Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 28.0 range ? - ? cm
Max length : 45.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 86798); common length : 31.8 cm TL 雄魚/尚未辨別雌雄; (Ref. 12193); 最大體重: 3.1 kg (Ref. 4699); 最大年齡: 9 年 (Ref. 12193)
Inhabits lakes, ponds and pools of small to large rivers (Ref. 5723, 86798). Occurs at depths <14 m (Ref. 120827). Juveniles feed on small invertebrates such as cladocerans, copepods, and midge larvae. Adults are piscivorous, consuming shad, silversides, and occasional young sunfish (Ref. 10294). Spawns near the surface (Ref. 120818).
出現在小型到大型河川的湖，池塘與水池。 (參考文獻 5723,10294) 稚魚吃小型無脊椎動物例如水蚤，橈腳類的動物與蚊仔魚。 成魚是以魚為食又啃食非魚類，銀漢魚與偶然的幼魚翻車魚。 (參考文獻 10294)

50 = 0.5781 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00607 - 0.01980), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
營養階層 (Ref.
69278): 4.0 ±0.68 se; based on food items.
Generation time: 2.2 (1.9 - 4.6) years. Estimated as median ln(3)/K based on 13
growth studies.
回復力 (Ref.
120179): 中等的, 族群倍增時間最少 1.4 - 4.4年 (K=0.23-0.73; tmax=9).
Fishing Vulnerability (Ref.
