The objective of this research was to analyze the effectiveness of additional vitamin c to live feed artemia, at different doses on the growth and survival of lemeduk fish (barbonymus schwanenfeldii). this research used completely randomized design method consisting 5 treatments and 3 replications. the treatments tested were the addition of vitamin c in live feed of artemia, namely a (artemia without vitamin c enrichment), b (artemia enriched with vitamin c 100 mg/l), c (artemia enriched with vitamin c 200 mg/l), d (artemia enriched with vitamin c 300 mg/l) and e (artemia enriched with vitamin c 400 mg/l). anova test results showed that the addition of vitamin c in the artemia feed had a significant effect (p0.05) on the absolute weight and length variability coefficient. the research showed that the highest value of absolute length growth and daily growth rate were found in treatment d (artemia enriched with vitamin c 300 mg/l) with an absolute length growth of 6,6±0,48 mm and daily
