抄録: Specimens of Gracilaria edulis, G. salicornia, Gracilaria Sp. A and Gracilaria Sp. B were collected from Manado, Indonesia, transported and cultured in Usa Marine Biological Institute, Kochi University, Japan. Daily growth rates (DGR) of these materials were measured under different levels of temperature, salinity and irradiance in laboratory controlled conditions using a temperature-controlled closed circulating system ("aquatron") and outdoor tank cultivation system. The maximum DGR were found on Gracilaria edulis, G. salicornia 5.1%±0.9, 4.9±0.8 Gracilaria Sp. A. 3.25±0.9 and Gracilaria Sp. B. 4.9%±1.1 under optimum condition. All species grew well within a temperature range of 25-30℃, salinity range of 25-35‰ and irradiance from 100-200μmol photon m^<-2> s^<-1>. In outdoor tank cultivation. The highest DGR of each species was found at a temperature range of 25-30℃, salinity of 30-35‰ and an irradiance of 150-300μmol photon m^<-2> s^<-1>. The gel strength of each species was G. edulis 580 g cm^<-2> and Gracilaria Sp. B, 540 g cm^<-2> was higher than both Gracilaria Sp A, 520g cm^<-2> and G. salicornia, 80g cm^<-2>. The agar yield obtained were Gracilaria Sp. A, 26.2%, G. edulis, 28.3 %, Gracilaria Sp. B, 27% and G. salicornia, 8.6%.
