Pengaruh Perendaman Telur Dengan Dosis Vitamin C Berbeda Terhadap Daya Tetas Telur, Pertumbuhan Dan Kelulushidupan Larva Ikan Gurami (Osphronemus Gouramy Lac.)
This study was conducted on February-March 2020 at the Fish Hatchery
and Breeding Laboratory, Faculty of Fisheries and Marine, University of Riau,
Pekanbaru. The purpose of this study was to determine the effect of immersion
eggs with different doses of vitamin C on hatchability, growth, and survival of
gouramy larvae. This study used a Completely Randomized Design (CRD) with 5
treatments and 3 replications. Different doses used on this study were; C0 (0 mg /
L), C50 (50 mg / L), C100 (100 mg / L), C150 (150 mg / L) and C200 (200 mg /
L). Immersion of gouramy egss with vitamin C for 3 hours with density 150 eggs
and water volume 5 L. Gouramy larvae were maintained for 20 days.The results
showed that different dose of vitamin C solution had a significant effect (P 0.05)
on absolute length growth, absolute weight growth, specific growth rate and
abnormalities of gouramy larvae. The best dose of vitamin C to increase the
fertilization rate, hatching rate and survival rate of gouramy larvae was 200 mg/L.
The quality of water during the study were temperature 26.3-28.2 ºC, pH of
immersion water 5.5-5.8, pH of hatching water 5.9-6.3, pH of larvae maintenance
water 5.7-6.5 and DO 6.0-6.6 mg/L.
