The experimental fish body weight was 55.9 g average. The treatments employed in this experiment include repeating cycles of one day starvation followed by two and three days refeeding alternately (T1); repeating cycles of one day and two days starvation alternately followed by two days re-feeding (T2); repeating cycles of one week starvation followed by one week feeding (T3); and feeding daily as control (C). Each treatment was assigned to five net cages according to completely randomized design. Twenty-five individuals were stocked in each cage. The fish were fed with trash fish at noon at 5% of bodyweight. Water quality parameters including pH, temperature and salinity were monitored daily, while dissolved oxygen was measured weekly. The results show that the final body weight of fish in T1 was not significantly different from that in control (P>0.05). However, the final body weight of fish in T2 and T3 was significantly lower than control (P<0.05). Short term cycled starvation and refeeding affects compensatory growth and body condition indices of orange spotted grouper. These findings suggest that repeating cycles of one day starvation followed by two and three days refeeding alternately could be applied for rearing orange spotted grouper. Such a feeding schedule scheme provides economic and ecological benefits through a reduction in operational costs and waste from fish. Keywords : Starvation Compensatory growth Epinephelus coioides
