The feeding patterns with respect to quality and quantity of food of silver barb, Barbodesgonionotus varied with their size and development. The results indicated that the fish inthe size group I (7-25 mm TL) were fairly omnivore with particular liking for rotifera,green and blue-green algae while the size group II (25.1-44 mm TL) and III (44.1-55 mmTL) were omnivore with higher tendency of feeding on debris, aquatic plants, greenalgae, blue-green algae and rotifera. However, the fish of the size group IV (55.1-80 mmTL) were found to be herbivore with feeding preference for aquatic plants, green andblue-green algae. In all the size groups, debris was the most dominant food item. Feedingpreference of the fish showed clear ontogenetic shift. The electivity indices revealed thatthe fish were selective feeder.
