Food and feeding habit of Bele Glossogobius giuris (Hamilton and Buchannan, 1822) Collected from Mithamain Haor of Kishoreganj districts, north- eastern Bangladesh

Abstract

In the present study, an attempt has been made to investigate the food and feeding habits of the Bele Glossogobius giuris from Mithamoin Hair, Kishorgonj, Bangladesh. Fish specimens were collected monthly from March 2014 to February 2015. During this study 252 specimens were collected. On the basis of qualitative and quantitative analysis of gut contents, G. giuris has been categorized as carnivorous. Food items mainly consist of fish, crustaceans, insects, zooplankton and algae. The main food items in guts were recorded as; fishes (46.7, 53.181%), Insects (3.6, 2.050%), Crustacean (16.2, 14.535%), zooplankton (3, 1.216%), algae (0.5, 0.162 %) by volume and occurrence. The mean value of Gastrosomatic index (GaSI) and active feeding were found to be maximum 3.08 and 0.56 in February 2015 and minimum 1.50 and 0.32 in October 2014 respectively. Highest Gastrosomatic Index and Active feeding occurred during winter (February) prior to breeding season started and lowest Gastrosomatic Index value as well as poorer active feeding occurred during the breeding season.
