I'm not an expert Jeff, but I've been keenly observing gambusia for many years. I think Burg is right. Gams are not great bait. Although I have caught many bream, bass, and crappie on gams, they prefer other bait to them. I do not like them as a primary forage species, but I think diversity is important. They are better survivors than fatheads, but that isn't saying a lot. I have never seen an over population of gams. I have always noticed them in pods of 100 or fewer... usually much fewer. Their legendary mosquito control is mostly myth. They're superior to small bream only in shallow ditches where bream can't survive. Bream are much quicker and eat a lot more. I think egg eating is a little overblown. Bream and bass lay their eggs where gambusia will never go. If they go near a nest, they're instant lunch. Fatheads lay eggs in gam territory, but they are fiercely protective of their eggs. I'm sure the gams get some of the FH eggs, but so do BG.
