EFFECTS OF VITAMIN C IN HIGH-ENERGY FEEDS ON GROWTH AND SURVIVAL RATE OF TIGER GROUPER SEEDS (EPINEPHELUS FUSCOGUTTATUS)
ABSTRACT: This research was
aimed to study the effect of vitamin C on diets with low protein and high
energy content on growth and survival rate of tiger grouper (Epinephelus
fuscoguttatus) juveniles. It is also to know the dose or the best level
concentration of vitamin C on growth and survival rate of tiger grouper (E.
fuscoguttatus) juveniles. Tiger Grouper juveniles of 0,77+0,07 g initial body
weight were reared in aquarium 60 cm x 40 cm x 40 cm with 7 ind. / 35 L.
Artificial feed were fed in at satiation. The juveniles were fed dry pellet
diets which containing 40% protein and 20% lipid in different levels of vitamin
C (Ascorbate-2-Sulfate):0 mg/kg, 75 mg/kg, 150 mg/kg, 225 mg/kg. The
experimental laboratoris method was conducted using Completely Randomized
Design with three replicate for each treatment. The result of the experiment
showed that there was a very significant effect of treatments on the SGR
(Spesific Growth Rate), FCR (Feed Conversion Ratio), PER (Protein Efficiency Ratio),
SR (Survival Rate) of tiger grouper (E. fuscoguttatus) juveniles (P < 0,01).
That values more higher after added vitamin C (Ascorbate-2-Sulfate). Best
treatment was obtained at supplementation vitamin C of 150 mg/kg. On the other
hand be lower at highest dose on treatment D (225 mg/kg). Its indicated that
vitamin C can improve and give better on growth and survival rate. The optimum
condition of water quality also have been led to significant improvement in
growth and survival rate
