Do you love big bluegill?
Regarding Black Coloring of Crappie being Male only in the pre spawn/Spawn stage , here is a quote from ,'In-Fisherman Critical Concepts 2 ;Crappie Location ': "Crappies turn dark to absorb maximum sunlight .The heating process then keys their metabolism for greater feeding and quicker egg maturation . Some anglers suppose that only Males turn coal black".
Amazing adaptation I'd say! Apparently both sexes turn black.Could this be at all true of Bluegills and other fish?
