Abstract
Tiger grouper fish commonly known as groupers and it is the one commodity that has domestic and international market opportunities. Purpose of this study is to determine the effect of different feeding pellets and squid on the growth and survival of tiger grouper (Epinephelus fuscoguttatus). The study was carried out on April 25th, 2014 until May 24th, 2014 in Hatchery home scale, Saga vilage, District of Tanjungpandan, Belitung province. The experimental design in this study is using a complete randomized design (CRD) with 2 treatments and 4 replicates, they are treatment A (pellets) and treatment B (squid). Result shows the highest average weight gain of biomass tiger grouper seed obtained on treatment A (pellets) biomass weight gain is 16.18 grams and survival 100%, whereas treatment B (squid) the biomass weight gain 11.53 grams and survival 85%. The results of t test step, note that the value of T count is greater than the T table which means the ratio of feed pellets and squid provide highly significant influence on the growth and survival of seed tiger grouper (Epinephelus fuscoguttatus). Water quality maintenance media for research is still at a decent range of temperature is from 27.5-30°C, pH 7.6 - 8, and dissolved oxygen 3.4-5.4 ppm. Key Words: tiger grouper, growth, survival rate, feed
