生物學特性     字彙 (例如 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).

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).東大西洋: 距離海岸南方挪威到摩洛哥, 包括地中海與黑海.(參考文獻 2804, 參考文獻 51442) 在熱帶水域的它的發生的記錄是以誤鑑為依據.(參考文獻 3573)
