Abstract
The study was conducted to assess the growth and feed performance of 3 fish species viz. Big head carp, Grass carp and Silver carp in cage in pond based system from September 2015 to January 2016 upto 136 days. The fish species i.e. Big head carp, Silver carp and Grass carp were stocked in 2:1:2 ratio, 100 in each 4 cages. Fishes in cage 1 and 2 were supplied with the ordinary feed prepared at lab having mustard oil cake and rice bran at 1:1 ratio. Similarly cages 3 and 4 were supplied with formulated feed (Him feed) on the basis of their 3% body weight for the first month and 2% body weight from second till harvest. Water quality parameter analysis was done on weekly basis and fish growth measurement was done on monthly basis. Total harvest weight from the four cages was 1.5 kg out of which 0.160 kg was from fish species fed with ordinary feed and 0.854 kg was from the fish species fed with the formulated feed. The mean PH, temperature, DO and turbidity during the experimental period were 8.2 moles/L, 22.02 0C, 5.44 mg/L cm & 12.577cm respectively. All the water quality parameters were within the optimum range of fish production except the mean temperature which was found below the optimum value and thus may be one of the reasons for the slow growth of fish in cage. Thus under the optimum condition of fish production, cage fish culture supplied with formulated feed has proven better result than the ordinary feed on farm condition of freshwater pond at IAAS.
