North America: St. Lawrence-Great Lakes system, Hudson Bay (Red River) and Mississippi River basins from southern Quebec in Canada to North Dakota and south to northern Alabama and eastern Oklahoma in the USA. Introduced into many countries for sport fishing. Several countries report adverse ecological impact after introduction.

生物学特性     字汇 (例如 epibenthic)

Inhabits shallow rocky areas of lakes and clear and gravel-bottom runs and flowing pools of rivers (Ref. 86798). Young feed on plankton and immature aquatic insects while adults take in crayfish, fishes, and aquatic and terrestrial insects (Refs. 1998, 10294, 44091). Is sometimes cannibalistic (Ref. 30578). Preyed upon by fishes and turtles (Ref. 1998). Builds nest, usually at three or four feet deep (Ref. 120821). Excellent food fish (Ref. 1998).

栖息于湖,河的清澈而砾石底小支流与细流水池的水浅岩石区,寒冷又流动的溪流与此溪流注入的水库。 幼鱼捕食浮游生物与不成熟的水生昆虫虽然成鱼接受小龙虾,鱼与水生与陆栖的昆虫 (参考文献。 1998; 44091)。 某一个时间同类相食的.(参考文献 30578) 被鱼与海龟捕食了。 (参考文献 1998) 优良的食用鱼.(参考文献 1998)

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | | 孕卵数 | 仔鱼

The male builds the nest in shallow waters of lakes and rivers, on sand, gravel, or rocky bottoms. Nest building usually occurs within 150 yards of where his nest was built in previous years. The pair swims about the nest, rubbing and nipping each other and eventually come to rest on the bottom. Actual spawning occurs and lasts for 5 seconds. The pair then encircles the nest for about 25-45 seconds, before settling to spawn again. This goes on for 2 hours. After spawning, the female leaves the nest and may spawn with another male in another nest. Males guard the eggs and young.

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00897 - 0.01340), b=3.05 (2.99 - 3.11), in cm total length, based on LWR estimates for this species (Ref. 93245).
营养阶层 (Ref. 69278):  3.6   ±0.2 se; based on diet studies.
Generation time: 6.8 (5.2 - 7.3) years. Estimated as median ln(3)/K based on 26 growth studies.
回复力 (Ref. 120179):  中等的, 族群倍增时间最少 1.4 - 4.4年 (K=0.10-0.28; tm=3-6; tmax=14; Fec=5,000).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100).
