I fish a small mud hole, that has some big bass in it(8-11bs). No trout and a very limited crawfish population from what I have seen/looked for. There is bluegill, crappie, and bullheads, along with bass.
Pretty sure the bass get big from eating bullhead catfish. Not that the bluegill and crappie do not help but these bulls are always small but heavier/bigger than the gills and crappie. Plus the spines are not that pronounced, so they seem very easy to eat, while having much more mass than a crappie or bluegill.
Would really like to see some sort of calorie/protein/fat count for similar size bluegill, crappie, bullheads, pikeminnows, shiners, chubs etc.
