生物学特性     字汇 (例如 epibenthic)

Adults occur in freshwater to estuarine conditions. Adults breed at sea; juveniles move into estuaries and enter rivers in late winter or early spring. Females remain in freshwater for 7 years, males for 4 years. Return to estuaries before maturing sexually prior to spawning. Oviparous, eggs are pelagic and non-adhesive (Ref. 205). Feed on benthic algae and small invertebrates over muddy bottom (Ref. 6465). Decline in population from obstruction, by dams and weirs, of free passage into rivers.

出现于淡水到河口的环境。 在海上繁殖; 稚鱼移进河口中而且在冬季末或在初春之际进入河。 雌性逗留在淡水的 7 年, 达 4 年的雄性。 在产卵之前性成熟之前回到河口。 吃在泥底部上的水底藻类与小型无脊椎动物。 (参考文献 6465) 从障碍族群减少,藉着水坝与鱼梁, 分离通道进入河之内。

Breed at the sea throughout the year. Juveniles move into estuaries and enter rivers usually in late winter or early spring. Males remain in freshwater until 4 years, females for up to 7 years. Fish return first to estuaries before maturing sexually prior to spawning (Ref. 7248).非洲: 到科西灣 (南非) 的東海岸的河口與河從肉湯河.
