dc.description.abstract | This research was conducted to determine the dose of rGH giant gouramy (r- OgGH) given through immersion that generate the highest growth of gouramy juvenile. The dose of rGH used was 10 mg / l, 20 mg / l, and 30 mg / l and without administration of rGH as a control. Fifty fries of 2 days after the yolk egg absorbtion were immersed into 200 ml of rGH solution for 60 min. Immersion was performed 3 times and applied once a week. The fish were reared in aquaria at stocking densities of 7 fish/l for 5 weeks and fed on Artemia nauplii and blood worm 2 times a day ad libitum. The results showed that the average body weight of 30 mg/l (0.3394 g) and 20 mg/l (0.3179 g) rGH-treated fish were higher (P<0.05) compared to that of 10 mg/l (0.2423 g) and control (0.1939 g). There was no body weight differences (P>0.05) between the fish treated with 20 mg/l and 30 mg/l of rGH, and between the fish treated with 10 mg/l rGH and control. Furthermore, the growth rate of rGH-treated fish was higher (P<0.05) compared with control. Survival of fry treated with rGH 30 mg/l (100%) was higher than the control and other treatments. Thus, immersion of fry in 30 mg/l rGH solution can be applied to enhance the growth of giant gouramy with a high survival rate. | en |
