When I lived in South Louisiana, I learned to do as the natives do, and to call largemouth bass "green trout." Indeed, they were almost always remarkably green.

The bass in my North-central Alabama pond are only sometimes and somewhat green, more often various shades of sliver to dark. Perhaps the difference is that the water in S. Lousiana is generally green and that there is a year-round abundance of green aquatic plant life.

As best I remember, the bluegill and shellcrackers were the same color there as here.
