Are freshwater fish considered seafood? [closed]

Can freshwater fish, crayfish, etc. still be referred to as seafood or is there a special term?

In common usage seafood is any "edible aquatic life" - http://en.wikipedia.org/wiki/Seafood Also a lot of seafood is grown in "farms" so we may have to invent a new term for sea/river/tank foods!

Yes. This article on Britannica online explains.

ARTICLE from the Encyclopædia Britannica

seafood
edible aquatic animals, excluding mammals, but including both freshwater and ocean creatures.

Seafood comprises all bony fishes and the more primitive sharks, skates, rays, sawfish, sturgeons, and lampreys; crustaceans such as lobsters, crabs, shrimps, prawns, and crayfish ; mollusks, including clams, oysters, cockles, mussels, periwinkles, whelks, snails, abalones, scallops, and limpets; the cephalopod mollusks—squids, octopuses, and cuttlefish; edible jellyfish; sea turtles; frogs; and two echinoderms—sea urchins and sea cucumbers.
