The study of the effect of feeding with the addition of activated charcoal on feed conversion ratio and survival of juvenile Giant Trevally (Caranxignobilis) was carried out in May to August 2018. This study consisted of 5 treatments and 4 replications. Feed is treated with the addition of activated charcoal of different types, namely coconut shell activated charcoal, mangrove wood activated charcoal, rice husk activated charcoal, and palm shell activated charcoal. Addition of activated charcoal in feed at each treatment as much as 2%. Feed was given twice a day in at-satiation for 42 days. The results showed that feeding with the addition of activated rice charcoal had a very good effect on feed conversion. There was no significant difference between the treatments of activated charcoal on the survival of the juvenile Giant Trevally. The survival rate was around 88.33% 96.67%.
