Repopulation of Experimentally Decimated Sections of Streams by Longear Sunfish, Lepomis megalotis megalotis (Rafinesque)

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