Abstract

The supply of fish that rely on catches in nature cannot meet the needs market continuously, so research is needed to accelerate spawning through additional glutathione and vitamin E in commercial feed to produce quality fish fry. This research aims to determine the effect of the addition of vitamin E in the commercial feed containing glutathione to increase the spawning of kissing gourami, among others, hatching rate, the egg diameter, and the survival rate. The maintenance of kissing gourami had done for two months. The research used a Completely Randomized Design (CRD) with 4 treatments and 3 replications. Treatment A (Glutathione), B (Glutathione and Vitamin E 150 mg.kg-1), C (Glutathione and Vitamin E 300 mg.kg-1), and D (Glutathione and Vitamin E 450 mg.kg-1). Feeding three times a day morning, noon, and evening with 5% of the weight of the fish body. The result showed that all parameters were significant. The highest hatching rate was 99,67% in treatment D. Egg diameter in the treatment of C gave the best result was 0,88 mm. The highest fecundity was 21.257 grains in treatment D. The highest survival rate was 95,56% in treatment D. The addition of glutathione and vitamin E on commercial feed could improve the spawning kissing gourami fish and the optimum dosage of vitamin E is 282 mg.kg-1. The range of water quality^s value during the research was within normal range.
