Difference in Fasting Time on Gonad Development of Climbing Perch (<i>Anabas testudineus</i> Bloch)

Abstract The purpose of this research was to determine the effect of fasting on the gonad development of climbing perch (Anabas testudineus Bloch) with different fasting times and feeding on gonad maturity level, gonadosomatic index (GSI), hepatosomatic index (HIS) and fecundity of climbing perch reared within 24 days. The research method used was a Completely Randomized Design (CRD) with 4 treatments and 3 replications. The types of treatment in the study were treatment A without fasting (control), Treatment B (3 days without feeding and 1 day with food), treatment C (5 days without feeding and 1 day with food) and treatment D (7 days without food and 1 day with food). Based on research results, the maintenance of climbing perch using different fasting did not significantly differ in GSI, HSI, and fecundity of climbing perch, with gonad maturity level IV and V. The gonadosomatic index (GSI) ranged between 7.79±1.12-11.37±2.02%, hepatosomatic index (HIS) ranged between 1.62±0.52-3.06±2.25% and the fecundity ranged between 8,253±1,402.06-21,334±7,201.9 eggs.
