The Caribbean spiny lobster Panulirus argus (Latreille, 1804) supports the most valuable fishery in Cuba, and generates a net income of around US$70 million per year, it provides direct employment to 1,110 fishers and indirect employment to approximately 7,800 people (Puga et al. 2006). The total catch of spiny lobster grew until the early-mid 80s, when reached about 12,000 t. In the early 90s, landings decreased along with the Cuban economy, but by the middle of the 90s it began to recover, but…

eggs. In addition, many fish species rely on horseshoe crab eggs for food. Horseshoe crabs are currently exploited in three industries: the bait fishery, the marine live fishery, and the biomedical industry. Horseshoe crabs are used extensively as bait in the American eel and whelk fisheries along many parts of the Atlantic coast. The marine life fishery collects live horseshoe crabs…

interact with various types of fishing vessels, which gives rise to incidental capture with high rate of mortality. This interaction causes problems not only for turtles, but it also generates financial losses for the fishermen and fisheries (Domingo et al., 2006). Fisheries by-catch (both coastal and high seas) among other reasons have been identified to cause mortality and decline of sea turtle populations. Sea turtles have been existing for 110 million years and are known to have survived the…

As mentioned above, before the Industrial Age, fisheries had little to no impact on fish populations because of the fact that fishermen were using slow and old methods to catching fish. But when steel ships powered by electricity and advanced weaponry were introduced, fishing became highly mechanized and…

Shark has died and contaminates other fish. This is done so the fins can be sold on the black market, fins are sold for about $650 per kilogram (about 2.2 lbs) so they are in high demand ("Shark Truth." Shark Fin Trade –.). The number of Shark fisheries has exploded, and there are signs that some Shark populations have declined dramatically. According to one estimate, by researchers at Dalhousie University in Nova Scotia, 100 million Sharks are now killed annually, on average, (Baum, Julia K.,…

In 1992, the Canadian Newfoundland Cod fishery collapsed which resulted in up to 40,000 people being put out of work. The area was once known for its highly populated waters but was soon devastated by overfishing by both the community and fishing industries. Economists have tried to theory in particular was more significant than the rest. The rational choice theory may provide an answer as to why the disaster ensued. The rational choice theory is a key aspect of social sciences and it is viewed…

The seven categories are “fisheries bycatch, resource use including legal and illegal harvest and numerous other human activities that cause turtle mortality, construction and development, ecosystem alterations, pollution, species interaction, and other factors” (297 AB Bolten et al). Some of the major factors are fisheries bycatch and the construction and development near coastal environments. Fishery bycatch are accidental occurrences that kill various species…

al 2012). On the other hand, the marine aquarium trade is highly mobile, which allows the wholesale fisheries to move to another country’s .line when the current .line has overfished and damaged the ecosystem surrounding the coral reef; this type of business gives no incentives to hold a sustainable workforce and company, therefore, it only helps communities…

Sea lampreys have had an enormous negative impact on the Great Lakes fishery. Because sea lampreys did not originally be part of the great lakes ecosystems, their aggressive, behavior gives them a strong advantage over the fish native to the Great Lakes. Sea lampreys prey on all species of large Great Lakes fish.…

tragedy of the commons within fisheries, as all the fisherman look to take up as many fish possible, no matter size, because it will benefit him more. Society is facing this tragedy, as where Sorlien fishes used to be the “Tuna capital of the world”, but now society cannot find a tuna ‘within 20 miles’ of the harbor (Tierney, 2000). There was no management of the size of tuna that could be caught, so fisherman took them…
