The Downside of Aquaculture Growth
- Overfishing. Yes, ironically, unchecked, un-evolved aquaculture feeding methods could actually increase levels of overfishing. This Quartz article nicely outlines why. As many carnivorous species, like Salmon, require animal protein as a part of their diet, much of their food is derived from feeder-fish like sardines and anchovies. These fish are caught in mass quantities, ground up, and pelletized. Therefore as aquaculture production grows, so does demand on feeder-fish. Luckily, there are companies working towards a vegetarian fish feed that would solve for this problem.
- Environmental degradation. As aquaculture grows, there is the potential for farmers to conduct less due diligence before settling on a mariculture site. One of the biggest knocks against aquaculture is that unless the fish pens are placed in high current areas, the fish waste accumulates and ends up creating oxygen-poor dead zones, killing all other aquatic life. Well placed aquaculture farms can mitigate this phenomenon by allowing strong current to distribute the waste along a larger area, but if an investor is telling a farmer to build now, he/she might take the money and turn a blind eye towards the long-term impact.
