Abstract

The purpose of this study was to determine the addition of probiotics in commercial feed to the growth and survival of Asang fish (Osteochilus vittatus CV) fry. This study used an experimental method with a completely randomized design (CRD) with 4 treatments and 3 replications. The test fish used were 120 fish with a size ranging from 5-8 cm. The test fish were kept in a waring cage made of a type of paralon frame with a size of 40 x 40 x 45 cm. The treatment in this study was A (without probiotics), treatment B (addition of probiotic 10 ml/kg of feed), treatment C (addition of probiotic 20 ml/kg of feed), and treatment D (addition of probiotics 30 ml/kg of feed). From the results of this study, the highest specific growth rate was found in treatment D (6.66 ± 1.15 g), while the mean survival was 100% for all treatments. The highest FCR of fish fry was found in treatment A namely 1.43 ± 0.22, and the lowest in treatment D namely 1.12 ± 0.21, and for feed efficiency in treatment D, namely 95.24 ± 1.04 %.Keywords:Asang fishEfficiencyGrowthSurvival

Highlights

Asang fish is a freshwater fish that are often discovered in rivers, lakes, or reservoirs, which have a strategic value, as a source of food and income for the rural community and can be cultivated. (Azrita et al, 2014)
The analysis of variance showed that the addition of probiotics to commercial feed had no significant effect (P> 0.05) on absolute weight gain, specific growth rate, survival rate and Feed conversion ratio (FCR), but significantly different on absolute length growth and feed efficiency for asang fish seeds
The high survival rate of Asang fish seeds was taken into account because of the appropriate density and quality of the feed and because of the texture and smell of the feed with probiotics

Summary

Introduction

Asang fish is a freshwater fish that are often discovered in rivers, lakes, or reservoirs, which have a strategic value, as a source of food and income for the rural community and can be cultivated. (Azrita et al, 2014). Asang fish is a freshwater fish that are often discovered in rivers, lakes, or reservoirs, which have a strategic value, as a source of food and income for the rural community and can be cultivated. The species has significant economic value because it is relatively cheap in price and the citizen often like it. In West Sumatra, the selling price ranges from IDR 25,000 per kg (Azrita et al, 2014). The seeds of this species are obtained from wild catches in nature, and the domestication of these fish is needed to avoid extinction. If this fish is successfully domesticated, it is likely to be used as a candidate for cultivation. The research by Helwidda (2019) showed that the hatching of Asang fish eggs could reach 71.11% with larval survival of 91.55%
