New York (Mitchill 1814).
Etymology/Derivation of Scientific Name
Morone flavescens Mitchill 1814:18.
Maximum size: 40 cm TL (Page and Burr 1991).
Coloration: Peritoneum silvery (Goldstein and Simon 1999).
Counts: Anal fin soft rays 6 to 8 (Hubbs et al. 2008
Mouth position: Terminal, slightly oblique (Goldstein and Simon 1999).
Body shape: Upper jaw extending to below the middle of eye or farther (Hubbs et al. 2008).
External morphology: Preopercle strongly serrate (Hubbs et al. 2008).
Internal morphology: No canine teeth (Hubbs et al. 2008). Intestine well differentiated; pyloric caeca thick (Goldstein and Simon 1999).
Distribution (Native and Introduced)
U.S. distribution: Introduced as game fish throughout much of North America; native range includes much of southern tier of Canada and the northern United States east of the Rocky Mountains (Hubbs et al. 2008).
Texas distribution: Introduced into many waters in the state; established breeding populations exist only in the Rio Grande near El Paso, in Meredith Reservoir on the Canadian River, and Greenbelt Reservoir on the Salt Fork of the Red River (Hubbs et al. 2008).
Abundance/Conservation status (Federal, State, NGO)
Currently Stable (Warren et al. 2000) in the southern United States.
Mesohabitat: Freshwater, rarely brackish waters; very adaptable species that lives in a variety of habitats; most common in clear, open water with moderate vegetation; occurs irregularly at depths greater than 10 m (Lee 1980).
Spawning habitat: May reproduce in clear water on submerged plants or, if not available, on other submerged items such as logs, gravel, and rocks (Simon 1999).
Spawning behavior: Nonguarder; open substratum spawner; phytolithophil – nonobligatory plant spawner that deposits eggs on submerged items, has late hatching larvae with cement glands in free embryos, has larvae with moderately developed respiratory structures, and has larvae that are photophobic (Balon 1981; Simon 1999).
Age at maturation:
Growth and Population structure:
Food habits: Invertivore/carnivore; main food items include immature insects, larger invertebrates, fishes and fish eggs (Goldstein and Simon 1999).
