ABSTRACT
This research was conducted on October - November 2020, at Fish Hatchery and
Breeding Laboratory of Fishery and Marine Science Faculty of Riau University.
The aim of this research was to determine the effect of Recombinant Growth
Hormone (rGH) and the optimal dose and immersion duration on growth and
survival rate of tambaqui larvae (Colossoma macropomum). The method used
was a Completely Randomized Design Factorial with 2 factors. The first factor
was the dose of rGH with 3 levels; 0 mg/L (D0), 1.5 mg/L (D1,5) and 2.5 mg/L
(D2,5). The second factor was the immersion duration with three levels of 30
minutes (W30), 60 minutes (W60) and 90 minutes (W90) respectively. The larvae
were cultured preserved in aquarium for 40 days with 2 fish/L density. The results
showed that the use of different doses and immersion duration of rGH effected
on absolute weight, absolute length, specific growth and survival rate of river
catfish larvae. Treatment dose 1.5 mg /L and 60 minutes (D1,5W60) with the
result of absolute weight growth of 2.88 grams, absolute length 4.87 cm, specific
growth rate of 18.45 % and survival rate of 91.10 %. The water quality parameters
during the study were optimal for river catfish larvae with temperature 26.7-27.9
oC, pH 5.9-6.9 and dissolved oxygen 6.3-7.3 mg/L.
Keywords: Doses, Immersion Duration, Recombinant Growth Hormone,
Colossoma macropomum, Growth, Survival Rate.
