Remarks | A pelagic, lacustrine species, forming very large schools (Ref. 188, 36901, 121343). The juveniles tend to stay closer to the shore than those of 5 cm standard length or more (Ref. 188). They appear to spend daylight hours at a depth of 70-95 m, rising up to 8-15 m at night, especially on dark nights (Ref. 188, 36901). These migrations reflect also the plankton migration (Ref. 36901). It feeds on plankton (Ref. 36901, 93960, 121343, 121352), like prawns, shrimps, also copepods, chironomids, diatoms and algae (Ref. 188). |
