ABSTRACT Three closed systems were evaluated for the transport of abalone larvae for use in remote settlement associated with mass culture activities. The first of these systems maintained the larvae in seawater, the second in seawater with oxygen added, and the third in wet condition without seawater but with oxygen added. Survival of the larvae was determined within each system over periods of 10, 16, and 36 h. In a separate experiment, larval settlement in aquaria was determined after holding the larvae in the three different transport systems for l0 h. The results showed the best survival was obtained for the larvae in water alone, with survival rates ranging from 97% ...
