Daftar Isi:
- The aim of this experiment was to find out data and information of growth rate, survival rate and yield of swimming crabs (Portunus pelagicus) and rabbit fish (Siganus gutatus) which cultured together with different stocking density of rabbit fish in brackishwater ponds. Nine brackishwater ponds with the dimention of 100 m2 with 100 cm depth were used. Crablet of 17th of 7.2 + 0.2 mm charapace width and 0.05 + 0.02 g body weight were used in this research with stocking density of 300 ind/100 m2. During the rearing the crabs were fed trash fish (Sardinella sp) given of twice a days, dosage 5% of total body weight. Experiment was carried out on complete randomized design with treatments were stocking density of rabbit fish i.e. 20 ind/100m2 (A), 30 ind/100 m2 (B), and 40 ind/100m2 (C) with three replicates. The rabbit fish of length were 9.1 + 0,8 cm and weight of 15+ 0.6 g were used. The result showed that the growth of body length and weight and survival rate of swimming crabs and rabbit fish were not significantly different (P>0.05), but the yield of rabbit fish was significantly different (P<0.05).
