<strong>Growth Rate of Humpback Grouper Cromileptes altivelis Cultured in Floating Net Cages.</strong> Humpback Grouper <em>Cromileptes altivelis</em> fish farming has good opportunities in the future, although still experiencing problems in its cultivation. One of the parameters that needs to be considered is the stocking density associated with the cage area. The purpose of this study was to determine the appropriate stocking density to generate optimum growth of Humpback Grouper cultivated in floating net cages. The study was conducted using the experimental method with 3 treatments and 3 replications. There were 9 cages used with the size of 1 x 1 x 1.5 m3 and a mesh size of 0.5 inches. The study was conducted in the waters of Banda Neira, Maluku, with the condition of the waters during the experiment, such as salinity which ranged from 33.2 to 34.6‰, water temperature ranged from 25 to 31°C, pH ranged from 7 to7.5, current speed 0.32–3.97cm/s, and water clarity was 14.29 to 20 m. The feed was trash fish given twice a day, in the morning and afternoon as much as 10% of total body weight of fish. After 4 months of cultivation, the absolute growth was best demonstrated by the treatment with stocking density of 25 fish/cage, which was 18.22 g, while the lowest (13.25 g) was shown by the treatment with stocking density of 75 fish/cage. The specific growth rate in the treatment of 25 fish/cage reached 1.34%/day, while the treatment of 50 fish/cage and 75 fish/cage reached 1.18%/day and 0.97%/day respectively.<br /><br /><br />

Stocking density is an important factor in cultivation, it can save land use, and increase the efficiency of fish farming. The purpose of this research was to determine the different density information on tilapia seeds measuring 2-3 cm as an alternative to using tilapia (O. niloticus) seeds 7-9 cm in size so that they can be developed in Batur Lake. The research was conducted in January - March 2020 in the floating net cages in Trunyan Kintamani village, Bangli, Bali. The research used a completely randomized design method with three treatments and three repetitions. The Tilapia seeds used are 2-3 cm with different stocking densities, 100 ind/m3, 150 ind/m3, and 200 ind/m3. The parameters observed were SGR (Specific Growth Rate), absolute growth, SR (Survival Rate), FCR (Feed Conversion Ratio), and water quality including temperature, DO, pH, TDS. The results of this study indicated that stocking density did not have a significant effect on the growth and survival rate of tilapia seeds, because the temperature was too cold so that the tilapia seeds failed to adapt properly at the beginning of stocking and the physiological conditions of the fish were disturbed so that the fish experienced stress and went to died. Water quality parameters measured include temperature with a range value of 25.86-25.880C, pH with a range value of 9.08-9.13, DO (Dissolved oxygen) with a range value of 7.9-8 mg/L, and TDS (Dissolved solids) with a range value of 1040.25-1041.58 mg/L.
