http://www.recirculatingfarms.org/fish-farms-threaten-gulf-of-mexico/ To understand the major problems associated with ocean fish farms, it’s important to picture one: thousands of fish trapped in massive cages, eating, excreting and growing. Fish feed, antibiotics and other chemicals can be regularly pumped into the pens, and the excess washed into the surrounding waters, causing a wide range of changes in the local ecosystem. Farmed fish frequently escape, thanks to inclement weather, predators causing damage to pens, or even human error or equipment failure. Escaped fish can spread disease and parasites to wild fish and out-compete them for food, habitat and mates. As a result, ocean fish farms can threaten the health of the same wild fish populations that supposedly would benefit from reduced fishing pressure thanks to increased availability of farmed fish. Harm to wild fish and their habitat, of course, means economic harm to the fishermen too. In addition to perhaps a reduce...
