ABSTRACT
This research was conducted on September 12, 2020 - October 12, 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 thyroxine
hormone and the optimal dose and immersion phase on growth and survival rate
of river catfish larvae (Hemibagrus nemurus). The method used was a
Completely Randomized Design Factorial with 2 factors. The first factor was the
dose of thyroxine hormone with 4 levels; 0 mg/L (D0), 0,1 mg/L (D1), 0,3 mg/L
(D2), and 0,5 mg/L (D3). The second factor was the immersion phase with 2
levels of immersion egg (FL) and immersion larvae (FL). The larvae were
cultured preserved in jars for 30 days with 2 fish/L density. The results showed
that the use of different doses and immersion phase of thyroxine hormone
effected on absolute weight, absolute length, specific growth and survival rate of
river catfish larvae. Treatment dose 0,3 mg /L and immersion larvae (D2FL) with
the result of absolute weight growth of 2.08 grams, absolute length 5.02 cm,
specific growth rate of 20.94 % and survival rate of 92.00 %. The water quality
parameters during the study were optimal for river catfish larvae with temperature
27.8-28.9 oC, pH 5.9-6.9 and dissolved oxygen 3.5-6.8 mg/L.
Keywords : Doses, Immersion phase, Thyroxine hormone, Hemibagrus nemurus.
