- Feeding habits of the African bagrid, Chrysichthys filamentosus in a Nigerian lake.
説明
The feeding ecology of Chrysichthys, a commercially important freshwater bagrid in Nigeria, is described from a southeastern lake. Over a year period, 779 stomachs were examined. The main food items were chaoborid and chironomid larvae, ostracods, copepods and detritus. Larger fish fed mostly on insect larvae and detritus while the smaller individuals consumed mostly microcrustacea. Feeding intensity was lowest during the height of the flood. There was little diel change in the amount of food consumed. The fish are morphologically pre-adapted for their benthic omnivorous feeding habits.
