I'm sure you've all heard this idea before, that fish of various kinds will
grow to fit their environment, and then stop growing.

Does anyone have good -reliable- information on the matter? I'm sure
everyone has opinions, and links to opinions, but I'd like to get a handle
on some facts if it were at all possible.
TIA
