North America: St. Lawrence - Great Lakes, and Mississippi River basins from southern Quebec to Minnesota and south to Gulf; Atlantic and Gulf drainages from North Carolina to Florida and to northern Mexico. The species has been introduced widely as a game fish and is now cosmopolitan. Several countries report adverse ecological impact after introduction.
北美洲: 聖勞倫斯河-五大湖區,哈得遜灣 (紅河) 與密西西比河流域; 來自北卡羅萊那州到佛羅里達與到墨西哥北部的大西洋的流域。 此魚種已經廣泛地被引入作為一個遊釣魚類而且是現在世界的。 引入後的一些國家報告不利的生態衝擊。

生物学特性     字汇 (例如 epibenthic)

Inhabit lakes, ponds, swamps, and backwaters and pools of creeks, and small to large rivers (Ref. 86798). Usually found over mud or sand and common in impoundments (Ref. 5723). They prefer quiet, clear water and over-grown banks. Adults feed on fishes, crayfish and frogs; young feed on crustaceans, insects and small fishes. Sometimes cannibalistic. They don't feed during spawning; as well as when the water temperature is below 5°C and above 37°C (Ref. 30578). Builds nest at 25 mm-203 mm deep (Ref. 1998). An introduced species in Europe reported to avoid fast-flowing waters and to occur in estuaries with a salinity up to 13 ppt (Ref. 59043). Popular game fish in North America. Preyed upon by herons, bitterns, and kingfishers (Ref. 1998). Excellent food fish (Ref. 1998).

栖息于清澈的, 长满植物的湖泊,池塘,沼泽。 也在小溪的洄水区与水池与河中.(参考文献 5723) 偏爱安静,清澈的水域与生长过度的浅堆。 成鱼吃鱼,小龙虾与青蛙; 幼鱼捕食甲壳动物,昆虫与小鱼。 有时同类相食的。 在产卵的时候不进食; 以及当水温在 5 °C 与上方 37 °C 之下的时候.(参考文献 30578) 在北美洲的受欢迎的游钓鱼类。 被苍鹭,鹭鸶与鱼狗捕食了。 (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 which becomes aggressive and territorial builds the nest on muddy bottoms of shallow water. A female may spawn with several males on different nests. The male guards and fans the eggs for about 29 days (Ref. 93240). Spawning takes place spring to summer or when temperature reaches 15°C. Adults mate between the age of 5-12 years (Ref. 11243). Also Ref, 88808).北美洲: 聖勞倫斯河-五大湖區,哈得遜灣 (紅河) 與密西西比河流域; 來自北卡羅萊那州到佛羅里達與到墨西哥北部的大西洋的流域。 此魚種已經廣泛地被引入作為一個遊釣魚類而且是現在世界的。 引入後的一些國家報告不利的生態衝擊。
