Domestication of manggabai fish (Glossogobius giuris) through adaptation to different types of feed and aquaculture containers

Abstract

This study aims to determine the growth and survival of Manggabai fish (Glossogobius giuris) cultivated in different types of feed and maintenance containers. The method used in the study was an experimental method using a 2 × 3 Factorial Complete Randomized Design (CRD), namely two levels of rearing container factors and three levels of feed type factors. The container consists of two types of containers, namely aquarium and concrete tub. The feed given consists of three types, namely Daphnia sp., Tubifex sp. And pellets. The research variables consisted of growth and survival of test animals. The test animals used were Manggabai fish with a total length of (3 ± 0.05) cm and body weight of 4 ± 0.05 g. Data analysis in this study used a two-factor Completely Randomized Design with a probability level of P < 0.05 and used descriptive analysis of length, weight, and survival growth data during the maintenance of test animals. The results showed that the use of different feed and maintenance containers had a significant effect on the growth and survival of manggabai fish. Total absolute weight growth of manggabai fish reared in concrete containers and fed with Daphnia sp. 22.19 g, pellets 22.99 g, and those fed with Tubifex sp. Feed amounted to 39.63 g. The highest growth and survival were obtained in the treatment using a concrete tank and Tubifex sp. Feed. The highest growth and survival were obtained in the treatment using a concrete tank and Tubifex sp. Feed. The use of aquarium maintenance containers and the provision of pellets is not recommended for domestication of Manggabai fish, because it provides the lowest growth and survival.
