Prey use of wetland benthivorous sunfishes: ontogenetic, interspecific and seasonal variation

Jacob W. Bransky, Nathan J. Dorn

Environmental Biology of Fishes > 2013 > 96 > 12 > 1329-1340

The intensity of competitive interactions between fishes is partly determined by prey use and ontogenetic niche shifts. In a wetland where distinct habitat shifts are missing we compared prey use of three generalist benthivorous sunfishes to look for evidence of ontogenetic, interspecific, and “seasonal” variation in prey composition. Diet analysis revealed evidence of diet ontogeny in warmouth (Lepomis gulosus...
