The Food and Feeding Habits of Phractolaemus anosrgii (Boulenger) from Warri River, Nigeria

O. ODUM, M ANUTA

Abstract




The food and feeding habits of Phractolaemus ansorgii (Boulenger) obtained from the Warri River, Nigeria are discussed. The main food items were detritus, algae, dominated by the Bacillariophyceae and sand grains. The feeding habits varied seasonally and with fish size. The fish fed more actively in the dry season while diet diversity decreased with increased size. It is argued that as fish grew older, it became more specialized in its dietary habits.
