Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 29.5, range 22 - ? cm
Max length : 71.0 cm FL 雄魚/尚未辨別雌雄; (Ref. 6390); common length : 35.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 2158); 最大體重: 4.0 kg (Ref. 6390); 最大年齡: 24 年 (Ref. 95598)
Adults favor estuarine (including mangroves), rocky reef and inshore, coastal water habitats (Ref. 5962, 27248). They flourish in seagrass areas (Ref. 6390). Ludericks are moderately sedentary, schooling fish. They are herbivorous and feed primarily on seagrasses (Ref. 6390). Filamentous algae (Ref. 26966) and cabbage weed also form part of their diet (Ref. 28607). Marketed as fresh fish (Ref. 10384).
他們喜歡河口的 (包括紅樹林) 又岩石的礁與沿海地區，海岸水域棲息地。 (參考文獻 5962,27248) 他們在海草區域中活躍。 (參考文獻 6390) Ludericks 是一般定棲又群游性魚。 他們是食草的而且主要捕食海草。 (參考文獻 6390) 菌絲藻 (參考文獻 26966) 與捲心菜雜草也形成部分的他們的食性。 (參考文獻 28607) 在市場上新鮮銷售魚.(參考文獻 10384)

Maturing luderick form large aggregations. Mature fish undertake 'runs' from inside the rivers and coastal lakes to the sea. The fish spawn in the surf zone and estuary mouths (Ref. 6390).西太平洋: 澳洲東南部 (對澳洲南部的昆士蘭南部) 與紐西蘭。
