On the colour of the fish. I thought the feed quality and temperature of the water had the most to do with weather the fish were darker or lighter in colour.
Our camp is on a lake that is tea stained with a bunch of wood in the water. I have caught bass in the shallows just about black but when we fish the rock shoal off 40 feet of water the bass come up just about tan in colour.
Cheers Don.
Actually I will go out on a limb here and say that fish color comes more from water quailtiy and water clarity. The more clear your water is usually means the fish will have brighter colors. The more cloudy your water is most fish are more light in color with no real dominate coloration. That is what I have seen anyway.
