Impact of de-silting of pond on the growth and survival of catla (Catla catla) spawn.
Experiments were conducted in non-desilted and de-silted earthen nursery ponds for a period of fifteen days to evaluate the growth and survival of Catla spawn. The fry attained an average weight of 42.03 +/- 0.36 and 74.36 +/- 72 mg, with a survival rate of 23.44 +/- 0. 31 and 50.91 +/- 0.21% in non-desilted and de-silted ponds respectively Mentioned length data also indicate that growth and survival of Catla spawn was significantly higher in de-silted ponds.
