生物学     用語集 (例 epibenthic)

Prefers cooler waters (Ref. 52193), occurring in small groups and shoals, in various habitats from small streams to large rivers and lakes (Ref. 52193). Frequently associates with cover or shelter such as fallen logs, brushwood or marginal vegetation (Ref. 52193). It feeds on insects, zooplankton, seeds, green algae and diatoms. Oviparous (Ref. 205). Breeds during summer when rivers are swollen after rain and lays adhesive eggs amongst vegetation. Is preyed upon by larger fishes and birds (Ref. 7248 & 5214).
