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。

生物學特性     字彙 (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).

棲息於清澈的, 長滿植物的湖泊,池塘,沼澤。 也在小溪的洄水區與水池與河中.(參考文獻 5723) 偏愛安靜,清澈的水域與生長過度的淺堆。 成魚吃魚,小龍蝦與青蛙; 幼魚捕食甲殼動物,昆蟲與小魚。 有時同類相食的。 在產卵的時候不進食; 以及當水溫在 5 °C 與上方 37 °C 之下的時候.(參考文獻 30578) 在北美洲的受歡迎的遊釣魚類。 被蒼鷺,鷺鷥與魚狗捕食了。 (參考文獻 1998) 優良的食用魚.(參考文獻 1998)

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

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。
