Abstract:
Climbing perch are freshwater fish which based on their eating habits in their natural habitat are omnivorous and are widely cultivated in South Kalimantan. The aim of this research was to determine the effect of different fasting times on the growth rate, survival and efficiency of feed utilization in Climbing perch fry. This research used a completely randomized design with 4 treatments and 3 replications. Treatment A: 1 day of fasting and 1 day of feeding;
treatment B: 2 days of fasting and 1 day of feeding; treatment C: 3 days of fasting and 1 day of feeding; and treatment K: fed every day (control). Parameters observed included growth in length and relative weight, survival, feed utilization efficiency and FCR. The results of this study showed that food starvation had a significant effect on relative length growth (5.06 ± 3.90-39.14 ± 4.89), relative weight growth (15.94 ± 8.04-176.44 ± 26), feed utilization efficiency (6.72 ± 3.47-52.22 ± 6.54) and had no significant effect on FCR (1.94 ± 0.26-11.42± 5.85). The highest average survival results were in treatments A and K at 100% and the lowest were in treatment C at 88%.
