Abstract

Deep-water southern rock lobsters were translocated to inshore reefs harbouring high-market value southern rock lobsters as part of an experimental spatial management strategy to enhance their market traits, growth and post-harvest condition. We assessed the haemolymph condition of deep-water lobsters before and after (over a period of 14 months) translocation for comparison to resident lobsters at the release site using a range of moult and haemolymph indices. Moult indices indicated that deep-water lobsters were of a similar moult stage to resident lobsters before translocation, they moulted earlier than resident lobsters in their new habitat but were of a moult stage similar to resident lobsters when sampled 12 months after translocation. Comparisons of haemolymph parameters included the total haemocyte count, serum protein and electrotypes such as magnesium and potassium, which were all significantly different between deep- and shallow-water lobsters prior to translocation. These populations when sampled 12 months after translocation showed similar concentrations for all haemolymph parameters, suggesting an improved resilience to postharvest stress in translocated lobsters. Benefits of translocation to inshore areas on the post-harvest condition of deep-water lobsters could be due to improved body condition through the manipulation of habitat and diet but also from the reduced post-capture transport time and stress duration.
