Around 1980 we fished one were you weighed in at guntersville. 20 fish back then as opposed to 7 now. Best I remember 22 pounds won. We had black ones caught near goose pond and that’s wheHarry Stressel or whatever his name was told me that the black ones would eventually take over as the grass spreads. The biologists that was there told the sure fire way to tell the difference. But 99 times out of 100 I always thought you could tell by looking at them
