Abstract

The food, feeding biology and the morphology of associated organs of a tropical catfish, Mystus
nemurus C. & V. were studied for one year. A total of 267 specimens of M. nemurus C. & V. were examined.
Results indicate that they are usually euryphagous, feeding extensively on a wide variety of food
items in the bottom substrate of the reservoir. This is clearly reflected in the morphological and anatomical
characteristics of various organs concerned with feeding. Adult specimens feed predominantly on
teleosts followed by crustaceans and insects. Aquatic vegetations and detritus are swallowed as accidental
food items. Feeding intensify as they approach size of first maturity. Relative gut indices change
insignificantly from young of year to adult stage and are insignificant (p > 0.05). Symptoms of gastric
regurgitation were not evident.
