Saving the Bluefin Tuna Essay

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

Instead of keeping the dolphins in the nets that they catch the other fish with, they are required to release the dolphins from the net as soon as possible(NOAA 5). This is done carefully so that “the dolphins are released alive(NOAA 6).” This allows more dolphins, despite still being bycatch, to live through the process and carry on with their lives. They also catch tuna in ways other than following dolphins, such as using logs or tuna caught on a trip in which no dolphins are harmed(NOAA 12). This type of tuna fishing allows fishing industries to put the Dolphin-Safe label on their tuna(NOAA 11). Fishing industries have already taken the necessary actions to stop cetacean bycatch as much as they can. How much they have changed their gear and their methods in order to compensate for the cetaceans supports that cetacean bycatch is no longer an

The earliest accounts of overfishing occurred in the 1800s, when the demand of whale blubber nearly wiped out the whale populations. In the mid 1900s, the harvesting of Atlantic cod, herring, and California sardines drove them to the brink of extinction. These high disruptions cause regional depletions of animal resources which is starting to cause a global problem. There has never been a more urgent time for fishing nations to make a commitment towards the sustainability of our oceans. More than 80% of the world’s fisheries have been, or are being pushed beyond their limits and are in dire need of strict management plans. Populations of fish and elasmobranch fish such as tuna, grouper and sharks have been declining to the point where the survival

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

Anyways it’s not like fast food fish sandwiches are required for us to survive. Also fish is wasted very frequently, it expires or is not eaten, so that is just harming our resources for no reason. People need to realize that fish is important, but could be used in a much smarter way. Many are reasonable and try not to be wasteful, but too many people are. Undoubtedly, if we continue this pattern of wastefulness with our ocean's resources there will be consequences. Many statistics and facts back this up. The rules and regulations we are putting on commercial fishing simply aren’t getting the job done. Our ocean’s fish population has declined so much in forty five years and the overfishing by commercial boats hasn’t gotten better, just worse. Remember the fate of the ocean’s resources is in our very own hands. Works Cited "The Threats of Overfishing: Consequences at the Commercial Level." DUJS Online. N.p., 29 May 2012. Web. 23 Mar. 2017.

Black sea bass is an important recreational and commercial species along the Atlantic coast of the U.S. The market for black sea bass is for human consumption and is primarily sold fresh or frozen. In May of this year, NOAA scientists declared the southern stock of black sea bass successfully rebuilt. The catch limit for this popular fish will more than double this fall. The rebuilding plan was required by the Magnuson-Stevens Fishery Conservation and Management Act, which requires that overfishing end immediately, that overfished stocks be rebuilt, and that stocks be subject to annual catch limits. The fish are also larger on average and are showing up in places where they haven’t

It is not educational. Teaching adults and children to dump five tonnes of critically endangered southern Bluefin tuna into cage should not be considered as educational [2, Pge 1]. Since the tuna are going to be handfed and constantly in contact with humans they will not display

This means that they can regulate their body temperature and survive in almost any temperature of water. They live mostly in cold waters such as Newfoundland and Iceland. They spawn once a year in the warm shallow waters of the Mediterranean Sea and the Gulf of Mexico. The aggressive predator eats other bony fish and invertebrates as adults, and smaller fish such as Zooplankton while they are young. Since they are high on the food chain, they are only eaten by toothed whales, ocean sharks, and the biggest billfishes. The Atlantic Bluefin Tuna travel to warmer waters to procreate once a year. According to panda.org, female tuna can produce up to 10 million eggs per year, but only a few survive. The average lifespan of the tuna is 15 years, unless they fall victim to

The Atlantic and Pacific Coasts fish stocks overall show little improvement, despite the management strategies that have been implemented to try to increase fish population. This is primarily due to overexploitation

The endangerment of the Blue whale has come as a result of not only direct harm such as hunting, but also indirect factors like environmental changes and boat collisions. However, none have drove the Blue whale to endangerment as much as commercial whaling, which is still practiced today by three remaining countries: Japan, Norway, and Iceland. Through various controversial studies on whether whaling should be illegal word wide, one must constantly question the importance of the Blue Whale for success of the planet’s future.

In order for there to be plenty of fish in the years ahead, fisheries will have to develop sustainable fisheries and some will have to close. Due to the constant increase in the human population, the oceans have been overfished with a resulting decline of fish crucial to the economy and communities of the world. The control of the world's fisheries is a controversial subject, as they cannot produce enough to satisfy the demand, especially when there aren't enough fish left to breed in healthy ecosystems. Scientists are often in the role of fisheries managers and must regulate the amount of fishing in the oceans, a position not popular with those who have to make a living fishing ever decreasing populations.

So if you spot a group of any of these, there are likely to be some tuna nearby. Found in tropical and sub-tropical waters, yellowfin are a prize catch due to their speed and strength. They're a challenging catch that's delicious too.

According to the United Nations, 17% of fish stocks worldwide are currently overexploited; 52% are fully exploited; and 7% are depleted. This means that only an estimated 20% of worldwide fish stocks are not already at or above their capacity(Seafarms, 2013). Catches of Pacific herring have decreased by 71% since the 1960s, with Atlantic herring catches falling by 63%. Atlantic Cod catches have fallen by 69% in the same time(Seafarms, 2013). These are just a few of many facts and statistics on the topic of overfishing. The effects of these statistics and facts impact people’s and animal's lives around the

The triple bottom line of fishing is influenced by sustainability in many ways. One way is the demand for fish increases with population. As well there are new laws limiting fishing, ultimately forcing once
