Fish Farming

Fish-farm cages are filthy. Contaminants from ocean-based aquafarms (fish excrement, uneaten chemical-laden food, and swarms of parasites) spread to the surrounding ocean, and the rampant disease inside the cages, in addition to killing up to 40 percent of the captive fish, is passed on to ocean fish in the area, in some cases increasing the incidence of sea lice, a deadly salmon parasite that eats away at the animals' flesh, 1,000-fold.
