| 意見 | Found chiefly in rivers and streams, also man-made and natural lakes (Ref. 188); also in estuaries and lagoons (Ref. 188, 2683). Apparently able to tolerate moderate or even quite high salinities (Ref. 188). It forms enormous shoals in both inshore and offshore regions of Lake Kainji (Ref. 3034). It feeds on terrestrial and aquatic insects, but also ostracods and entomostracans; stomachs containing clupeid fish scales may represent cannibalism (Ref. 188). |
