Summary:Cage Aquacultures Environmental Effects :: essays research papers fc

Cage aquaculture in the oceanic ouputs large amounts of intemperance into the surround environment. The outflowing from the cages has elevated levels of nutrients, waste feed, feces and by-products such as medications for the fish. The effluent has a negative uphold on the local environment. The gunpoint of impact depends on the water system movement around the cages, the assimilation electrical capacity of the environment around the cages and the rate at which the effluent is produced. The effectuate of effluent on the environment is considered inconsequential to the inputs from industry and agriculture however. That being said, the ocean floor around the cages tend to be hypereutrophic and completely anoxic up to the surface. They release sulfides and separate toxins into the water as a result of lessening in the anoxic conditions of the excess organics in the sediment. The long term effects of these conditions are not known. There are no standards by which to equalize i nternationally the effects of the cages and it is hard to determine the effects, if any, on areas away from the adjacent area surrounding the cages. There needs to be work make on how to reduce feed waste, and how to quantify the effects of the cages on the surrounding environment. To complete this project, more information is needed on operations other than cage salmon in Norway.
