Abstract

Understanding the interspecific relationships for proper management of an ideal fishery system, food, and feeding habits of fishes are prerequisites. The food and feeding habits including types and amount of feed and seasonal pattern of feeding were studied. 168 Aspidoparia morar were collected from the River Padma, Rajshahi, Bangladesh from May to December, 2011. The relationship between total length and alimentary canal length was tested using OLS regression. Qualitative as well as quantitative analyses of stomach and gut contents of each fish were done by percentage of occurrence and point method and fullness of stomach was measured by fullness index method. Aspidoparia morar was omnivorous due to the presence of both phytoplankton (Chlorophyceae, Euglenophyceae, Bacillariophyceae, Cyanophyceae) and zooplankton (Rotifera, Crustacea) in the gut content. Based on the point method, the average percentage of phytoplankton and zooplankton was 80.71% and 19.29%, respectively. The highest average percentage of fullness was 72.62% in October whereas the lowest was 56.55% in December. The highest average percentage of emptiness recorded was 43.45% in December and the lowest was 27.38% in October. Total length was found statistically positively significant (P<0.01 with the alimentary canal length. Overall, the article concludes that Aspidoparia morar is an omnivore with a higher feeding preference for phytoplankton and the food habits change with the seasons based on the qualitative and quantitative analysis of food.

Keywords: Food and feeding habit, fullness of stomach, emptiness of stomach, feeding intensity, plankton
