This record describes the datasets obtained on Courageous Cruise 051. The data were obtained from the Joseph Bonaparte Gulf in June and July 1979. Trawls for demersal fish were made and the species studied included long nosed tripple spine (Trixiphicththyus weber), Blue spot trevally (Caranx bucculentus), Brush-tooth Lizard (Saurida undosquamis), Lesser spangled emperor (Lethrinus choerorhynchus), Saddletailed sea perch (Lutjanus malabaricus), Red big eye (Priacanthus macrocanthus) and Painted sweetlip (Plectorhynchus pictus). Length, sex, numbers and age were determined. Two hydrological transects plus XBT observations were also carried out.(derived from the cruise report) - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.

This record describes the datasets obtained on Courageous Cruise 049. The data were obtained from the Australian North West Shelf in April and May 1979. Trawls for demersal fish were made and the species caught included Lesser spangled emperor (Lethrinus choerorhynchus), Saddletailed sea perch (Lutjanus malabaricus), Red big eye (Priacanthus macrocanthus) and Painted sweetlip (Pomadasys pictus), together with increased abundance (compared with 1978) of spangled emperor (Lethrinus nebulosus), yellow streaked sea perch (Lutjanus vitta), red spot emperor (Lethrinus lutjan) and blunt-toothed snapper (Pristipomoides microlepis). Detailed biological collections (otoliths, scales, stomachs and gonads) were made of six species, Nemipterus peronii, Saurida undosquamis, Lethrinus choerorhynchus, Lutjanus malabaricus, Priacanthus macracanthus, and Plectorhynchus pictus. Additional observations were made on sex-specific length frequency, gonad condition, stomach fullness, and stomach contents.(derived from the cruise report) - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.

This record describes the datasets obtained on Courageous Cruise 052. The data were obtained from the Australian North West Shelf in July 1979. Trawls for demersal fish were made over two 48 hour periods and the species studied included Perons threadfin bream (Nemipterus peronii), Brush-tooth Lizard (Saurida undosquamis), Lesser spangled emperor (Lethrinus choerorhynchus), Saddletailed sea perch (Lutjanus malabaricus), Red big eye (Priacanthus macrocanthus) and Painted sweetlip (Plectorhynchus pictus). Length, sex, numbers and age were determined. Temperature observations from an XBT were also obtained.(derived from the cruise report) - Biological Field Data Sheets recorded during this voyage have been scanned to PDF, and are available (to CSIRO Staff) on-line.
