A cool-water species not found below 600m altitude; occurs in deep pools and flowing waters of permanent rivers and in dams (Ref. 52193). It feeds primarily on algae in winter months and aquatic insects in summer months, but also takes mussels, snails, crabs and small fish (Ref. 52193). Breeds during spring and summer, males maturing at a smaller size (170 mm FL) than females (300 mm FL); females grow larger than males (Ref. 7248, 52193).
一個冷水魚種不在 600個公尺高度之下發現。 出現於永久性河川的深水池與流動水域與在水壩中。 主要吃藻類 (冬天數個月), 也捕食貽貝,蝸牛,螃蟹與小魚。 在春天與夏天期間進行繁殖, 超過雌性 (30 公分 FL) 雄姓在較小的體型 (17 公分 FL) 時成熟. 雌性生長大於雄性。 (參考文獻 7248) 為人類的一個食用魚.(參考文獻 4537)
