Over the past 40 years, the International Commission for the Conservation of Atlantic Tunas (ICCAT) reported a decline of 72% in the population of eastern Atlantic and Mediterranean stock and an 82% decline in the western Atlantic stock (NOAA(a) 2009). The bluefin population has been continuously declining for several years and despite some measures being taken to manage the population in the Atlantic, it still remains highly hunted and highly coveted due to the high demand and increasing scarcity of this fish. The species is prized by both wealthy sushi consumers due to its rich, fatty flesh and by fishermen who can sell a single catch for tens or hundreds of thousands...

...dollar fishing enterprises. In North America, for many of us fish arrives on our plate by way of a long commodity chain ending at the local grocery store, and is a product we expect to see available daily as much as we might expect to see bread, milk, and eggs. Internationally, fish have different meanings; important culturally and economically, in some places what the ocean provides is the only available means of survival. However, the sea around us is changing, in temperature and in species composition. What species remain...

...a popular sport fish among anglers due to its reputation as a formidable adversary, and the value of it on the market for table fare. The advent of blackened recipes from the bayous of the southeast has also increased its popularity. Red Drum Fisheries Management of Coastal Florida The Red Drum inhabits inshore, near shore, and offshore waters throughout the Gulf of Mexico and the Atlantic Ocean. The adults spawn in rivers, bayous, and tidal areas and the fry will reside there for up to four years. This species can reach lengths of forty five inches and weigh as much as fifty pounds. Spawning is triggered by cooling waters and a decrease in daylight hours associated with late summer and fall. In 1989, the Red Drum was considered overfished in large part due to the fishing pressure placed on the species by recipes of “Blackened Redfish” introduced in Louisiana Cajun style restaurants and the chef’s that enjoyed success from the new menu item. In an attempt to control and regulate the harvesting of the species, the Florida Fish and Wildlife Conservation Commission (FWC) instituted a slot limit of eighteen to twenty – seven inches with a bag limit of one per person. They also mandated a closed season from March to May yearly. Commercial harvesting of the fish was outlawed completely to the chagrin of commercial fishermen statewide. These measures have been viewed as a success by fisheries biologist and the FWC in general as the goal for the stock rebound of forty...

We will produce a case study which includes an evaluation of three different ways in which we can improve the status quo. The report will include * An introduction of the issue. * A summary of at least three journal articles relevant to the issue. * Evaluation of your three improvement options. * Self-reflection on how you could improve the work that I have submitted for this assignment. 2. Environmental Issue 2.1 Overfishing The environmental issue I have chosen for this assignment is Ocean Overfishing. Overfishing is when a particular type of fish is harvested so often and in such great numbers that the population of that fish is severely depleted, resulting in endangerment and potential extinction. This generally is the result of commercial, rather than recreational, fishing. Overfishing has implications well beyond marine life; it affects the human food supply...

...Every year a report is given to the ICR of Japan on the number of catches and then the ICR sets a price for wholesalers in the fish market. In recent years, due to the falling demand of whale meat, both wholesalers and retailers have been dropping the price given to them by the ICR so they can get it off their shelves. Even if the meat was sold at the price set by the ICR it would still not be enough for the industry to break even and would still be subsidised by the government. The japanese government spent twelve million last year to subsidize their whaling industry. So even with three quarters of the meat caught last summer remain unsold why does the government continue to support whaling? Some say it’s because the japanese have a sense of imperial pride and don’t wish to bend to the whims of foreign western powers. Japan claims that it is part of their culture...

... Many fish populations around the world are declining. Many factors contribute to these declines, among them overfishing. Neubert (2005) says as long as people have fished, they have overfished, and that fishery management always has been controversial. That controversy is not surprising as it can be difficult to balance competing goals—conserve the resources while harvesting as many fish as possible. Although industrial fishing is widely responsible for depletions of fish stock in the oceans, recreational fishing also plays a part. Industrial fishers and recreational anglers have been parts of the problem. They can also contribute to the solution. Murawski (2000) finds an exact definition of overfishing to be elusive. He offers this substitute: ‘‘I shall not today attempt to further define the kind of materials I understand to be within that shorthand definition; and perhaps I could never succeed in doing so . . . but I know it when I see it.’’ Former USA Supreme Court Justice Potter Stewart, writing on ‘‘obscenity’’ Measuring quantities is not enough. Managing fisheries requires qualitative as well as quantitative measurements to determine whether or not a fishery has been overfished Recreational Fishing Recreational fishing can contribute to depletion of fish stocks.

...since its origin. In early history, marine vegetation and fish were harvested on a subsistence level. As mankind progressed, and populations increased, the nature of there relationship with marine environments shifted from a subsistence based practice to that of a commercial nature. Fish were no longer harvested on a level relative to the individuals and families it provided for, but became an industry tethered to supply and demand. This change altered the dynamics between man and the oceans when commercial fishing effectively became a "commodities market" (Brett, Clausen). Certain species carried higher values than others and fishing practices became exploitive as the supply was thought to be endless within the huge bodies of water. However, at the time marine ecology was little understood and thus sustainable fishing practices were ignored as well as the not yet realized affects the commercial fishing industry had on trophic dynamics. As commercial fishing developed and spread along with population increase, intensive extraction by industrial fisheries became normal. Increased demands were placed on the oceans and overfishing resulted in severe depletion of wild fish stocks. In Richard Ellis' book Empty Oceans, he states, "Throughout the world's oceans, food fishes once believed to be immeasurable in number are now recognized as greatly depleted and in some cases almost extinct. A million vessels now fish the...

...Bertie Barfield ENG/115 Determining the Causes and Effects of Water Pollution in Lake Huron The Great Lakes, Lake Erie, Michigan, Huron, Superior, and Ontario, are our largest freshwater system. Lake Huron, like the other Great Lakes contain many species of wildlife, and is in danger of being polluted. This pollution is harmful to fish, wildlife stocks, and to the humans of this region. At the University of Mississippi, Latham, A., Wright, E., & Tsang, A. [n.d.] produced a study that focused specifically on Pollution's Effects on the Great Lakes Ecosystem. Determining the causes and effects of water pollution in Lake Huron may facilitate new ideas and solutions for cleaning up our waterways’ and improving public health. Although there are many causes of Lake Huron’s pollution, most fall under three categories: 1) Point-source pollution; 2) Nonpoint-source pollution; and 3) Air pollution. Point-source pollution refers to mercury, fecal matter, and sewage, from treatment plants or industrial facilities, being dumped into the Lake. Nonpoint-source pollution refers to runoff of polluted water from crops or lawns which contain contaminants. These contaminants may be oil, sand, salt from roadways, agricultural chemicals, and nutrients and toxic materials from urban or rural areas (The Lake Huron Centre for Coastal Conservation, 1998-2012). Additionally, air pollution is also a major concern. According to the Lake Huron Centre for Coastal Conservation, “…the...

...Nile Perch in Lake Victoria By Introduction Lake Victoria is largest lake in Africa, seventh largest in the world by volume. And second largest freshwater lake in the world. (PRINGLE, 2005) The lake is surrounded by three different country’s Tanzania, Uganda and Kenya. Figure 1 depicts Lake Victoria and the surrounding countries. All three countries share the lake and its resources, but one of the biggest issues is that the governing laws involving the resources and the lake regulations are different in each country. (Lowe-McConnell, 1994) As an economic stand point the lake produces an annual catch of roughly 400-500,000 tons of fish bringing in around US$250,000-500,000. (Blake, 2005) The lake itself has around 2 million people that either directly or indirectly depend on fishing activities to support their lives. Lake Victoria is the head waters to the Nile River. The Nile perch (Lates niloticus) can be distinguished by their silver coloring and blue tint. They have sharp black eyes which are surrounded by a luminous yellow outer ring. The juvenile Nile perch can be seen with very dark markings beaming from their eyes with extensive dark markings on their body which in time will fade with age. (Blake, 2005) The female Nile perch generally grows larger than the male. Certain bones such as the pre-opercle and pre- orbital are guarded with spines. The Nile perch is known to grow extremely fast during the first year of existence. (Blake, 2005) The growth...

...Buddhist perspective will cause the depletion and over all extinction if nothing is changed. Bluefin Tuna populations in the Atlantic Ocean have declined over 70 percent in the last thirty years yet because seafood is a global commodity being flown into markets around the world the demand has become unquenchable. Overfishing for Bluefin continues scientist expect the fish to become extinct by 2012 if nothing changes. (PBS.org) The Bluefin Tuna is a species of Tuna native to both the western and eastern Atlantic Ocean as well as the Mediterranean Sea. This is a relatively large species of fish. A full grown male can average six to eight feet long and can weigh up to 770 pounds, although the Bluefin is capable of reaching over one thousand pounds. Bluefin Tuna are robust and rhomboidal in shape. They have dark blue upper body and grey below with a gold glint covering the body. They also have bright yellow caudal fins. Bluefin can live up to 30 years but due to heavy fishing mortality few specimens grow to a mature age.("Northern Bluefin Tuna") Bluefin are carnivores in nature they typically hunt small fish and invertebrates such as sardines, herring, mackerel, squid, and crustaceous. ("Northern Bluefin Tuna") Female Bluefin are though to...

...are sharks really preying on humans? I view sharks as God’s perfect predator and scavenger. Sharks, like lions, weed out the sick and slow fish to keep the population strong. They also scavenge on the bottom of the ocean any carcasses that settle there. The attacks on humans are more likely the shark “tasting” to see if the movement is a fish. When the shark realizes that the human is not its prey, they move away. Sharks can be found all over the world’s seas, from the equator to polar regions. We are currently aware of about 480 species and there are still species to discover. Some species, known as benthic, dwell mainly on the ocean floor. An example of a benthic is the nurse shark or ray shark. They scour the ocean floor for food. Other species are known as pelagic, meaning they spend much of their time navigating the open seas. Most of the species that we are familiar with are pelagic. Some species even inhabit rivers and lakes. The Bull shark can migrate into rivers and lakes. One important feature of sharks is that they are made up of cartilage not bone. There has been research done on shark cartilage to see if it has any cure properties as sharks do not get cancer. Some people have been known to give shark cartilage to their animals to help with old age and strengthen bones. Sharks also differ from fish as fish have a swim bladder in their upper body cavity, where as sharks have an oily liver to help them keep afloat. A shark’s skin is covered by small-toothed...

...The report also examines the qualitative aspects of the relationship between biodiversity and employment, which are found to differ between the EU and developing world. In the EU, employment related to biodiversity often provides new and skilled employment opportunities for a population increasingly disconnected from the land. In developing economies, however, much of the employment linked to biodiversity is in poor quality, low paid subsistence jobs in the primary industries. Nevertheless, more sustainable farming and forestry practices offer potential both to maintain biodiversity and to enhance employment by supporting safer, more lasting jobs linked to local livelihoods rather than centralised systems of production. Nature conservation and ecotourism also offer opportunities for skilled, knowledge-based and sometimes relatively well paid employment, often helping to diversify local economies and the employment opportunities they provide. The connection between biodiversity, ecosystem services and jobs There is a lack of knowledge about the point (thresholds) at which changes in biodiversity will impact ecosystem services to such a degree that economic activity and jobs can no longer be sustained. The vulnerability of ecosystem services to changes in biodiversity varies considerably depending on the spatial scale, the type of ecosystem service, and the aspect of biodiversity being considered. For certain ecosystems, such as coral reefs, mangroves, or tropical...
