Abstract

The purpose of this study was to determine the effect of adding vitamin C in artificial feed and the
optimum dose to the growth of snakehead fish seeds. The research method used was a completely
randomized design with 4 treatments and 3 replications. The treatments used were: A (giving
vitamin C at a dose of 50 mg/kg of feed), B (giving vitamin C at a dose of 100 mg/kg of feed), C
(giving vitamin C at a dose of 150 mg/kg of feed), D ( giving vitamin C at a dose of 200 mg/kg of
feed). The results showed that the highest average biomass growth was obtained in treatment D
with a dose of vitamin C 200 mg/kg of feed, the increase in biomass reached 3.04 grams. While the
lowest growth was obtained in treatment A with a dose of vitamin C 50 mg/kg of feed resulting in
an average growth of 1.09 grams. The results of the analysis of variance on the growth of
snakehead fish seed biomass showed that the calculated F value was greater than F table 1% and
5%. The range of water temperature during the study was between 27 -30
o
C, water pH ranged from
7.4-7.6 and dissolved oxygen in water (DO) ranged from 4.2-4.9 mg/l.
