A study was undertaken to attempt all possible crosses among four species of centrarchids, representing four distinct genera, by artificial stripping and fertilization. The species used were Micropterus salmoides (Lacépède), the largemouth bass; Chaenobryttus gulosus (Cuvier), the warmouth; Lepomis macrochirus Rafinesque, the bluegill; and Pomoxis nigromaculatus (LeSueur), the black crappie. Hybridization success was used as an indication of the phylogenetic relationship of the parental species.
