| Abstract: | ABSTRACT The presence of the “symbiotic” red alga Hypneocolax stellaris Borgesen was found to substantially reduce the growth rate of Hypnea musciformis (Wulfen) Lamouroux. The growth rate of injected field material was 40% less than unifected thalli. Likewise, the growth rate of host thalli infected in the laboratory was reduced 70% compared to uninfected thalli. Neither the quantity nor quality of carrageenan extracted from Hypnea musciformis was directly affected by the presence of Hypneocolax stellaris. In a mariculture system the presence of a symbiotic alga on its host would be expected to reduce the host's growth rate and thereby lower its economic potential. |
