Trash fish and Bycatch

I just finished reading with great interest an article in Edible Dallas about trash fish and bycatch.  http://www.ediblecommunities.com/dallasfortworth/fall-2011/edible-enterprises.htm

I, too, fish and eat many species that most folk don't take seriously. I love bluegill and most fish in the bream family.  As you will learn in the article, commercially speaking for us in the US,  trash fish and by catch are those un-targeted, commercially unviable species that are thrown back, dead or alive, mainly dead or injured.  Wasted.

Consider this,  our beloved Chesapeake blue crab was once a trash species beaten out of nets of bay fishermen.  Wasted.  On menus during the late 1800's and early 1900's a crab cake was often cheaper than a peanut-butter and jelly sandwich.

Mmmmmmm!?
