生物學特性     字彙 (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).

棲息於海藻平台與海草平台與潟湖淺灘與岸礁。 (參考文獻 9710,11230) 形成魚群。 主要日行性。 稚魚吃菌絲藻, 成魚吃葉狀的藻類與海草。 (參考文獻 9710) 商業地在日本養殖。 普遍地棲息於大的河口。 (參考文獻 9002)

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

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)
