Habitat and Ecology [top]

Habitat and Ecology:	Habitat: Large, turbid rivers and lakes; in brackish coastal lakes and estuaries. Biology: Lives up to 12 years. Spawns for the first time at 3-4 years and 200-300 mm SL, females usually a year later than males. Spawns for about one month in April-May, at 10-22°C. Individual females may spawn 2-3 portions of eggs. May undertake short spawning migrations. Males are territorial and excavate shallow depressions in sand or gravel, or exposed plant roots on which eggs are deposited, usually along shallow shores at 1-2 m depth. Nests often close to nests of S. lucioperca. Most active at dusk and dawn, foraging on small fish and invertebrates. Larvae and juveniles pelagic, feeding on zooplankton.
Systems:	Freshwater
