Has anybody been able to demonstrate that genetic variability has a measurable
impact on either long or short term survival? How do you measure genetic
diversity within a population?

Do the data suggest that older, more experienced fishes have trouble
"unlearning" the bad habits they pick up when raised in captivity? If so, then
I like Moon's idea. Release 'em when they're real tiny, before they have a
chance to learn anything.

Where am I going? And why am I in this handbasket?
