BROODSTOCK GONADS MATURATION LEVEL OF CLIMBING PERCH (ANABAS TESTUDINEUS BLOCH) WITH ZINC SUPPLEMENTATION IN FEED

Abstract

Climbing perch is one of the fish species that is in great demand by the public because of its distinctive taste, tasty and slightly fatty meat. A very important factor in ensuring the continuity of seed availability for cultivation activities depends on the readiness of the gonad-ripe parents, one of which is the female parent. Gonadal maturation can be increased by providing optimal feed for broodstock containing essential nutrients (protein, fat and vitamins). This study aims to analyze the effectiveness of adding zinc to the feed given and to analyze the optimal dose of zinc addition to the feed on the performance of the reproductive organs of female climbing perch. This study used a completely randomized design with 4 treatments and 3 replications. Treatment A commercial feed (CF)+0 mg zinc; B CF+100 mg Zinc; C CF+200 mg Zinc and D CF+Zinc 300 mg. The results of research on feeding zinc can improve the reproductive performance of climbing perch with a range of average levels of maturity and gonadal histology III-IV gonads.
