Abstract
The feeding preferences
of Gudusia chapra, locally known as ‘Chapila’, collected from
the open water sources of the Pagla River, a tributary of the Meghna River,
showed filter-feeding food habits rich in phytoplankton over zooplankton.
Altogether, 17 genera of phytoplankton belong to 4 groups; Bacillariophyta
(diatoms), Chlorophyta (green algae), Cyanophyta (blue-green algae), and
Dinophyta (dinoflagellates), and 5 genera of zooplankton belonging to 2 major
groups, Rotifer and Crustaceans, were examined in the stomach of Gudusia
chapra. Moreover, the total length of Gudusia chapra ranged between
44 mm and 130 mm, and the body weight ranged from 0.5 g to 20.2 g. The gonad
weight ranged from 0.0011g to 1.0758 g. The sex ratio of male to female Gudusia
chapra was found 1:1.12. The high gonado somatic index (GSI) value of Gudusia
chapra was observed in January for males (1.702) and in February
for females (5.966).
