Effect of Vermicompost on the Growth Performance of Indian Major Carps in Fish Rearing Pond

Different organic manures vermicompost @ 15000, vermicompost @ 10000, cow dung @ 10000, poultry manure @ 6000, pig manure @ 4000 kg/ha/yr and control used to monitored their effect on growth performance of Catla catla, Labeo rohita and Cirrhinus mrigala . The results revealed that all the three species gained maximum length in vermicompost @ 10,000 kg/ha/yr followed by vermicompost @ 15,000 kg/ha/yr, cow dung @ 10,000 kg/ha/yr, poultry manure @ 6,000 kg/ha/yr, pig manure @ 4,000 kg/ha/yr and control. Among the 3 species C. mrigala showed maximum increase in body length which was 33.4 cm followed by L. rohita and C. catla was 32.1, 31.3 cm in vermicompost @ 10,000 kg/ha/yr treatment. The minimum length of C. mrigala , L. rohita , C. catla observed in pond treated control. But in case of C. mrigala , the result revealed that the maximum increase in body length in vermicompost > poultry manure > cow dung > pig manure and control, respectively. All the three species gained maximum growth in vermicompost. Among the 3 species L. rohita showed maximum growth followed by C. catla and C. mrigala . There was two times more growth of Indian major carps in pond treated with vermicompost @ 10,000 kg/ha/yr as compared to control.
