Etymology: Micropterus:Greek, mikros = small + Greek,pteron = wing, fin (Ref. 45335); dolomieu:Named after M. Dolomieu, French minerologist and friend of Lacepède (Ref. 1998). Eponymy: Déodat Gratet de Dolomieu (1750–1801) was a French geologist. [...] (Ref. 128868), visit book page. More on author: Lacepède.
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. 北美洲: 聖勞倫斯河-五大湖區系統, 哈得遜灣與密西西比河流域從加拿大魁北克南部到達科塔北方部而且南至在美國的阿拉巴馬州北部與俄克拉荷馬州東部。 對於垂釣用魚引入許多國家中了。 引入後的一些國家報告不利的生態衝擊。

Adults inhabit 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). They are sometimes cannibalistic (Ref. 30578). Preyed upon by fishes and turtles (Ref. 1998). They build nest, usually at three or four feet deep (Ref. 120821). Excellent food fish (Ref. 1998).
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.
