The allusive bluefin tuna is one of the largest, fastest and highly sought after fish in the wild sea. The Bluefin tuna can weigh over half a ton, grow to over four metres in length, and dive to depths of 1,000 metres. They can reach speeds of 70 miles an hour and even raise their body temperature far above that of the surrounding water in order to traverse arctic waters. They are among the most ambitiously migratory of all fish, with some tagged bluefin being tracked swimming from North American to European waters several times a year. The bluefin tuna is unique, a perfectly adapted products of evolution. They are also dangerously close to becoming extinct (Brown). Today, the bluefin tuna has been fished out by 97 percent from pre-fishing levels in the fifties (Walsh). Much of that depletion in stock comes from overfishing. Fished for their dense, dark red meat used in sushi, the Bluefin tuna has become a highly valuable fish for commercial fishing as consumers continue to want more and will pay high prices to get it (Foster). Scientist however, request sushi lovers to stop eating the bluefin tuna, to help stocks regain balance (Walsh).
While much of the developed world enjoys sushi as well, Japan itself consumes 80 percent of the bluefin tuna caught worldwide. In Japan, where sushi is a cultural delicacy, and is taken very seriously, the best pieces of sashimi or O-Toro which are small, raw, thinly sliced pieces of Bluefin, can sell for as much as $24 a piece for a 1 oz. portion in upscale sushi restaurants. (Foster) At the beginning of 2013, at the Tsukij fish market in Tokyo, the best example of the price of a bluefin tuna came when a single Bluefin tuna was sold for $1.78 million dollars. That particular bluefin weighed 489 p...

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.
Two friends go out for lunch to their usual favorite sushi restaurant. They are seated and given their menus, they knew they were going to get their usual but noticed the prices have increased. Prices have gone up, and some replaced with imitation fish meat, since the last time they ate there. What might have caused this? Due the demand of fish, the price for them also increases. It’s a simple supply and demand logic, but not only is it due to the demand for these fish, it can also be due to their rareness. Over-fishing can cause what is rare and which fish species isn’t. Commercial fishing may cause fish species to go extinct, or bring in new types of fish to take the place of the other fish. In tuna we
Hong Kong is the biggest consumer/transshipment centre for the live seafood market, including for the Humphead wrasse. Hong Kong re-exports significant but undocumented volumes of Humphead wrasse into mainland, particularly southern, China, according to traders and market surveys. The live reef fish industry in Hong Kong is worth over US$500 million, with Hong Kong consumers willing to pay up to US$175 / kg for the smaller individuals. The most preferred trade, or market, size for this fish in the export trade as food is 'plate-sized' – between about 30-60 cm (mainly 30-45 cm) total length.
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).
All pets need food, to help them grow and be healthy. There are different types of brands to choose from, some with different flavor and different color. However, when it comes down to Goldfish food, there is only one type of flavor and can be sold in the form of flakes or pellets. The cost of buying these foods ranges from $1.97 to $5.24. For Betta fish they have an option of eating three types of food, they include freeze dried bloodworms, freeze dried brine shrimp and pellets. The cost of these foods ranges from $1.69 to $3.74. When it comes down to feeding time the goldfish is recommended to eat two to three times a day, each feeding session lasting one to two minutes long. For an adult betta fish it is recommended to eat one time a day, having the session go for about two minutes. However, if the betta is a young one it is recommended to eat two times a day, each session lasting two minutes as well. Goldfish having more times per day to eat is costly because the food will run out quickly
One of the most prominent marine hunting nations in the world is the Japanese. Commercial Whaling has been a big part of Japan’s industry and economy, since the 17th century, it has been one of the main sources of food for the Japanese people. During the 1900s, whales became an important part of the Japanese diet because it provided a lot of protein and was accessible to Japan during World War II when food was scarce. The year with the highest number of whales caught by Japan was in 1962 when 226,000 tons of whale meat was sold nationwide. In 1982 a decision was made by the International Whaling Commission that would ban commercial whaling in Japan, this was known as the moratorium that was finally enforced in 1986. Unfortunately the moratorium was only successful for a couple of years; shortly after Japan was able to hunt whales for :scientific research” which did not violate...
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
Back in the dynasty the Emperors would serve the dish to honor the guest, because they believed it had healing benefits from the concurring of a shark (Fairclough, Caty). Fin soup still occurs today even when not on special (Fairclough, Caty). In addition the shark fins for can sell for a pretty penny anywhere from $500 a pound or even $1,000 a kilogram (Fairclough, Caty). As a matter of fact, fishermen in Melbour, Segal would export $1300 pounds worth of shark fins a week. It was recorded that a single adult fin sells for $80 and a two-meter monster can sell for $300. Additionally, 1 out of every 100 sharks reported killed between 2000-2008 comes from these fisherman(Hinshaw, Drew). (commentary) about Its question that fisherman practice “unsustainable finning” because it does pay nice , but the amount of money gained by finning isn’t comparable to how much sharks are worth to our economy. The global value of shark finning is around $630 million but is declining, while shark tourism is worth $312 million and promises to be worth $780 million in 20 years ( source 8). Human activity of finning isn’t the only reason to the decline of Great White sharks, human protection is another
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...
Moving onto the first point, the Japanese’s diet consists of a large portion of fish. Without the contiguous bodies of water such as the Pacific Ocean, Inland Sea, Sea of Japan, Korea Strait, East China Sean, and many others, fish would most likely not be a staple food of Japan. The specific term, Sashimi, is used to describe a stylized way in which some fish is prepared in Japan. Sashimi is basically raw fish. It is a delicacy in Japan and is traditionally considered to be one of the finest ...
