Effect of Vermicompost as Pond Fertilizer on Growth Performance of Cirrhinus mrigala (Ham.)

Fertilization of organic manure and provision of supplementary feed with additives such as mineral and vitamin premix has a positive influence on the growth of Indian major carps that contributed to high fish production. An experiment was conducted to study the effect of different doses of fertilizer i.e Vermicompost @15,000kg/ha/yr ,vermicompost @10,000 kg/ha/yr, vermicompost @5,000 kg/ha/yr and cowdung @ 10,000 kg/ha/yr on the growth of Cirrhinus mrigala. The response of treatments towards increase in fish weight and total length was significantly different. The fertilizers of ponds enhanced the gross fish yield / pond / 5 months from that of the observations of control experiment. Increase in body weight of mrigal was maximum in vermicompost @10,000 kg/ha/yr. While the poor increase in body weight was observed in control.
