I think there's a whole lot more to this than fish size and color over 1 year's time.
How about fish longevity, liver function, overall health long-term, effects of feed on water quality, etc..????
Not to be a party pooper but I feel the end goals are far more complex than what meets the eye.
You're right, Snipe. I am taking a shortcut due to lack of time & money to really do this properly, hence the "sloppy test". May prove absolutely nothing, but should be interesting anyhow.
