生物学     用語集 (例 epibenthic)

Adults are pelagic occurring near shore, entering lagoons and lower reaches of rivers in schools; often in polluted waters (Ref. 51442, 59043) between temperatures 8-24°C. Juveniles colonize the littoral zone and estuaries (Ref. 51442). Adults feed on epiphytic algae, detritus and small benthic or planktonic organisms, pelagic eggs and larvae while juveniles feed on zooplankton until about 3.0 cm SL, then on benthic animals and plants (Ref. 59043). Spawning takes place at sea near the coast between September and February (Ref. 30578, 51442). Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Adults undergo migrations (Ref. 51442).

Life cycle and mating behavior 成熟 | 繁殖 | 放精 | | 生産力 | 幼生

Spawning takes place at sea near the coast by gathering in groups between September and February (Ref. 51442). The eggs develop at sea (Ref. 51442). The juveniles then colonize the littoral zone and the estuaries (Ref. 51442). Adults enter the lower parts of the rivers and treturn to the sea to spawn (Ref. 51442).
