1. The increase in catch by fisherman due to better technology and more fisherman has led to overfishing, which greatly reduces the populations the worlds fish. We know 31.7 percent of the worlds fish stocks and of the fish populations that are known 30.6 percent are experiencing overfishing or are already overfished.
2. Ocean fisheries increased their global wild fish catch by 500 percent between the years 1950 and 1997. In 2000, fisheries met their highest amount of fish caught, peaking at 96 million tons. Fisheries did not fall during the years 2000 to 2006 because of outdated technology and the choice to fish less, but rather because the fish population has been exhausted due to overfishing. Fisheries have become so productive at fishing with new technologies that the population of fish cannot reproduce fast enough to meet our needs. Industrialized fishing moves at a rapid rate and can typically exhaust a population of large fish by 80 percent within 15 years. The past years that have contributed to overfishing has left approximately 10 percent of large fish and ground fish in the ocean. The National Marine Fisheries Service believes that if we stop giving subsidies to fisher, their boats and their gear, we could generate $8 billion in revenue. With better management of United States fish stocks 300,000 jobs could be created.
3. The overfishing in oceans is often done in ways of selective fishing. The issue of supply vs. demand in ocean populations is quickly dwindling and when there is little supply people are willing to pay more for specialized fish. Except in this case "specialized" often means endangered. The more rare a fish is, the higher the selling price. Instead of conserving an endangered species, fisheries dri...

...fornia, Oregon and Washington put together over the past 20 years. Tilapia is another environmentally sound source of fish. The Tilapia that I consume is Farmed in tank systems in Canada. Tilapia is produced in over 100 nations and is the most farmed fish. Farmed inland, Tilapia has very little negative impact on the environment. Tilapia relies on fishmeal and fish oil for nutrition, but most U.S. tilapia farms use crop-derived ingredients to minimize the effects on other fish.
12. The "Super Green List" is a catalog that Monterey Bay Aquarium produced to help people know what seafood is caught and farmed conscientiously. The list contains choices that have low levels of mercury and have healthy omega-3 fatty acids. If I were to choose from the "Best of the Best" list, I would choose the wild-caught Alaskan Salmon because I know that it is environmentally friendly.
Overfishing is a major problem in economy today. The practices of fishing too much or too often result in a decrease of the fish population. Constant removal of fish from the oceans (fishing) accounts for both adult and baby fish. With the consistent decrease in adult fish, mating becomes more difficult or even impossible, resulting in an overall lack of fish in the oceans. Pepijn Koster defines overfishing as, "Overfishing can be defined in a number of ways. However, everything comes down to one simple point: Catching too much fish for the system to support leads to an overall degradation to the system. Overfishing is a non-sustainable use of the oceans." (par.1). When fish stocks cannot be replenished faster than they are being depleted, a reduction in fish population occurs, which is what is referred to as overfishing.
Countries, fisheries, and consumers all need to share the responsibility for conserving endangered marine life. First, governments should base their policies on scientific factors and should look for better economic incentives to stop fisheries from overfishing. Second, fisheries should use methods that are not so destructive to the fish population. Finally, consumers should avoid buying endangered seafood, even if they have to pay a little more. If these parties recognize that it is worthwhile to conserve marine species, then they must accept this responsibility.
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.
The United States Pacific Northwest has historically been a significant player in the global fishing industry. However, over the last half-century, the fish population in the area has been declining at an alarming rate. Popular species of fish such as cod and salmon have been particularly susceptible to these decreases. What once was a region flourishing with abundant fish populations, is now in danger of being exploited to the point of extinction of certain species. The majority of these population drops is attributed to increased industrialization and overfishing in the region. The ocean is a commons, as defined by Garrett Hardin in his “The Tragedy of the Commons”, and is being exploited as an open resource, resulting in a reduction of fish and industrial fisheries in the Pacific Northwest. Enforced government regulation is the only viable course of action to deter the declining fish populations. Fisheries have been exploiting the region, and limiting the amount of fish one can catch, particularly of specific species, may lead to more balanced levels of fish population.
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).
Atlantic salmon have become the species of choice to raise on farms because they are more adaptable to the farming techniques and make better use of feed so they produce more salmon with less feed. Not everybody agrees however, that farmed salmon raised in net pens are healthy for the environment or for you to eat. Over the years, there have been numerous stories in the media that have pointed out the negatives of farm raised salmon. These arguments have ranged from wastes from salmon farms, the spreading of disease from farmed to wild fish, the negative impacts of farm raised fish escapes and interacting with native fish, and recently, the effects of farmed salmon consumption on human health. The latest issue that the media got there hands on and consequently got the public concerned, was a report that polychlorinated... ...
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
Since nearly the beginning of human history fishing has been an integral part of the culture and survival of coastal communities. These coastal communities and cities have always been some of the most prosperous and successful because of the added resource of the ocean. In the beginning many areas were so densely populated with fish and shellfish that often a day’s worth of food could be caught by simply wading into the shallows. For example, some of the first English settlers to see the Chesapeake Bay described “The abundance of oysters is incredible. There are whole banks of them so that the ships must avoid them. . . . They surpass those in England by far in size, indeed, they are four times as large. I often cut them in two, before I could put them into my mouth” (Miller). This abundance had every appearance of being as infinite as the ocean that produced it but the reality was far different. Many fish stocks, including the oyster, stayed near these high levels even into the beginning of the industrial era. However the new rapid pace of technological advancement proved too much for many stocks to handle. Close shore stocks took most damage as they were the easiest to exploit. Those same oyster colonies that were once an obstacle for boats were nearly eradicated by “the 1890s harvests began to decline. Many oyster beds were destroyed and reefs had been mined away. By the 1920s, the boom was over…” (Miller). While catastrophes like this inspired many sustainable practices there are still fisheries worldwide that are headed for a similar end. Through ignorance and misinformation from the fishing industry most of the general public does not know that this is occurring. The following will serve to inform about the t...
Overfishing is a growing world problem. In 2013, 93 million tonnes of fish were caught
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 a year, being one of the world’s most valuable. However, the coasts have not been treated with respect; overfishing, over consumption, and wasteful practices have deteriorated, not only the industry, but the ecosystems and fish populations. This is a huge global issue; the worldwide collapse of fisheries is projected for 2048.
We are also catching to many fish and the fish are not able to sustain their population. There are plenty of fish on the endangered list due to over fishing and some of these fish are surprisingly commonly consumed across the United States. I’ll fill you in on the top ten: Alaskan Halibut, it’s a largest flat fish and it’s found in the North Atlantic. #2 is the Beluga Sturgeon, it’s usually consumed for its fillets and eggs that are known as “true caviar”. #3 is Acadian Redfish. #4 is Orange Rough, #5 is the Winter Skate (usually made into fishmeal or lobster bait). #6 the Bocaccio Rockfish, the most endangered in the West. #7 is the European Eel, when these juveniles are caught out at sea they have not yet spawned. #9 is the Goliath Grouper, their harvesting has been banned. #10 is the Maltese Ray, that is now only found in one area of the world, The Strait of Sicily. Most of these fish are being caught as bycatch, meaning they weren’t the intended target species. Our methods of fishing are a big contributor to this problem and bottom trawling, which is mainly used, is one of the most destructive ways to fish. Bottom trawling uses heavy nets that are dragged across the ocean floor catching everything, letting nothing escape. Simultaneously, this kind of trawling destroys reefs and habitats along the way and It could take decades to repair the damage done by bottom
Why? Our oceans cover nearly three fourths of the surface of our earth. According to overfishing.org, eighty percent of all life on earth is in the ocean, and us humans are threatening and driving them to extinction by overfishing. What is overfishing? Overfishing is defined as “To fish (a body of water) to such a degree as to upset the ecological balance or cause depletion of living creatures.” (Merriam Webster Dictionary) Recent studies from the Environmental Defense Fund reveal a bleak truth: Overfishing is depleting our oceans of sea life around the world. 87% of the world’s assessed fish stocks are at their breaking point, classified as overexploited or fully exploited. 1 out of 2 fish stocks in the U.S. are either overfished or at risk of being overfished. Moreover, 100 million sharks are killed each year. Carl Safina, world-renowned author of books such as Song for the Blue Ocean, once said, “If you're overfishing at the top of the food chain, and acidifying the ocean at the bottom, you're creating a squeeze that could conceivably collapse the whole system.” Overfishing is classified as the most dangerous threat our oceans are facing today. Worldwide, about 90% of fish stocks are gone forever. In 1990 our oceans contained at least six times more fish than they do today. Collapsing fish stocks create large ecological dead zones in our
When economic incentives overshadow moral reasoning, people often disregard, or temporarily repress moral arguments, and eagerly turn toward the economic incentives. In January 2009, a 440 lb Bluefin tuna sold for $173,000 (Keim, 2009). The average weight and size of a bluefin tuna is 770 lbs and 2-2.5 m. This high selling price reflects an irresistible incentive to catch these immense fish and sell them to the highly demanding market. Demand for bluefin tuna has grown so high that demand is starting to supersede the supply. In anticipation of resolving this problem, commercial fisheries began large-scale fishing of the tuna. Bluefin Tuna have very fast swimming speeds, which allow them to migrate between cold temperate feeding grounds and warm water spawning grounds regularly (Fromentin and Powers, 2005). Atlantic Bluefin Tuna can sustain cold (down to 3°C) as well as warm (up to 30°C) temperatures while maintaining stable internal body temperature (Block et al. 2001). One problem with the unrestricted fishing of Bluefin tuna is their susceptibility to being overfished. Northern Atlantic Bluefin Tuna in particular have life spans of over 30 years. This causes them to be more vulnerable to getting caught at some point in their lifetimes. In addition it takes them eight years to mature which leads to a very slow reproductive cycle (Fromentin and Powers, 2005). By the time they reach eight, there is a very good chance that they will already be caught eliminating their chance for reproduction. Egg production, for the individual species that do make it to maturity, appears to be size-dependent: a smaller, younger female produces an average of five million eggs, while a larger, older female can carry up to 45 million eggs (Rodriguez-Ro...
Yet over the past few decades, fish populations have been decreasing year after year. YES, WE ARE OVERFISHING OUR SEAS. Overfishing is when more fish are caught than the population can replace through natural reproduction. For most of human history, overfishing occurred through small tiny boats of fishing fleets. But in the 1900s new technology changed fishing techniques. Bigger and advanced nets and radar allowed fishing to be more quick, efficient and of more quantity. All of a sudden, fishing became a huge commercial resource. So for a while, things were going great, enough food source and lots of money.
Fishes (seafood) are known to produce protein for human consumption more efficiently than any other species, also stated by nutritionists, fish provides healthier forms of protein.
