needs of nutrition. In the report, Illustrating the critical role of human dimensions research for understanding and managing recreational fisheries within a social-ecological system framework, by Hunt et al., we look more closely at the management of recreational fisheries in relation to the fishers themselves, and how it may influence the outcomes of the fisheries ecological systems. In turn we see critical connections between the ecological and social systems, which give us great feedback on a recreational

Fish, one of the worlds’ leading food source in all regions of the world, but what if one day that food source was to deplete so drastically that one could no longer use it as a food source? What would happen to the people that rely solely on this source? What would happen to the people that relied on catching fish as a job? What would happen to the worlds’ economy? These are only a few questions that should be a concern in the result of Overfishing. The ocean is a big and mass world living among

refers to the long-term viability of community, set of social institutions, or societal practice" it creates a balance. The balance is profiting from the fishing within environmental concerns, meeting the demands and keeping the integrity of the fish population. As seen in the basic economic theory the triple bottom line describes a development that "successfully integrates economic, social, and environmental considerations in decision making" (Sustainability, p. 944). The global fishing communities have

One of these commonly arising problems is that single-species fisheries skew the age structure of the harvested populations by selecting for the largest and, thus, oldest individuals to maximize biomass harvested. This can result in several damaging effects on the population depending on the species its life history. The underlying cause is that fisheries often make the assumption that all eggs are equal, despite a large and growing amount of evidence to the contrary (Beverton and Holt 1957). Several

support the fisherman. As early as 1914, the Government was receiving reports from the U.S. Commissioner of Fisheries on the potential impact to unregulated fishing. By 1931, serious questions were being asked about

Research Paper The Environmental Impact of Fisheries and Fish Farming on a Global Scale On our Oceanography class trip to La Jolla, California, we spent a day on the Ocean Institute boat running tests and observing sea life. To collect a sample of the different fish in the area we dragged a large net in the water, which the volunteers said they don’t do often because it is destructive to the environment. I found it interesting that catching fish in this way could be harmful not only to the fish

million tons of fish a year, which apparently is the human weight of China. If our current methods of fishing keep moving in the direction they are heading. We will deplete nearly 90% of the world's commercial fish by the year 2050. With smaller tuna fisheries more and more fishermen are using hook a line methods of catching tuna. Meaning that a fisherman would throw a single line in the water and pull out a tuna. If the fish wasn’t a tuna or if the tuna was to small they would be

global economy sustainability is very important; from the biological aspect to the industries they all play a role on the marine environment. As world population increases the demand of fish rises causing overfishing. Certain laws have been placed to limit the amount of wild fishing to reduce the risk of endangerment. To meet the demand of the population, fish farms are introduced. Pollution and health related issues are part of the challenges of fish farming. Sustainability also affects social areas

ever wondered where all the fish went? Or why the fish population is decreasing? I believe that overfishing laws need to be enforced in all bodies of water around the world because it is overall bad for the environment, for us as humans, and our needs. First of all, fish is a common food source in the world especially in areas around the ocean. People all around the world rely on fish for their main food source everyday. The fish population is severely depleting because of lots of overfishing. To
