Food habits of Oxygaster bacaila (Ham.) from Kaptai Lake, Bangladesh
Gut contents of 120 Oxygaster bacaila fmm Kaptai Lake were studied. Index ofpreponderance (IP) indicated that 0. bacaila consumed highest amount of Insects(35.89%) and thus occupied the first position among the food items. Zooplankton(Rmifera and crustacea 31.79%) and the other food items found in the guts were algae(Chlorophyceae, Bacillariophyceae, Euglenophyceae and Cyanophyceae 24.51%). Fromthe analysis of gut contents, this fish might be considered as omnivore as it consumedboth animal and plant foods with higher preference for animal food. The feedingintensity of this fish is fairly high. Total length (TL) versus gut length (GL) relationshipand their ratio were found to be GL = 0.57663 TLL04801 (r = 0.9963) and TL: GL = l:0.7086 respectively.
