The growing demand for seafood cannot be met by wild caught fish. Aquaculture is the solution to the problem of increased seafood demand. We do want to ask all the right questions in determining if the fish (or clam, or shrimp) is sustainable. Sustainable? What exactly is that? Lets define sustainable as being able to maintain (or better yet increase) the wild population of a given species. Doing no harm to other organisms while procuring the target species. Producing no negative environmental impact. So what exactly are good choices here? This is going to require you ask your local fishmonger when you buy, but here are some good choices.
- Oysters; Most farmed oysters are not only sustainable, but actually beneficial to the local water quality due to the large amount of filtration power they supply.
- Catfish; Being omnivorous catfish do not require much wild caught fish meal in their feed, and effluents are limited or treated to avoid harm to the environment.
- Algae; Lets hope it doesn't come to this, although as a food source for fish it is a great idea.
