Abstract
Puntius sophore has been studied for its morphometric relationship to food types (phytoplank-ton and zooplankton). It was observed that the mouth area of the fish did not show significant correlation to food types. The gut analysis suggested that it feeds on both food types with large portion of zooplankton at a later stage. On the basis of gut content corresponding to total length of the fish, the food habit of P. sophore has been grouped into three total length categories as category I or herbivorous (TL, 5.0-7.0cm), II or omnivorous (TL, 5.0-7.0cm) and III or omniv-orous with more tendency towards zooplankton (TL, 7.6-8.5cm). The F test showed significant differences for Relative Gut Length (p
