Abstract
Abstract Repopulation by longear sunfish of stream segments decimated by electrofishing was studied in six areas on four streams in Louisiana. Lepomis m. megalotis (Rafinesque) repopulated the decimated areas to a level as great or greater (3.5 times) than the biomass of the decimation sample at four of the six areas within one year. Repopulation occurred between March and late summer and was accomplished by fish at least two years old. A principal factor allowing rapid repopulation of longear sunfish in the decimated segments may have been an apparent lack of repopulation by large predatory species.
