Feeding rate of brown algae Siganus fuscescens reared on rabbitfish Eisenia bicyclis for 17 days at 26 and 29℃ were 32.20% of body weight( BW) /day and 39.05% BW/day. Specific growth rate( SGR) at 26 and 29℃ was 51% and 70% of fish fed commercial dry pellet 2.5% BW/day, respectively. It is considered that S. fuscescens has the ability to utilize nutrients of E. bicyclis, although a large amount of alga would be required to enable growth due to its poor nutritional value.
