Abstract

The community service activity reported in this paper was conducted in Malumbi Village, East Sumba Regency, East Nusa Tenggara. The target of this community service was the Tani Tunas Baru group and the Malumbi Farmer group. The purpose of this service was to provide knowledge and information to these two farmer groups about good and correct fish farming techniques and the application of EM-4 probiotics as feed for catfish. The activity consisted of two, namely workshop and mentoring. The service provided new knowledge and insight to the two farmer groups. The farmers were shown activities such as preparation for maintenance ponds, fertilization techniques, seed spreading techniques in new containers, good and correct feeding techniques, and water replacement systems car. In addition, assistance related to probiotic applications was also implemented. The results showed that the administration of probiotics EM-4 gave good results on the growth rate and survival of the catfish each by 18% and 80% when compared to controls. It is hoped that fish farmers in the Tunas Baru and Malumbi groups are able to apply the knowledge that they have learned.

Abstract

The aim of this study was to examine the effect of vitamin E on gonad maturation and determining the best doses in improving of gonad maturation in nilem fish. In this study used a flock of fish brood which is never experienced spawning. There are 4 doses of vitamin E which used in this research following by 0, 125, 250, and 375 mg kg-1. The results showed that fortified of vitamin E which were in feed significantly affected to the percentage of gonad development, gonado somatic index (IGS), hepato somatic index (IHS), fecundity, diameter of eggs, and the percentage of egg maturity at P<0.05. The result showed that the best dose of vitamin E to reach gonad maturity were 375 mg kg-1 with six weeks maintenanced. The percentage of gonad maturity was 100%, IGS was 11.50%, IHS was 0.34%, fecundity was 23.484 eggs/individual, the diameter of the eggs were 0.31 mm, and the percentage of mature eggs 64.44%. These results supported the potentially of feed additives such as vitamin E plays a critical role in enhancing gonad maturation in Nilem fish thereby providing a methods to improve fish reproduction.
