Abstract
Effect of different stocking densities of lionhead goldfish juveniles on growth performances, survival rate and feed cost per fish were studied. The initial average weight and total length were 2.49±0.03 gram and 4.67±0.07 centimeter, respectively. The experimental design was completed randomized design (CRD) with 3 treatments: 20, 30 and 40 fish per square meter, and 3 replications. The goldfish was stocked in a 310 liter cylindrical fiber tank for 6 weeks experimental duration. The results showed that growth performances, final weight and weight gain per day were statistically significant differences (P<0.05). Goldfish juveniles cultured at the density of 20 (average final weight of 10.40±0.01 gram) and 30 fish per square meter (average final weight of 10.33±0.06 gram), showed better growth performances than that the density of 40 fish per square meter (average final weight of 10.10±0.01 gram). The feed cost per fish did not differ between treatments, which was 0.64±0.01-0.67±0.03 Baht per fish. The survival rates of all treatments were 100 percent. Water quality parameters were suitable for the growth of goldfish juveniles as well. From the results, it could be concluded that the optimal stocking density for goldfish juvenile was 30 fish per square meter.
