抄録: Kappaphycus alvarezii (Doty) Doty ex. Silva, red seaweed, was cultured in deep seawater and in different concentration of NO_3-N at the laboratory. Higher daily growth rate (DGR) of the thallii were observed as 1.17% in deep seawater. The materials in 1mM NO_3-N, lower concentration nitrogen enrichment to normal surface seawater produced daily growth rate (DGR) of 0.97%, while a higher NO3 content suppressed the growth of the thallus and showed DGR of 0.51%. The growth of new branches, wound healing and regeneration capacity of the thallus is much faster in the deep seawater medium with a DGR of 0.94%, which is nearly double than the normal seawater (DGR: 0.48%). The results suggest that deep seawater can be effectively used as a cheap medium for culture and mass cultivation of Kappaphycus as well as many other marine algal species and low NO_3 enrichment can enhance the growth rate.
