生物學特性     字彙 (例如 epibenthic)

Inhabits vegetated lakes and ponds, as well as quiet pools of creeks and small rivers (Ref. 86798). Feeds on small fishes and other vertebrates (Ref. 1998), as well as fish eggs (Ref. 2058). Adtults rarely form schools but occur in pairs or loose aggregations of three to four individuals; young individuals aggregate in fairly large schools (Ref. 120693). An introduced species in Europe which avoids swift waters and occurs in estuaries with a salinity up to 18.2 ppt (Ref. 59043). Reported in Europe to prey on a wide variety of invertebrates (Ref. 59043). Considered undesirable catch (Ref. 30578).

出現於安靜與小溪與小河的長滿植物的湖泊,池塘與水池。 主要吃蠕蟲,甲殼動物與昆蟲 (參考文獻 7020) 也但是可能吃小魚與其他的脊椎動物 (參考文獻 1998), 以及魚卵.(參考文獻 2058) 被認為是不受歡迎的捕捉。 (參考文獻 30578)

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

Males build the nest on very shallow waters near the shore. The pair then swims in a circular path over the nest and eggs and sperm is released in intervals. The male guards the eggs for about 7 days (Ref. 93240) and the young (to about 11 days after hatching), then prepares the nest for another spawning with the same or different females (Ref. 1998). In European waters, each male may spawn with several females in one nest and guard the nest until abandoned by larvae (Ref. 59043). Produces up to 1000 eggs (Ref. 1672).北美洲: 到在美國的南卡羅萊那州的加拿大的新布蘭斯維克。 廣泛地引入。 引入後的一些國家報告不利的生態衝擊。
