what affects coloration of fish?
Posted: Mon May 22, 2006 1:26 am
I've noticed different colorations of fish (bass and bluegill) caught from seperate ponds
for example, fish caught from a clear pond with
abundant plant and algae growth were much darker in coloration than fish caught from a muddy pond with little plant life. in fact the fish caught from the muddy pond were nearly white in coloration with very light green on the back, the bluegill showed almost pinkish coloration around the throat area but were generally whitish (big bull bluegill). My theory is the muddy pond's water clarity is enough to hide these fish from predators, and enough to still give the bass an edge when ambushing prey. There's noo need to adapt to the local surroundings or native plant life to "blend in",. the clear pond is just the opposite. but what would happen if fish from each pond were to be introduced in opposite bodies of water, would they adapt over time or is their coloration permanent?
if it is, would it take many generations of fish to eventually start to blend in and adapt?
