簡短描述
檢索表 | 型態特徵 | 形態測量圖
Big mouth, upper jaw extend trailing edge of eye. High body, side flat, backside with ridges. Anomalistic macula and dark spots on the sides; 4-5 dark horizontal stripes near the base of dorsal fin (Ref. 85820).
Adults inhabit rivers (Ref. 26334). Are demersal piscivores which have very specialized feeding habits--as soon as they start feeding, they feed solely on fry of other fish species. Typical of stalking predators, they rely on vision for following the movement of prey before leaping forward and snapping at the victim. Prey consist mostly of diurnal fishes whose eyes have color vision and high acuity but cannot function at night. The habitat of the Chinese perch is usually rich in macrophytes and might be very turbid during rainy season (Ref. 28033).
棲息於河。 (參考文獻 26334) 已經非常特殊化的一個底棲的魚食性食性--當它時開始進食, 它只吃其他魚種的魚苗。 典型的悄悄靠近掠食者，它為在跳躍向前地而且咬住受害者之前跟隨獵物的運動仰賴視野。 它的獵物日行性魚大部份組成 , 眼有色彩視野與高的銳敏但是不能夠運作在晚上。 季花魚的棲息地通常是豐富的在大型植物而且可能在雨季的時候非常混濁.(參考文獻 28033)
