The effect of different live feeds on the growth and survival of comet goldfish Carrasius auratus auratu larvae

Abstract

The purpose of this study was to investigate the effect of different live feeds on growth and survival rate of comet goldfish larvae (Carassius auratus auratus) and to find the best live feeds for the growth of comet goldfish larvae (C. auratus). This research was conducted at Marine Biology Laboratory, Faculty of Marine and Fisheries of Syiah Kuala University, Banda Aceh. The study was conducted on July 27 to August 24, 2017. This study used Completely Randomized Design (CRD) using 4 treatment levels with 4 replications that were A (Tubifex sp.); B (Moina sp.); C (Daphnia sp.); and D (Artemia sp.). The ANOVA test results described that different live feeds effected survival rate, absolute weight gain, absolute length gain, specific growth rate and daily growth rate of comet fish larvae (Carrasius auratus auratus) where P<0.05. The results of this study showed that treatment A (Tubifex sp.) was the best treatment which resulted in average of survival rate was 97.50 ± 5.00 %, absolute length gain was 2.45 ± 0.30 cm, absolute weight gain was 0.39 ± 0.13 g, specific growth rate was 0.12 ± 0.02 %/day, and daily growth rate was 0.014 ± 0.0003 g/day.
