While environmental concerns are often brought up as a strike against the viability of high-intensity coast aquaculture, the fact is, that it is better than the environmental degradation of the alternative. While high-intensity coastal aquaculture may have its drawbacks, it in no way compared to the destruction that has come with the overfishing problem in the last century. Additionally, if done in a smart way, high-intensity coastal aquaculture might even have positive environmental impacts. Filter feeders are some of the more sustainable options when it comes to high-intensity coastal aquaculture. Filter feeders will clean the waters in which they are grown. In some cases, like that of oyster beds, aquaculture can provide habitat for other wild organisms in the ecosystem where the organism is being farmed. This can be especially positive if the surrounding area was at some point subject to dredging which drastically decreased habitat for wild populations.
