Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

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).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01413 (0.01064 - 0.01875), b=3.00 (2.91 - 3.09), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trofisch niveau (Ref. 69278): 4.5 ±0.80 se; based on food items.

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (tm=1-2).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100).

Prijsklasse (Ref. 80766): Unknown.
