End Date: 00-05-1980

Program Area: Variety and Species

Commodity: Crab

Objectives:

To conduct the experiment on the seasonal patterns of feeding of fry and fingerlings

Methodology:

For the present study the fishes were collected once in every month from June 1979 to May 1980 from a pond of Bangladesh Agricultural University campus, Mymensingh. The collections were made randomly around the pond with the help of cast net having 0.25 inch mesh size. Immediately after collection tbe fishes were killed by preserving them in 10% formalin. Stomach contents of 81 fishes measuring 40 mm to 146 mm in total length were examined both by points method and percentage of frequency of occurrence method as outlined by Dewan and Sa ha (1979).
