The diets of r,edbreast sunfish (Lepomis auritus) and spotted sucker (Minytrema melanops) in the Satilla River, Georgia, were shown to be quantitatively different using Spearman rank correlation coefficients. The index of overlap of Pianka by number and weight showed considerable overlap in the diet during the fall. Chironomids were the main food component contributing to this overlap. The index of electivity of Ivlev indicated moderate to high selectivity by both species for chironomids in the winter, spring, and summer and some selectivity in the fall. The diet overlap between the 2...

Life history data were collected from Suwannee River and Okefenokee Swamp warmouth (Lepomis gulosus) from 19 July 1968 through 28 June 1973. Suwannee River warmouth became sexually mature in the third year of life. while warmouth from the Okefenokee Swamp became sexually mature in the second year of life. Collection of fecund warmouth suggested that the nesting season extended from April to late July or early August and that peak spawning generally occurred in early May. Fecundity estimates varied from 3,029 to 22,850 ova per female and generally increased with fish length. The average...
