| Abstract: | The growth rate of grass carp fed with hybrid napier was found to be nearly three times the growth attained with Hydrilla and about five times the growth attained with Ceratophyllum. The gross conversion ratio on fresh weight basis with hybrid napier was on average 26.99 : 1, while with Hydrilla and Ceratophyllum it was 93.98 : 1 and 128.43 : 1 respectively. The average net production of grass carp fed on hybrid napier worked out to 1579.3 kg/ha in 182 days. |
