Peningkatan Vitalitas dan Kelangsungan Hidup Benih Kerapu Lumpur, Epinephelus coioides Melalui Pakan yang Diperkaya dengan Vitamin C dan Kalsium
Abstract: Further development
of grouper culture facing the problems of unsucessful seed production, mostly
due to high rate of larval deformity and mortality. Fortification of artificial
feed with vitamin C and calcium is intended to increase vitality and improve vertebrae
growth of orange spotted grouper, Epinephelus coioides seed. The experiment was
conducted in a completely randomized design consisted of 4 treatments in terms
of diets fortified with vitamin C + calcium (A), Vitamin C (B), Calcium (C),
and control (D), with 3 replicates each. The treatments were applied to 20 days
old seed which was reared up to juvenile stage (D45). The growth rate of was
checked at 5 days interval and survival rate was calculated based on mortality
data when the experiment terminated. The results showed that the highest
(p<0.05) survival rate (4.38%), growth (TL 17.37 mm, BW 75.21 mg), daily
growth rate of body weight (6.48%) and deformity (3.18%) were obtained from the
seeds fed vitamin C + calcium fortified diet.
