Food Composition and Feeding Intensity of Channa Striata from Selected Stations of River Krishna, Andhra Pradesh

Abstract

Aim of the current piece of work was to study the food composition and feeding intensity of     Channa striata from Krishna river from June, 2019 to July 2020. The gut contents   were analysed from the three stations to undertaken the food composition of the fish. The major components of food items in the gut of fish was: fishes and their larvae, crustaceans, insect larvae, annelids with semi digested material and unidentified items. Fishes are identified as of teleost, particularly carps and cat fish larvae but most of the fishes leftovers could not be recognized since they are found in advanced phases of digestion with only scales & skeleton remains. Gastropods are identified as polycheate larvae, and Crustaceans are prawn and  crab larvae. The percentage occurrence of fishes and their larvae in gut contents and also feeding intensity were indicated that   C. striata preferential food  was fishes followed by crustaceans.
