And I *know* some of you will be going "Huh?" :-)
Most of our agricultural animals are domesticated breeds: they don't really have wild versions extant anymore. The domestic versions of cattle and sheep rely on man's tending to produce in the amount we want.
But we don't have any fish like that. The goal of the projects to domesticate fish is to come up with variations of fish that analogous to the common cow.
