生物学特性     字汇 (例如 epibenthic)

Adults inhabit large, turbid rivers and eutrophic lakes, brackish coastal lakes and estuaries. Feed mainly on gregarious, pelagic fishes. They attain first sexual maturity at 3-10 years of age, usually at 4. Undertake short spawning migrations. Individuals foraging in brackish water move to freshwater habitats. Migrations up to 250 km have been recorded. Homing is well developed, even nearby populations may be relatively isolated. Spawn in pairs at dawn or night. Spawning occurs in April-May, exceptional from late February until July, depending on latitude and altitude when temperatures reach 10-14° C on spawning grounds (Ref. 59043). Popularly fished by sport fishers. Its flesh is succulent (Ref. 30578). Utilized fresh or frozen and eaten steamed, broiled and microwaved (Ref. 9988). An individual weighing 19 kg was reportedly caught in 1959 in Starnberger, Bavaria, Germany (Peter Admicka, pers. Comm. E-mail: peter.adamicka@oeaw.ac.at).

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | | 孕卵数 | 仔鱼

The spawning places are over gravel in moving water (Ref. 205). "Males are territorial and excavate shallow depressions about 50 cm in diameter and 5-10 cm deep in sand or gravel, or among exposed plant roots on which eggs are deposited, usually in turbid water and at 1-3 m depth. Spawn in pairs, at dawn or night. The female remains over the nest while the male circles rapidly around, at about 1 meter from the nest. Then male takes a vertical orientation and both swim around swiftly, and eggs and sperm are released, The female leaves the nest after all eggs are released. The male defends the nest and fans the eggs with his pectorals. Females spawn once a year, laying all the eggs at one time (Ref. 88075). Feeding larvae are positively phototactic and feed on pelagic organisms after they leave the nest for open water" (Ref. 59043).
