Adults occur in pools and sluggish runs over soft substrates in creeks and small to large rivers. Also found in impoundments, lakes, and ponds (Ref. 86798). They rarely enter brackish waters (Ref. 1998). They are nocturnal feeders that feed on mollusks, insects, leeches, crayfish and plankton, worms, algae, plant material, fishes, eggs of least cisco, herring and lake trout (Ref. 1998). Juveniles (3-6 cm) feed mostly on chironomid larvae, cladocerans, ostracods, amphipods, bugs and mayflies (Ref. 1998). Can tolerate high carbon dioxide and low oxygen concentrations and temperatures up to 31.6 °C although experiments show upper lethal temp. to be 37.5 °C; resistant to domestic and industrial pollution (Ref. 1998). They have been observed to bury itself in mud to escape adverse environmental conditions (Ref. 1998). Prepared hot-smoked and also cooked in various ways (Ref. 1998).
ライフサイクルと交尾行動 成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
Nests are built by one or both sexes. After a period of caressing each other with their barbels, male and female settle over the nest, face opposite directions (while maintaining body contact) and spawn. Although eggs are cared for by one or both parents, there have been reports of parents eating their own eggs. Caring entails fanning by the paired fins, moving and stirring by the barbels, and may be picked up and ejected from the mouth; this ensures hatching.
