Macroalgal blooms are becoming problematic worldwide which is further exacerbated by climate change. This study looks at the effects of temperature on the growth of two pest macroalgae from Fiji, Sargassum polycystum and Gracilaria edulis, under laboratory conditions. The two algal species were subjected separately to different temperature regimes (28 , 30 , 32 and 34 Results showed a significant difference in the Specific Growth Rate (SGR) of G. edulis between the four temperatures with optimal growth at 28-30 . The SGR of S. polycystum could not be determined for experimental reasons due to biomass loss. The optimal temperature for rhizoidal length (RL) of G. edulis was 32-34 , while for S. polycystum RL was 28°C.
