Population dynamics of Scyllarid lobsters of the genus Thenus spp. on the Queensland (Australia) east coast

摘要: The effect of different combinations tagging and release methods was examined on the survival, moulting, growth increment recapture rates slipper lobsters Thenus spp. Queensland (Australia) east coast using generalised linear modelling methods. Laboratory experiments indicated that while is unlikely to significantly affect survival rate or increments lobsters, it likely lower incidence moulting. In field, tagged increased markedly by applying an antibiotic/antifungal ointment tag wound minimising length time were held board prior release. Recapture for orientalis declined about 0.5% every hour release, even though they kept in aerated seawater. About twice as many male T. recaptured compared females. Reasons this may be related size differences between sexes how fishers valued rewards classes. T-bar anchor affected indicus; with small tags 33% higher than those large tags. Two also compared; surface bottom cage several hours improved method. However, under some conditions, relative method, possibly because stress trauma from crowding cage. For both species, period at liberty increasing lobster size. Females had larger males.
