ABSTRACT

Altivelis Cromileptes grouper is one type of sea fish with high economic value and has a very good prospect for propagation. Humpback grouper cultivation today has grown and as well as fish farming in general, one of the determining factors of success is determined by feed management. On feed management, one important aspect is the dose of feed given to farmed fish. In this study, feed samples used is made in the form of pelleted feed with flour shells mabe different doses (0%, 10%, 20% and 30%). Results showed the treatment effect on the growth of absolute weight, specific growth rate and feed conversion ratio. The best treatment was obtained in treatment D (30% flour shells mabe) which resulted in the growth rate the absolute weight of 7.83 ± 1.09 grams, the specific growth rate of 3.66 ± 0.25 % per day and 7.27 ± 0.28 feed conversion.
