Note
Outdoor growth studies were conducted in central Florida with the chlorophyte Ulva lactuca L., a productive
macroalga for which few cultivation data are available. Maximum yield of this species was found to occur
in tanks receiving a rapid seawater exchange (12 tank volumes per day) with the seaweed kept in suspension
by continuous aeration. Yields decreased, although not linearly, as either water flow or aeration times were
reduced.
