  The objective of this research is to investigate the effects of rabbitfish (Siganus canaliculatus) existence in polyculture system and feed type against the growth performance of bigeye trevally (Caranx sexfasciatus) in floating net cage. Study on polyculture of bigeye trevally and rabbitfish and monoculture of bigeye trevally in the cage were conducted at the coastal of South Bolaang Mongondow, North Sulawesi, Indonesia in 2018. The experiment was designed with three treatments for bigeye trevally, namely: monoculture of bigeye trevally fed with fresh trash fish + corn oil 4% (Treatment A), polyculture of bigeye trevally and rabbitfish fed with fresh trash fish + corn oil 4% (Treatment B), polyculture of bigeye trevally and rabbitfish fed only fresh trash fish (Treatment C); On the other hand, 2 treatments for rabbitfish, namely: polycult..
