Overfishing is a major problem for many aquatic species. When you choose fish, select varieties that are abundant, and forgo those that are being depleted.

These recommendations come from montereybayaquarium.org, which offers a printable pocket guide and a mobile app; below is the fall/winter 2013 guide for the Southeast. Note that these species are based on sustainable practices, not health choices. Some tuna, for example, may contain mercury.
