The Bluefin tuna, Thunnus Thynnus, is a top predator of the oceans, and the most valuable fish in the world. David Attenborough once called it a “superfish”. Despite its Darwinian advantages commercial fisheries have exploited Bluefin for decades, and the population has fallen to an estimated 36% of its already depleted 1970 level1. Originally, fish were caught by rod and reel, one by one. During the 1980s commercial fisheries developed techniques, such as the use of long lines, drift nets and purse seines to catch thousands of these animals at a time. These techniques have obliterated the population of Bluefin in just a few decades. They also wreak havoc on the ocean killing millions of sea turtles, sharks, whales, dolphins- pretty much every living creature they come across. In 2007 the WWF warned of the imminent collapse of the Mediterranean population, in their article “Bluefin Tuna in Crisis”. However, this has not reduced the efforts of fisheries to catch these majestic creatures; with more boats chasing fewer and fewer fish, the species is being driven towards extinction. This common is being overused and could tragically disappear in the near future unless drastic changes are made. Both fishermen and consumers, as well as everyone who is affiliated with nature to some degree will be affected. The responsibility to prevent this tragedy is everyone’s, but business should lead the way in making commercial Bluefin fishing sustainable. Otherwise our planet will begin to look similar to Old MacDonald’s farm.
In his book Tuna, Richard Ellis, the indisputable champion of contemporary ocean chronicling, describes how bad the situation really is. “Hundreds of thousands of tons of bluefin- which translates to billions of fish- are ca...

... the profitability of commercial Bluefin vessels would fall, and firms would leave the market. This would reduce annual catch counts, allowing the population to stabilize and eventually rebuild. The reality is, however, that the story of Bluefin tuna is beginning to look a lot like that of Codfish, which is all but extinct. Bluefin tuna are on the endangered species list, and on the brink of extinction. Lobbying against regulations will keep it there as long as there is money to be made. Sadly, corporate greed and myopic ignorance will likely drive the majestic Bluefin out of existence.

In this entertaining, search into global fish hatcheries, New York Times writer Paul Greenberg investigates our historical connection with the ever changing ocean and the wild fish within it. In the beginning of the book Paul is telling his childhood fishing stories to his friends, that night Paul discovers that that four fish dominate the world’s seafood markets in which are salmon, tuna, cod, and bass. He tries to figure out why this is and the only logical answer he could come up with is that four epochal shifts caused theses wild fish population to diminish. History shows that four epochal shifts happen within fifteen years causing certain fish species populations to diminish. He discovers for each of the four fish why this happened to
In the past twenty years a large amount of bottlenose dolphin have been killed due to the tuna fishery. In the Eastern Pacific swim large schools of tuna, these shoals tend to be under herds of dolphins, for some unexplained reason. Because of this, fishermen can easily find schools of tuna. The tuna are being caught under purse seine nets, which encircles the shoals of tuna and then is pulled back on board the fishing vessel, catching both tuna and dolphin. Initially the mortality rate was 500,000 each year for dolphins alone. Although some efforts are made to encourage the dolphins to leave the net by backing down part of the net, which allows the dolphins to escape, there are still a large number of mortalities (Bryant). On the other hand, in the last few years there has been dramatic progress in stopping the fishing industries from using purse sine nets. It has been found that dolphins are in immediate danger of extinction if these fishing techniques don’t stop.
Overfishing may have some benefits to it, but does it out way the negatives? By fulfilling our demand we can wipe out our whole oceans! Not just the fish, but water mammals too. Sure it can create jobs, but as what cost? It can help bring up our economy, but at the same time it can bring it down with many fish companies closing down due to lack of profit. Fish is a great source of nutrients, but too much can kill you! In other words, fish can be both beneficial and harmful to not only humans, but everyone and everything surrounding fish. There are three things people can do to help with overfishing, the first thing is to be aware of what you are eating. Is the fish on the fear of extinction list? Also asking yourself is the fish you’re about to eat really the fish you intend to eat? Another thing to ask is, was it shipped over seas? If it was it doesn’t benefit anyone, it won’t help the economy or you. Many fish shipped from a long ways creates pollution and may have lost its nutrients value from the long voyage. One last thing to do is if you see a sewer with a sign leading to the ocean, try not to leave trash near it, or better yet don’t litter at all! All the litter left out on streets or near sewers can cause pollution in oceans, lakes, and rivers which is very harmful for marine life. You can still enjoy fish, but not at such a high demand as
Earth's oceans make up over 75% of the Earth as a whole. With that being said, it is vital to understand the significance on the contents of the oceans. Since fish and marine products make up a large portion of our diet, fishing practices need to be properly managed. In this essay, overfishing will be defined, its consequences will be revealed, and plans for proper fish distribution will be executed.
Rupert Murray’s The End of the Line focuses on the depletion of the oceans fisheries and the devastating effects it has already begun to have on ecosystems and less affluent populations. The film opens with a description of the tribulations of Newfoundland. Once possessing waters so populous with cod that one could “walk across their backs in the water,” improved technology and larger fishing vessels began to deplete the fish stocks. Despite placing a moratorium on fishing in 1992, the fisheries had already been depleted to the point of complete collapse. Similar processes are occurring around the world, as only .6% of the ocean is restricted to fishing vessels. According to the film, much of the ocean’s catch has declined by 90%; the continuation of current trends if continue, stocks will collapse by 2048.
For years corporations have been depleting the oceans of its wildlife for our benefit. However, one thing these corporations tend to not mention is the bycatch they encounter when catching fish for the purpose of consumption. The definition of bycatch “is the unintended capture of nontarget animals…”(Crowder and Murawski pg.1). Bycatch takes a negative toll on our ocean ecosystem that cannot be reversed.
Looking at Figure C, we can say more than 200,000 blue whales has been killed as results of overhunting. In 1966, the International Whaling Commission banned commercial whaling for blue whales, but illegal hunting still occurs (NOAA). While blue whales are no longer being threatened by overhunting, their population is drastically depleted. Like many other marine species, blue whales are being harm by many others factors today. This include collisions of ships, chemical pollution such as oil spills, and noise pollution from vessels (Eco). The population of blue whales is known to be around “10,000 to 25,000 ” (World Wild Life).
Overfishing refers to an act of fishing more than what the population can replace through normal reproduction (WWF, 2016). This was led by international government efforts to increase fishing capacity in the mid-20th century, which then led to the increase in availability and affordability of protein-rich foods. With this, profitable commercial fleets became aggressive, scouring the world’s oceans and developing sophisticated technologies to find and catch their targeted species. Thus, with a wide selection of fish species available at affordable prices, customers soon became used to them (Geographic, 2016).
Unfortunately, as Nixon points out, the slow deterioration of marine environments is not broadcasted because these gradual events will not “boost ratings on TV” (6). As the fish populations dwindle to point of extinction, minimal action is being taken to counteract overfishing and as Nixon suggests it is because the steady disappearance of fish isn’t broadcasted or highlighted as a major event that needs to be dealt with
There are many impacts that fishing and land animal farming have on the ocean, which are detrimental to ocean ecosystems as well as many other aspects of the environment. Overfishing, killing fish at a much quicker rate than the fish can repopulate, is one major problem. Three-fourths of the world’s fisheries are either fully exploited, overexploited, or depleted (Cowspiracy). Researchers have estimated an end of all viable fisheries by 2018 if the current trends of fishing continue (Mason). According to the Monterey Bay Seafood Watch, hundreds of thousands of animals die every year as bycatch, with one of the worst offenders being shrimp fisheries, catching up to six pounds of bycatch per pound of shrimp. Endangered species are also caught, including predators which are important in keeping the balance in ocean ecosystems (Smith). While many organizations such as the Monterey Bay Aquarium Seafood Watch recommend consumers to eat more “sustainable” fish, this will not stop the massive environmental impacts. Sustainable fishing for one does not account for the natural flux in the population of species of fish; what is considered a sustainable amount of fish to harvest one year may deplete the fishery in another year (Smith). Sustainable fish also are becoming even less sustainable as companies that label sustainable fish must find more For example, after Wal-Mart pledged to selling Marine Stewardship
With a coastline of over 202 000 km and over a fourth of the world’s freshwater resources, it is no wonder why Canada’s fishing industry is a huge part of its economy.1 Canada exports more than 75% of its fish to over 130 countries worldwide. Many of the 7 million people who reside on the coast depend on the ocean’s resources. In total, Canada’s entire fishing industry is worth around 5$ billion dollars a year, being one of the world’s most valuable. However, the coasts have not been treated by respect; overfishing, over consumption, and wasteful practices has deteriorated, not only the industry, but the ecosystems and fish populations. This is a huge global issue; the worldwide collapse of fisheries has been project for 2048. Slowly, as the trends continue, we will inevitably see many fish species start to disappear. In fact, the ill-treatment of species on the Canadian border has already devastated a large specie, the cod.
To fish or not to fish is a personal choice. The fact that the oceans are being overfished is a growing concern for individuals, organizations, and governments throughout the world. In this paper I want to discuss the effects of overfishing on the restaurant industry, and possible solutions to solve the problem. Fishing is an ongoing source of food for people around the world. In many countries it is a food staple in their everyday diet. In more modern societies eating fish has become a sensual experience, and not just for the wealthy. It hasn't been until population explosions in the last century that the demand for seafood has led to more effective fishing techniques and technologies. Now the demand for popular fish like the salmon, tuna, sea bass, cod and hoki, which is the key fish in McDonalds filet o' fish, is diving wild populations to dangerously low levels. The methods used to catch the amount of fish demanded by the industry do not leave sustainable populations in the wild. In an attempt to preserve the fish population, governments have set limits on the minimum size that may be harvested and how many of each may be taken. Boundaries have been set up saying which areas can be fished and which ones should be left alone. A number of smaller fisheries have gone out of business because of the limits imposed by the government. This leads to even less fish being harvested and brought to market. Therefore the amount and varieties of fish at markets are smaller and can cause shortages for wholesalers and restaurants. Some restaurants will no longer have the variety on their menus that they used to enjoy. If a restaurant thrives on its seafood menu they may be unable to cope with the shortages and will go out of business. In the ...
Overfishing is a harmful practice, that will eventually lead to the collapse of aquatic ecosystems, if it’s not dealt with promptly. Overfishing emerges from the combination of our over consumptive society mixed with the great profits that come from hauling in a good catch. The consumers demand for fish in Japan seems to be at an increasingly high rate due to the enjoyment and cultural values that arise from sushi and other traditional dishes involving seafood. Approximately 23 percent of Japan’s protein intake comes from the ocean, and as a nation consumes 7.5 million tonnes of seafood annually. CITATION
Did you know that more than 90 percent of all organisms that have ever lived on Earth are extinct? According to Pandey, the author of Humans Pushing Marine Life toward ‘Major Extinction’, nearly 10,000 species go extinct each year, and this rate is estimated to be 1,000 times higher than the natural extinction rate (1). Human beings are causing irreversible damage to the oceans and their wildlife, which is being led by two major reasons: Commercial fishing or over-fishing, which damaged the marine environment and caused a loss in the marine life diversity, and pollution, which is a primary way of the extinction causes that drastically modifies the marine life habitat. As a result of the commercial fishing and pollution, many of the marine species will start disappearing of the oceans. Briggs emphasizes that over-fishing “has induced population collapses in many species. So instead of having less than a hundred species at risk, as was the case some 30-40 years ago, there are now a thousand or more (10).”
