Inhabits lakes, ponds, pools of creeks, and rivers. Also found in brackish water and in salt lakes. Most commonly found in clear water near vegetation; tends to shoal near the shore during spring (Ref. 9988, 10294). Feeds on immature insects, larger invertebrates, fishes and fish eggs during the day. Preyed upon by fishes and birds (Ref. 1998). Spawns between February and July in the northern hemisphere and between August and October in the southern hemisphere (Ref. 10999). Neither anterolateral glandular groove nor venom gland is present (Ref. 57406). Marketed fresh or frozen; eaten pan-fried, broiled or baked (Ref. 9988).
栖息于湖，池塘，小溪的水池与河。 也发现于半淡咸水与在盐湖。 最普遍发现于在植物附近的清澈的水域; 倾向在海岸附近的浅滩春天时。 (参考文献 9988) 吃不成熟的昆虫，较大的无脊椎动物，鱼与鱼卵在白天期间。 被鱼与鸟捕食了。 (参考文献 1998) 在北半球中在二月与七月之间与在八月与十月之间产卵在南半球.(参考文献 10999) 既不是前外侧的腺凹槽也不是毒液腺存在.(参考文献 57406) 生鲜或冷冻地在市场上销售; 吃油锅炸的, 火烤的或烧烤。 (参考文献 9988)

50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00920 - 0.01501), b=3.05 (2.98 - 3.12), in cm total length, based on LWR estimates for this species (Ref.
93245).
营养阶层 (Ref.
69278): 3.7 ±0.2 se; based on diet studies.
Generation time: 3.7 (3.3 - 4.8) years. Estimated as median ln(3)/K based on 43
growth studies.
