生物学特性     字汇 (例如 epibenthic)

Inhabits algal and seagrass flats and shallow lagoon and coastal reefs (Ref. 9710, 11230). Forms schools. Mainly diurnal. Juveniles feed on filamentous algae, adults feed on leafy algae and seagrasses (Ref. 9710). Commercially cultured in Japan. Commonly found in large estuaries (Ref. 9002). Anterolateral glandular groove with venom gland (Ref. 57406).

栖息于海藻平台与海草平台与舄湖浅滩与岸礁。 (参考文献 9710,11230) 形成鱼群。 主要日行性。 稚鱼吃菌丝藻, 成鱼吃叶状的藻类与海草。 (参考文献 9710) 商业地在日本养殖。 普遍地栖息于大的河口。 (参考文献 9002) 用毒液腺的前外侧的腺凹槽.(参考文献 57406)

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

In Belau, ripe individuals form prespawning congregations of 30-60 individuals in shoal areas of inner reef flats; spawning occurs on the 4th or 5th day of the new moon; spawning sites are near reef edge. About 300,000 eggs/female at a single spawning. Individuals that spawn in consecutive yrs. & that 2+ yr. class fish could spawn more than once in a single season. Aug (Ref 1754) in Belau. 西太平洋: 韓國南部,日本南部,?小笠原群島,台灣,中國南部,馬來西亞,新加坡,泰國,安達曼群島,印尼,菲律賓,雅普島,帛琉,波納佩島 (加羅林群島) ,索羅門群島,巴布亞新幾內亞,萬那度,新加勒多尼亞與澳洲。 時常被誤鑑成 Siganus canaliculatus 。 (參考文獻 2334)
