PENGARUH VITAMIN C TERHADAP PERKEMBANGAN GONAD, DAYA TETAS TELUR DAN SINTASAN LARVA IKAN LELE DUMBO (CLARIAS SP)
Abstract: The purpose of this
study was to investigate the effect of vitamin C with different doses of the
long time ripe gonads, egg hatchability and larval survival of catfish (Clarias
sp). This research used Complete Randomized Design (CRD) with four treatments
each with three replications. The treatment in this study were different doses
of vitamin C namely 0, 600, 1200 and 1800 mg / kg of feed. Data was analyzed
usung analysis of variance and continued with the Smallest Real Difference
test. Parent female catfish used was 1.5 years age with a weight of
800-900 g. Feed used was pellets
supplemented with vitamin C. Fish was
reared in four tanks measuring 2 x 1 x 1 m and fed every morning and evening ad
libitum. The results of the study was the addition of vitamin C in the diet
significantly influenced the speed of gonad maturation, egg hatchability and
larval survival. Treatment with the addition of 1200 mg / kg of feed was the
best treatment with gonadal maturation speed achieved on 39.33 days, the
highest egg hatchability 83% and survival of larvae was 7.66 days.
