This record describes the datasets obtained on Courageous Cruise 050. The data were obtained from the Australian North West shelf in May and June 1979. Trawls for demersal fish were made and the species caught included Lutjanus and Nemipterus spp. and the brush tooth lizard fish (Saurida undosquamis). Other species found further to the north included Saurida micropectoralis, Gassa miuta and leiognathus fasciatus. Pelagic fish caught included Pellona ditchella, northern bluefin tuna (Thunnus tonggol), mackerel tuna (Euthynnus affinis), and skipjack tuna (Katsuwonus pelamis).(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.

7, four- to five-day cruises were undertaken using the vessel "Jacqueline D" in Albatross Bay, Gulf of Carpentaria between August 1986 and November 1988, using a random stratified trawl survey to measure fish species composition and abundance. Four depth zones between 7 and 45 m were sampled during both day and night. Approx. 890,000 fish of 237 species were collected, of which the bulk were made up of 25 species. The dominant families were Leignathidae, Haemulidae and Clupeidae, with Sciaenidae and Dasyatidae important at night. Leiognathus bindus was the most abundant species, while Caranx bucculentus was the most frequently caught (96% of all trawls). The suite of fishes was separately analysed for occurrence of prawn predators.

This record is an overview entry for biological data collected on Soela cruise SO 5/80. This cruise took place in the North West Shelf, the West Australian north coast and the Timor Sea during 21 June - 26 July 1980, under the leadership of W. Okera. Biological data collected on this cruise include EK 50 and Simrad 1100 acoustic data and observation data from the Atlas Fischfinder. Samples and biological data of 23 species of Carangidae, 4 species of Scombridae, at least 8 species of Leiognathidae, 6 species of clupeoids, 3 species of Sphyraenidae, 1 species of Trichiuridae, 1 species of Parastromateidae and 6-7 species of sharks. Plankton samples for abundance estimates. Bottom sediment samples from 60 dredge tows for particle size analysis, for determination of organic content and small sediment samples stained with Rose Bengol for foraminiferan studies. Photographs of 356 specimens representing about 290 species of both demersal and pelagic fish these were also retained for further examination.(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.
