Transporting first to third instar swimming crabs, Portunus trituberculatus, on drift seaweeds was effective at preventing loss of pereiopods. When crabs were transported without drift seaweeds, pereiopods, walking legs, and swimming legs in particular decreased remarkably with instar development. Crabs transported on drift seaweeds (500-1000 g per 20 l of seawater) retained significantly more pereiopods than controls. Since it is not necessary to collect drift seaweeds at the time of release, this method can also be applied to the release of swimming crabs.
