Much like land, the Ocean holds bounty for humans, the riches coming in the form of fish. With 90 million tons of seafood being fished from the ocean every year (Walsh, Ramzy and Horn). The Ocean, once looked at as an endless source of food, has continued to become more depleted over the last five decades. The Food and Agriculture Organization reports” that 32% of global fish stocks are overexploited, depleted or recovering and in need to be urgently rebuilt”. (“The State of World Fisheries and Aquaculture”) While larger species of fish such as marlin, swordfish and tuna have been fished out by as much as 90% (“The State of World Fisheries and Aquaculture”). As the world’s populations grew to 7 billion people, so did its taste for fish. Today, global demand for seafood has reached 38 pounds of fish per year, The United States alone eats 7 million pound of seafood annually, (Walsh, Ramzy and Horn) And the United States Departments of Agriculture (USDA) recently upped the recommended consumption of seafood to more than twice what the average American eats today, now 8 oz. or more a week (www.cnpp.usda.govs). With the worlds fishing fleets wild catch plateauing in the mid 90’s (Walsh, Ramzy and Horn), the Oceans wild fisheries can simply no longer keep up with global demands for seafood, not alone, anyways.
Aquaculture can help the ocean feed the worlds growing population and in turn, help the ocean to replenish the wild catch fisheries.
Aquaculture, or fish farming, “the propagation and rearing of aquatic organisms in controlled or selected environments,” as defined by the U.S. National Oceanic and Atmospheric Administration (www.nmfs.noaa.gov/aquaculture). Aquaculture has been around for thousands of years, with evidence of fish...

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
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.
Accoring to “Overfishing of Blue fin Tuna: Incentivizing Inclusive Solutions,” it is estimated that 53% of tuna is exploited, while Blue fin Tuna have shown a significant decrease in the stock of reproductive Blue fin tuna by 80% since 1972 (Boon 1). By these statistics, it is clearly shown how much we take them for granted. Originally, Blue fin tuna were considered an inexhaustible food supply. However, as time has shown that ignorance really is bliss. If we stop and think of alternatives on how to save the Blue fin tuna population, we would be able to preserve the species for later generations to come.
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.
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.
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
Today’s ocean managers are challenged to use scientific knowledge of fish and replace regulated fisheries with well managed sustainable resources. This can be accomplished by implementing tools such as:
Overfishing is a growing world problem. In 2013, 93 million tonnes of fish were caught
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 ...
The oceans are the most important food providers on Earth, with its fish being the main source of protein for nearly 1.2 billion people, but the issue of overfishing causes fishermen to return home empty-handed more often. To overfish is to “deplete the stock of fish in a body of water by excessive fishing” (Oxford Dictionaries Web). Overfishing has begun around 1950, and all fish species may collapse within the next 50 years according to some scientists (Mosbergen Web). The depletion of fish species is caused by industrial fishing boats that install on average 1.4 billion hooks annually, with a fish serving as bait at the end of each hook. Likewise, these boats may throw nets that can catch 500 tons of fish, with openings of up to 23 000 meters squared. Fishermen have tried to remedy this problem with aquaculture. However, the latter does not create more fish as it simply trades low valued fish for higher valued ones since most farmed fish are carnivorous (Mosbergen Web). The overlooked problem of overfishing causes the depletion of fish stocks, involves inhumane killings of intelligent animals, and has staggering external costs such as by-catches and the destruction of a balanced ecosystem.
Fish protein has been a mainstay for the human diet for centuries. However, aquaculture, which is the practice of raising fish such as salmon in controlled conditions, as opposed to the commercial fishing industry, which is procurement of wild fish from their natural environment, made its debut in the United States as a commercial enterprise in the late 1970’s according to the Eco - Justice Marketplace Project.(n.d.). This mode of salmon procurement began to develop in the late eighteenth and early nineteenth century, as a response to the declining populations of native wild fish such as salmon and trout.
The number of fish that have been hunted is remarkable and the effects are irredeemable. According to Dan Barber, “we’ve been fishing the seas like we clear-cut forests” (How I Fell in Love with a Fish 1:13). The comparison of the destruction of fish to the way the world has catastrophically destroyed forests is shattering. Nature’s food web is so flimsy and easily broken that “the loss of even one species can disrupt an entire ecosystem” (Karr et al., p. 181). Even the smallest species that seems insignificant can lead to the environment being affected, every species is connected and has multiple relationships and connections. There are different species that rely on fish for energy transferred through the food chain and the population is managed through what each species consumes. Yet, just like in the meat industry, the fish industry regards the sale and distribution of fish on a higher scale than the actual environment of the
Overfishing doesn’t only occur in the U.S, but we are the only country that makes regulations for the amount of fish we can keep. Other countries do not make regulations which makes overfishing even worse and it is ruining the solutions we are trying to make. "Overfishing and pollution also threaten coral in Madagascar. But climate change -- and the warming and ocean acidification that come with it -- is expected to land the soundest blow." (CNN, Sutter) This reveals that overfishing happens all over the world and it affects many people. If the fish are being overfished, than it will affect the human food
Overfishing is the most major problem related to oceans, but it is also the most overlooked. Fishing has been going on for thousands of years, and fish have always been seen as a renewable resource, that would replenish itself forever for our benefit. But around the world there is evidence that fish are not recove...
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).”
