EFFECTS OF DIFFERENT FEEDING FREQUENCIES ON THE GROWTH OF KOI CARP (CYPRINUS CARPIO) FRY
Abstract
This study was conducted to investigate the effects of feeding frequencies on the growth of koi carp. Juvenile (weight: 0.015 ±0.001 g) koi carp (Cyprinus carpio) were fed two, three, and five times per day with a ration comprising “granule fish feed” equivalent to 18% of their body weight during the entire experimental period of 60 days.
At the end of the experiment, the mean weight and the mean weight gain were 0.474 ±0.060, 0.494 ±0.090, 0.579 ±0.050 g; 0.459 ±0.055, 0.479±0.089, 0.564 ±0.046 g for the fish fed two, three, and five times per day, respectively. Feed conversion ratio, specific growth rate, protein efficiency ratio, and survival rate were found to be 2.43 ±0.070, 2.89 ±0.340, 2.55 ±0.070, 5.73 ±0.190, 5.77 ±0.300, 6.04 ±0.090, 0.89 ±0.02, 0.75 ±0.09; 0.81 ±0.02; 70 ±11.5, 70 ±5.77, and 66.66 ±3.33; respectively. No significant differences were observed among the fish groups fed with different frequencies in terms of weight gain, feed conversion ratio, specific growth rate, protein efficiency ratio, and survival rate (p>0.05).
