98-104
Species of Gracilaria Greville were collected from Japan, India and Malaysia. Growth rate experiments were conducted at different temperatures, salinities and light intensities. Gracilaria vermiculophylla was found to be the fastest growing species with a growth rate of 22.32%. The growth rates of all species varied with salinities, but most of them attained their optimum growth rates at a normal seawater salinity 35‰. During the temperature tolerance experiments, it was observed that only G. vermiculophylla had a high temperature tolerance limit of up to 35°C. The temperate and the tropical species of Gracilaria were divided into three groups depending upon their optimum growth rates at the optimum temperatures. Group I consisting of G. arcuata and G. textorii from Japan with optimum growth rates at 20°C. Group II consisting of G. vermiculophylla, G. incurvata from Japan and G. foliifera, G. corticata from India with optimum growth rates at 25°C, while group III consisting of G. edulis from India and G. lichenoides from Malaysia with optimum growth rates at 30°C. |
