainability of the entire system. This is why it is up to every nation to do its part to help restore the world’s fisheries. David Suzuki, one of the world’s most renowned environmentalists, has laid out ten principles to managing our fisheries in the future (Suzuki). First off, as stated above, one must look at and manage the entire ecosystem, not individual stocks. Secondly, the world needs to adopt a more precautionary approach to the management of our fisheries. It is better to err on the side of caution than to risk irreversible damage as seen in the past. Another major shift that the world must see is giving the say to people who are for the best interests of the fisheries, not profit. If the world continues to let the industry and global market demand decide, the unfortunate forecasts of future fisheries are likely to come true. The world must also decrease its wasteful capacity, and plan sustainable fishing methods that work around natural fluctuation in fishery populations. If there is a lack of understanding or regulation regarding natural cycles, industry will continue to fish when species are in vulnerable positions. Biodiversity is another concern that must be dealt with to ensure a healthy and balanced future in world oceans. Every species plays an important role in the balance of ocean ecosystems. Every species is an important link to this global chain, and crucial to the survival of many other species. The habitat of these species also need top priority if overall health of the environment is to exist. Trawling operations threaten this very element, and until operations respect the fish habitat, they will not be able to respect the fish species. In regards to bycatch, and the needs to reduce it, the reasons are self explanatory. The oceans can not afford the millions of tons of discarded species, and furthermore, the world should not stand for these immoral practices. The countless fish caught as bycatch all play a significant role in the ocean ecosystem. When species like shark, and even fish lower on the food chain are caught by the millions, it disrupts global balance and throws off the entire food web. Finally, the world markets and consumers must be educated. The issues regarding fisheries sustainability must come out of the dark, and be shared with the world to help consumers make contentious decisions. Until people realize how the food they eat got on their plate, and the impact that it had on the world, demand will allow the destructive methods to continue (Ibid). (For a list of sustainable seafood products, see appendix 6.1 regarding low to high risk species.)
The irresponsible practices in today’s fishing scene not only exploit countless species of marine wildlife, but also millions of people in the developing world. It is my belief this problem will one day be solved, but it will take a global effort. If we see this issue as merely a low priority concern, and never give it the global recognition it needs to be solved, we will not make any headway. The world’s view towards many ocean species also disadvantages them in terms of protection, because species like the shark are not as cute and cuddly as pandas or monkeys. Why does everybody sit still while millions of sharks are slaughtered for their fins, and thrown back to die an agonizing death? The world must understand all creatures deserve equal respect, and it can not be justified to let our oceans die right before our very eyes. I know what harm we are causing today, and I know that future generations will look back at the irreversible harm we have caused and wonder why we chose to ignore the problems. Yet we should never forget that the gloomy forecasts put out by experts are only true if we continue our current patterns; only true, if we let them happen. Perhaps the most significant legislative changes will have to come from environmental protection agencies and the fishing industry itself, but there is one thing that trumps these two elements combined; the consumer. In the end, it is the consumer that decides what the industries fish for; it is the consumer, that decides what populations are being threatened or saved, and it is the consumer, who can save our world’s most vast and incredible resource, our world fisheries.
