Growth of Sunu Grouper (Plectropomus leopardus) Larvae That Given Rotivera (Bachionus rotundiformus) Enriched with Taurine and Glutamine

摘要

This study aims to determine the effect of taurine and glutamine enriched Brachionus on the growth and survival rate of Sunu Grouper (Plectropomus leopardus). This research was conducted in Marine Research and Fisheries Extension Center Gondol, Bali. The study was conducted for 1 month on September 2017. The research method used was using Completely Randomized Design (CRD) consisting of 4 treatments and 4 replication, namely treatment A (without Taurine and Glutamine; (B) 0,5 gram Taurine / 10 L media; (C) 0,5 gram Glutamine / 10 L media; (D) 0,5 gram Taurine and 0,5 Glutamine / 10 L media. The age of Sunu Grouper was D-2 until D-10, parameters observed were Survival Rate, Average Daily Length, Relative Growth Rate, number of Brachionus in the digestive tract, and water quality. Which included DO, temperature and pH. Data were analyzed using analysis of variance with F test with 95% confidence level and the difference between treatments was tested by Duncan multiple-range test, then water quality was analyzed descriptively by comparing to related literature and water quality standard according to SNI 1999. The results showed that the use of 0,5 gram Taurine and 0,5 gram Glutamine enriched Brachionus, had an effect on the growth of Sunu Kerapu.
