簡短描述
型態特徵 | 形態測量圖
Head large; thick and fleshy lips; nostrils tubular. First dorsal fin high, with a strong serrated spine and 6 rays. Skin tough and smooth. Body coloration in adults vary from olive-green to brown, black or purplish dorsally and white ventrally. Urogenital papilla triangular in females; longer and cylindrical in males.
頭部大的; 厚而肉質的唇; 鼻孔管狀的。 第一背鰭很高, 具有一個強韌的鋸齒狀的棘與 6個鰭條。 皮膚強硬而平滑的。 身體顏色當成魚時改變從橄欖綠色的到褐色的﹐黑色的或帶紫色的背面與腹側白色的。 泌尿生殖器的乳突三角形的在雌性中; 比較長與圓筒形的在雄性中。
Adults inhabit slow moving streams, lakes and ponds with fringing vegetation. They swim close to sand or gravel bottoms. More abundant in lakes than in flowing water (Ref. 44894). Usually solitary but juveniles sometimes form loose aggregations. Mainly bottom-feeders (Ref. 44894). Feed on insect larvae, prawns, crayfish, mollusks, and small fishes. Breeding occurs between spring and mid-summer when water temperatures rise to between 20° and 24°C (Ref. 44894). Utilized for human consumption.
用岸邊的植叢成魚棲息於緩慢移動的溪流 , 湖泊與池塘。 他們游泳接近沙子或礫石底部。 更豐富的在湖中超過在流動的水.(參考文獻 44894) 通常獨居性的但是稚魚有時形成鬆散的魚群。 主要地底部-捕食者.(參考文獻 44894) 捕食昆蟲幼生，蝦，小龍蝦，軟體動物與小魚。 當水溫隆起到 20個 ° 與 24 °C 之間的時候，在春天與夏季中旬之間繁殖。 (參考文獻 44894) 供人類食用。
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Water temperature (20-24 °C) considered the primary spawning stimulus. There is direct pairing during spawning. Male builds nest (0.6-2.0 m in diameter) and cares for eggs in the nest up to 2 weeks. The nest is made of gravel and rocks with a central sandy depression in which the female deposits up to 20,000 eggs depending on her size (Ref. 5259). Eggs scattered into the rubble are tended and guarded by the male after the female departs (Ref. 205). Hatching occurs in 7-10 days at 18°C (Ref. 240).大洋洲: 澳洲的特有種。
