A lot of saltwater fish are edible. In fact, many of the fish we eat come from the ocean such as tuna, flounder, halibut, mackerel and mahi mahi. Most of the saltwater fish we find in the grocercy store and in restaurants are harvested by commercial fishing enterprises; but for many, there's nothing better than getting out on a boat, whether its a charter or their own, and landing a prize fish they can take home for dinner.

Anchovies are found in saltwater, and although they have a salty taste, it is not from the saltwater in which they reside. Processed anchovies are preserved in salt, so they often sit for long periods of time in salt baths. But if you are not a fan of salt, try a white anchovy. White anchovies are not cured in salt so they have less of a salty taste. They do, however, perish more quickly.
