Monthly weights (i.e. from July to December 2005) gained by C. catla with different feeds are
presented in Fig. 1. In the control group, the weight was 6.48 g, whereas the maximum with Feed-A
was 13.38 g. With Feed-B and Feed-C, the average growths were 11.56 and 9.05 g, respectively (Fig.
1). In the control group (feed without seaweed), the weight gain of the fish was relatively very low
for all the months as compared to the other feed types
