Abstract

The present study was carried out to analyze the gut contents of Indian major carp Rohu (Labeo rohita) from Meeranpur Lake of district Sultanpur, Uttar Pradesh, India. Monthly samples were collected from the lake for the analysis of gut contents during August 2018 to July 2019.The analysis of gut contents of Indian major carp, L. rohita provides information on quality and quantity of food components and feeding habit of fish. The results so obtained were used to compute percentage volume of food items in the gut (% Vi), percentage of occurrence of guts having particular food items (% Oi), Index of preponderance and the grading of food items of gut contents of L. rohita. Under natural condition the fingerling stage of L. rohita prefers zooplankton with phytoplankton as subsidiary food. The fingerling stage of the fish exhibited a strong positive selection for all zooplanktonic organisms and smaller phytoplankton. The adult stage of L. rohita show a strong negative selection for all zooplanktonic organisms and positive selection for most phytoplanktonic organisms and submerged macro vegetation. The present study agreed that the Indian major carp L. rohita exhibits different feeding strategy during its growth from fingerling to adult.
