Long-distance movements in Jasus spp. And their role in larval recruitment

Large-scale, directed migration of juveniles or adults can be important to the larval recruitment process in rock lobsters. patterns of long-distance movement of Jasus spp., particularly J. edwardsii and J. verreauxi in New Zealand and Australia, are reviewed. Long-distance (at least 5 km) alongshore migrations by late juveniles appear to take place against the net coastal flow in parts of both New Zealand and Australia, some of these migrations appearing to be contranatant and crucial to larval recruitment. Long-distance alongshore migrations have not been shown for other species but their possible existence cannot be ruled out. In most or all Jasus spp., there an also inshore-offshore migrations, associated with molting and reproduction, which can exceed 5 km, and long-distance movements without common direction.
