The Pros And Cons Of Bluefin Tuna Consumption

One of the distinct features of any common resource is that it is a “non-excludable good1”, meaning no one can be prevented from using what is available. As discussed, the consequence of this scenario is that it will produce a socially inefficient outcome. There are differing theories on how to achieve an economically feasible marginal cost and marginal social benefit equilibrium. The difficulty, of course, is to determine what the socially optimal supply level for Bluefin Tuna should be in relation to fish stock restoration and future sustainability as well as empowering the global community to act in unison. The discussion here

Driven by such high prices, many fishermen, chefs and business owners depend on the bluefin tuna industry for a way to support their lives. Respectively so, without sustainable fishing practices and stricter regulations for the bluefin tuna, neither Japan, nor the rest of the world will even have the choice on whether or not eating and fishing bluefin tuna should be an option (Crockett).

Economic and Environmental importance: Recently, Skipjack Tuna has become the most fished Tuna in the world; they account for 40% by weight of all of the Tuna caught in the ocean. Skipjack Tuna are usually caught with purse seines or by hook and line, but their tendency to group together when Fish Aggregate Devices (FAD) are

Oceanic Victor claim that the tuna cage will not attract any more sharks than usual, which is odd to say as in other circumstances in tuna pens shark wranglers have been hired to cut free sharks that have been stuck in the nets.[4] “Tuna cages attract sharks, which are drawn to fish which sometimes die in the pens and settle in the bottoms of the floating nets. Inquisitive sharks may bite holes in nets and enter the cages or become entangled in the nets and subsequently become distressed or drown. In response, employees of tuna ranching operations will either enter the water and attempt to wrestle the sharks out of the pens, or kill the shark. Species known to interact with southern bluefin tuna operations include hammerhead sharks, bronze whalers and great white sharks. The latter species is protected under federal Australian legislation while the former two are not. Some of these interactions are shown in the documentary film, Tuna Wranglers (2007).” [3]

100,000. This number might seem large, but with 96.4% of the population declining after fisherman started hunting for these animals, the coveted fish might not be around for much longer. The Thunnus SPP, or better known as the Atlantic Bluefin Tuna, is one of the largest bony fish in the world. At one and a half Mr. Zunic’s in height and 200 bags of potatoes in weight (6-10 feet, 1500 pounds according to animalplanet.com), the Atlantic Bluefin Tuna is almost invincible, to predators in the fish class of vertebrates that is. The Atlantic Bluefin Tuna is critically endangered due to overfishing. One fish was once sold for $1.76 million due to the fish’s delicy. The Atlantic Bluefin Tuna is highly popular at high-end restaurants around the world. Boy, a tuna roll sure does sound great right about now.

You've probably heard a lot about mercury in the news, and while it can be scary, don't let it keep you away from eating fish. According to the FDA, you can safely enjoy up to 6 ounces of tuna a week. So fire up the grill and start cooking these Ahi Tuna Burgers. Top with low-fat wasabi mayo and pickled ginger, and your taste buds will go nuts for this new summer favorite.

Improper fishing has been a really big problem in the Atlantic Ocean because it damages the environment. Other problems such as pollution cause fish in the Atlantic Ocean to be contaminated and some of the species of fish and other sea life have even been terribly led to going extinct. Before we freak out and think there is no hope for our salmon salads, remember there are people who fish the proper way, some of them being in the beautiful state of Alaska. Fishing in Alaska is a whole different story when it comes to comparing it to the absurd fishing techniques that take place in the Atlantic Ocean. In Alaska, the fishing industry is by no means perfect, but it is environmentally friendly, it is an economically booming business, and it also has some of least contaminated fish in the world. That sounds good, but wait till you hear this! The salmon population continues to grow no matter the fact that fishing takes place every year at a high rate. You heard right! More delicious salmon salads on your table for the years to

Too many fish are being caught It is estimated that each year 970 to 2700 billion fish are killed and eaten. There is only an estimated amount of fish caught each year.People are taking way too many fish home in a matter of one trip. Trout and other fish are treated wrongly they do not have scales so they can not be lifted out of water as long as other fish with scales can and you have to wash your hands thoroughly with the body of water you are around. Polluting the water with junk. Bad pollutants are put in the water and it can harm fish horribly. Fish tend to eat plastic thinking it's food to eat. Some plastics carry bad chemicals that could also kill fish.It

According to marine ecologists, unconstrained fishing is the largest threat to all ocean ecosystems (Your Cool Facts and Tips on Overfishing 6). Overfishing destroys the oceanic life environments and alters the food chain. If the food chain ends up breaking, the consequences will occur throughout the entire ocean (Your Cool Facts and Tips on Overfishing, 6). For instance, sometimes fishermen out in the ocean lose their nets. While this may seem like a good thing, it is the opposite. The nets will continue to catch and kill fish for many decades. The sport of fishing does not affect solely the species that is being murdered, but it also affects other populations such as the prey and predators of the population being overfished. In the spring of 2015, sea lion pups in Los Angeles County were famished because their primary food source, sardines, were and are currently being captured faster than being replenished, according to Geoff Shester, a marine-life conserver in “Starving Sea Lions Spotlight Overfishing” in The Sacramento Bee magazine. Immoderate fishing only adds on to the number of blameless and pure sea creature

One of the important thing I have learned is how tuna stay warm with cold hearts. how animals react to rapid temperature changes, knowledge that’s becoming more essential as the earth warms. Pacific bluefin tuna are top predators renowned for their epic migrations across the Pacific Ocean. They are also unique amongst bony fish as they are warm bodied (endothermic) and are capable of elevating their

Whale meat is back on the menu at about a sixth of Japan’s public elementary and junior high schools. Whale meat, because of ocean toxicity and whales massive size, has high levels toxins. David Kirby, a professional journalist, also says “Whale and dolphin meat is also often loaded with mercury. In 2011, the EIA purchased whale meat in Japan and found that one sample contains 21 parts per million of toxic metal, 50 times above Japanese safety limits.” So if whale meat is so bad for you, why does Japan still have whale meat on their menus? Japan says that it is an effort to pass “traditional food culture” down to children. Japan's tradition of whaling has been going on since the 9th century, so it is a long tradition in their country that they want to keep alive. Not only is eating whale unhealthy, it is also affecting the whale

At the moment, the number of Bluefin Tunas is of concern as it is below 15% of what it was before the exploitation. There are three main reason as to why the Bluefin Tuna has become endangered. These include: The Lack of Marine services, Over fishing, Illegal private fishing and their Predatory Status.

Bluefin tuna eat other fish such as mollusks, crustaceans, and macro algae. Sharks and giant marine animals prey on the bluefin tuna itself. Up to 72 parasites also host on the bluefin tuna. Farming the bluefin tuna with chemicals can also impact the environment. Removing bluefin before spawning affects the ratio of offspring. The bluefin tuna reproduces by spawning their eggs. The pacific bluefin tuna lay eggs in the Western Pacific ocean. The Atlantic bluefin reproduce in the Gulf of Mexico and the Mediterranean in the west. After the bluefin tuna lay their eggs, they do not look out for them. It takes four to eight years for bluefin tuna to become sexually matured. The bluefin tuna can live up to an estimated thirty to forty years, but many bluefin tuna are captured before they have the chance to mature. The bluefin tuna can produce large amounts of eggs per year. The chance of survival for each egg, however, is 1 in 40 million. The northern and southern Bluefin tuna are critically endangered. The bluefin tuna has been exploited since recorded history began. The population is decreasing from the demand for Bluefin tunas in high end sushi markets. It is a prized fish to eat. Many chefs, mainly in Japan, buy them for a large amount of money. Also, illegal capturing of the bluefin tuna is a huge issue and illegal fishing has not been controlled and constrained well. The market for canned tuna after 1960 removed a lot of bluefin tuna from the population. Although there is not an exact number of bluefin tuna left, there is a very small amount left in the world. According to research, overfishing caused the Pacific bluefin tuna numbers to drop 96 percent. Fishing fleets from the United States, Mexico, South Korea and Japan are the main countries exploiting the bluefin tuna

Thunnus Thynnus, or the Atlantic Bluefin Tuna, is one of the largest species of tuna, weighing in at over 600 kilograms and four meters in length. It is known for its speed and takes the shape of a torpedo. In its environment, the Atlantic Bluefin Tuna acts as one of the top predators. It preys on smaller fish, such as herring, mackerel and eels. The Atlantic Bluefin Tuna is separated into two main populations, Eastern and Western. Although located in different geographical areas they are not isolated and individuals migrate between the two populations allowing gene flow. The Atlantic Bluefin Tuna’s population ranges all through the pelagic zone of the Atlantic. The Western Atlantic population spawns in the Gulf of Mexico, and the Eastern Atlantic population spawns in the Mediterranean Sea. In the fishing industry it is highly coveted for sports fishing, especially in the United States and Canada, and in the sashimi market for high-end sushi. As a result of the high demands for the Tuna it is being heavily overfished causing the population to decline dramatically. The low supply and high demand for the Tuna has made them extremely valuable; a single fish in Tokyo 's Tsukiji fish market sold for 1.76 million dollar (Bluefin, 2013). This high value of the Atlantic Bluefin Tuna has resulted in illegal pirate fishing causing more harm to the population. If the illegal pirate fishing and overfishing of the Atlantic Bluefin Tuna continues, the species will become extinct resulting

While some characteristics are similar among the different species of tuna, in general each species is distinct. The Bluefin tuna, Thunnus thynnus, is the biggest of the species. They can reach astonishing sizes and average “…up to 1500 pounds and…6-10 feet long.” (World Wildlife Fund 1) The Bluefin tuna are built like torpedoes. With traits like retractable fins and eyes that are set flush to their body, they were made for speed. They have the longest life span, living up to forty years. The next largest is the Big Eye tuna, Thunnus obesus. They are long and streamlined. They have a distinct coloration to protect thenselves from predators. In order to avoid predators from above, they have dark metallic blue on their backs and upper sides. Likewise, to avoid predators from below, they are nearly white on their lower sides and belly. Their two sided coloration allows for then to blend in the with their background waters. While smaller than the Bluefin, they can still reach an enormous size. They can weigh up to 460 pounds and they have an average length of
