Is the use of fish farms, or aquaculture, an environmentally beneficial way of feeding the world?  Well many environmentalists say no, and claim that the waste from these farms hurt the environment and the overuse of antibiotics in their maintenance harms human health.  But according to the National Center for Policy Analysis, such claims are, well, fishy as modern aquaculture requires technically specialized conditions about the life cycle of each species, and then uses the creation of feed formulations that are more digestible and leach less waste.  Further, new vaccines reduce the reliance on antibiotics and other chemicals, which lessens impacts on human health. It appears this fish farming debate is a slippery one indeed!
