簡短描述
檢索表 | 型態特徵 | 形態測量圖
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).
普遍地棲息於湖與河。 (參考文獻 9258) 棲息於多石河。 (參考文獻 9072) 迴游到海洋繁殖。 卵生的.(參考文獻 205) 在市場上銷售生鮮、煙燻與冷凍; 油炸後食用與火烤的.(參考文獻 9988)
