Note
Since 1975, G. tikvahiae has been cultivated at the Harbor Branch Institution in Fort Pierce, Florida, as part of a continuing program on seaweed mariculture. One focus of the research in this experimental system has been on manipulating environmental factors that can readily be controlled on a larger, commercial scale (e .g., nutrient enrichments and flow rates of seawater, but not light, temperature, and salinity) . This communication will briefly review some of the findings of this research, with an emphasis on how the biology of G. tikvahiae interacts with the environmental conditions of the cultivation system.
