简单描述

Commonly found in lakes and rivers (Ref. 9258). Inhabits stony rivers (Ref. 9072). Migrates to the sea to breed. Oviparous (Ref. 205). Marketed fresh, smoked and frozen; eaten fried and broiled (Ref. 9988). Reports of reaching up to 2 meters and 50 kilograms are rare and more common historically; in recent times, only a few exceed 120 cm TL (Ref. 82796).
普遍地栖息于湖与河。 (参考文献 9258) 栖息于多石河。 (参考文献 9072) 回游到海洋繁殖。 卵生的.(参考文献 205) 在市场上销售生鲜、烟熏与冷冻; 油炸后食用与火烤的.(参考文献 9988)
