Growth and yield of the brown alga Ascophyllum nodosum (Le Jolis) were measured under various regimens of seawater spray culture. One‐hour periods of desiccation throughout the day and night and cessation of spray throughout the night did not affect growth relative to that in continuous spray. Desiccation for four hours during the day resulted in death. Changes in morphology from the normal intertidal growth form to that resulting from spray culture are described.
