“Overfishing occurs when more fish are caught than the population can replace through natural reproduction”. CITATION
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
Therefore their society relies heavily on the ocean as a main food source. In any industry the supply will meet the demand as long as there's a profit to be made, and this is reflected in the overfishing in Japan. Unfortunately, overfishing

Many of the methods used in commercial fishing are very destructive to the aquatic systems. Industrial ocean trawlers scrape the bottom of the water, often dragging up the seafloor with them. This destroys the habitat and kills many of the bottom dwelling organisms that are vulnerable to these practices. There is also a large amount of marine animals that are unintentionally caught by the large nets. These animals are considered bycatch, having no value to fishermen and are usually killed. These large fishing vessels also add a significant amount of pollution to the water. Fishing vessels cause oil spills as well as discharging chemical elements and wastes into the water. The thousands of of trawlers that pass through Japanese waters create large quantities of water pollution that can devastate aquatic life by changing the chemical composition of the water and affecting all the organisms that inhabit these
The first genetically modified animal has been given the green light to reach dinner plates.
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...
Overfishing is defined as a form of overexploitation where fish stocks are brought down to unacceptable levels. In the UN Food and Agriculture Organization’s 2 yearly report (SOFIA), it states how over half of the fish stocks, worldwide, are fully exploited. Other research has shown it only takes 10-15 years of industrial fishing to obliterate a tenth of the intended species. Overfishing causes a ripple effect that hurts the entire ecosystem. The balance of the chain depends largely on the interaction between the predator and the prey.
Simply, overfishing depletes fish stocks. The consumer demand for fish has risen dramatically over the past decade or so, so much that fisheries are designing new and innovate ways to catch more fish, and at a faster rate to meet consumer demands. What fisheries do not realize, though, is that their removal of fish from the oceans is too great and far too fast for new fish stocks to be made. So, no mating is occurring, leaving the oceans emptier each day. If this rate continues, all fish in the ocean will be almost non-existent. Already, we are experiencing a major decline in fish population: "In 2003, a scientific report estimated that industrial fishing had reduced the number of large ocean fish to just 10 percent of their pre-industrial population. "(par.6).Overfishing brings the main consequence of decrease in the fish population. People rely on fish for survival (in some countries, fish is their only source of food), and they rely on marine life for products (goods like lipstick, petroleum jelly, make-up, etc.)
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
You're planning a vacation to Hawaii and want to do some fishing while here. If you're planning to hop on a charter sport fishing boat or some other commercial offshore excursion, you don't have anything to worry about except for showing up at the dock on time.
Black Fish is a documentary released by Gabriela Cowperthwaite on July 19, 2013. The main purpose of this documentary was to expose the cruelty animals experience by being locked up in Sea World. Mainly, this film focuses on Orcas; this is because most people attend sea world to watch these wild animal perform shows. Specifically, the footage lights up Tilikum, a wild orca who was related to the death of three trainers, which by the way were blamed for their own murder. Tilikum was cruelty trained in order to obey and perform the huge shows Sea World makes by using these animals. In the film the use of footage and videos recorder by people who have attended these shows are used, which makes the film reliable and explicit.
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
Jack: Yes, Overfishing is a global disaster. Over three quarters of the world is covered by oceans and are full of fish. You see, lots of people love to fish, but some people take it a bit over the top. Fishermen fish almost everyday but some of them fish for hours and hours catching a ton of fish. Millions of people rely on the ocean every day and other people in other parts of the world that need the fish in the water to eat and survive on.
Demand, revenue, cost, and profit are the driving forces behind any economy. This notion is taught to most students in grade school and will carry on through the rest of their lives helping them make the most educated decisions they can. Logically, the greater the demand for something, the greater the profit will be. Whaling used to be a sizable part of the economy, due to the innumerable uses of a whale’s by-products, and consequently, there was a substantial profit margin. Presently, the largest demand for whaling is by Japan, Norway, and Iceland all of whom partake in whaling for either commercial or “research” purposes. However, the demand and revenue from whaling do not outweigh the costs that have tolled on the species. This practice is largely scrutinized by conservationists who believe that commercial whaling is going to bring some species of whales to extinction. The current demand for whaling is incredibly low; however, it is still necessary to continue the ban on commercial whaling.
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 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...
Illegal, unregulated and unreported fishing, or pirate fishing, is a huge threat to the marine environment, it's bio diversity in food development is dependent on it. Losses due to pirate fishing are estimated to be between 10-23.5 billion U.S. dollars per year. Representing 11-26 million tons of fish. West African waters are estimated to have the highest levels of pirate fishing in the world. Fish is a crucial source of protein for millions of people. Fishing is the major coastal employment along the coast's. During a dramatic two year investigation, the Environmental Justice Foundation (EJF) has documented mass amounts of pirate fishing on the West Coast of Africa. Pirate fishermen are literally out of control. They are fishing in protected areas, destroying local fishermens nets and sabotaging them, hiding their names, and shipping their catch illegally at sea. They evade arrest, attack local fishermen, and abusing their own crews. The catches of these pirates have been entering the EU. the worlds largest import market for seafood. This is despite a new EU regulation. The regulation requires all fish imported into Europe to be accompanied by a catch certificate that asks for name, address, validating authority, fishing vessel name, license, and homeport. This is all declares that the catches have been declared legal.y 90% of the vessels documented by EJF fishing illegally are bottom trawlers. Bottom trawlers are are vessels that drag heavy nets across the sea bed catching all marine life in their path. Up to 75% of call the catches made on these vessels are dumped back into the sea, dead or dying. Fish is the principal source of protein for 2.9 billion people. But the United Nations recognizes 80% of the world's fisheries are e...
Unless the current situation improves, stocks of all organisms that are currently fished for food are predicted to collapse drastically by 2048 (WWF 2.) 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
The most direct effect from trawl fishing is scraping of the seafloor which causes destruction of plants and other non-living things that live on the seafloor(Agardy). This also limits the potential food for other plant dwelling under water creatures. Cornella Dean came a...
