Green and brown strains of Eucheuma denticulatum and new cultivated strain Kappaphycus striatum were collected from commercial cultivation ground in Philippines. Daily growth rates (DGR) of the materials were measured under different temperatures and photon fluence in laboratory controlled conditions and at different depths in the sea using the floating raft culture method in Uranochi Inlet, Tosa Bay, Southern Japan. The highest DGR of E. denticulatum (brown strain) (2.76% ±0.64) and K. striatum (green strain) (4.5% ±1.51) were recorded at 25°C. K. striatum (both strains) had the highest DGR and grew over a wide range of temperatures. Observation on the effect of photon fluence showed that K. striatum (brown strain) grew well (DGR = 5.16%±1.3) at 145 µmol photon m-2 s-1.In the floating raft cultivation, K. striatum (green strain) had a DGR of3.1% ± 0.93 higher than E. denticulatum (brown strain)(2.73% ± 0.43).
