Abstract: This study aims to
examine the effects of phytase enzym in artificial feed on gowth, feeding usage
and survival rate of brown marbled grouper (Ephinephelus fuscoguttatus) and to
determine the optimum dose of phytase enzym in artificial feed on growth and
feeding rate of brown marbled grouper (Ephinephelus fuscoguttatus) .
Methodology used in this study was laboratory treatments with complete random
design. The study consisted of four treatments and three repetitions. Treatment
A (0 mg/kg of feed), B (500 mg/kg of feed), C (1000 mg/kg of feed), and D (1500
mg/kg of feed). Examined parameters were absolute weight growth, specific
growth rate, feeding usage (feed and protein conversion ratio efficiency),
survival rate and water quality. Varian analysis was used to analyze the data
and Double Duncan Area Test was used to test the treatment differences. The
results show that the treatments significantly (P<0.05) affected on the
grwoth and feeding usage; however, they did not significantly (P>0.05)
affect on the survival rate of brown marbled grouper (Ephinephelus
fuscoguttatus). The optimum dose of phytase enzym for feeding usage and the
growth of brown marbled grouper was 500-1000 mg/kg of feed. The water quality
was still in the viable range for brown marbled grouper cultivation.
