Daftar Isi:
- The aim of this experiment was to find out the data and information of effect on feeding of combination of trash fish and pellet to the growth and survival rate of swimming crabs (Portunus pelagicus). The research was conducted in the research station of Research Institute for Coastal Aquaculture, Maros, South Sulawesi for 40 days. Nine aquaria were used in this research and the dimention were 60 x 40 x 40 cm. Experimental disign used the Complete Randomized Design, The treatments were applied of trash fish and artificial feed (pellet) i.e. A; 100% trash fish (Clupea sp), B; 100% artificial feed (pellet), and C; 50% trash fish + 50% pellet, with three replicates, respectively, Crablet were applied average size of 5,2 + 0,2 mm in charapace width and 0,04 + 0,02 g in body weigth. Feeding were conducted of three times a day, with dosage 15 % of total body weight a day. During the experiment, the determined parameters were body weight, charapace width, and survival rate. The result showed that artificial feed/pellet of 42% protein contain could be used as feed in swimming crabs rearing and not significant different on the growth of charapace width, body weight and survival rate (P>0.05) with the other treatment.
