Production of macroalgae, e.g., Gracilaria, in a marine culture system is enhanced by improving the manner in which the aqueous culture medium is created, namely, first adjusting the alkalinity of a quantity of freshwater by the addition of an alkaline reagent thereto, diluting seawater with such alkalinity adjusted freshwater to create a saline solution having a salinity of between about 15 to 25 parts per thousand and an alkalinity of between about 3 to 10 meq/l., dissolving carbon dioxide in the resulting solution to bring its pH to between about 7.5 and 8.5, and using such carbon dioxide enriched solution as the culture medium.
