A report on the status of the dugong in the Torres Strait area was prepared for the Australian National Parks and Wildlife Service, based on the results of an aerial survey, presenting information on dugong life history and current catch levels: Marsh H, Barker-Hudson BET, Heinsohn GE and Kinbag F. (1984) Status of the dugong in the Torres Strait area: results of an aerial survey in the perspective of information on dugong life history and current catch levels. Report to the Australian National Parks and Wildlife Service, April 1984. James Cook University of North Qld, Townsville, Australia. 72pp.

This entry describes a GBRMPA Workshop Presentation on the status of dugong in the Torres Strait. Refer to the compiled report: Marsh, H.L. And Saalfeld. K. (1991) Status of Dugong in Torres Strait. In: D. Lawrence and T. Cansfield-Smith (eds) Sustainable development for traditional inhabitants of the Torres Strait region. Proceedings of the Torres Strait Baseline Study Conference. Kewarra Beach, Cairns, QLD, 19-23 November 1990. GBRMPA Workshop Series 16 : 187-194.

In November-December 1991, dugongs, sea turtles and cetaceans were counted from the air at an overall sampling intensity of 5.8% over a total area of 30,560 square km in the Torres Strait region. The population estimates for dugongs an sea turtles were corrected for perception bias, and standardised for availability bias, with survey and species-specific correction factors. The estimates for cetaceans were corrected for perception bias only. Management recommendations are made. Refer to the report compiled for AFMA: Marsh H and Lawler I. (1992) The status of dugongs, sea turtles and dolphins in the Torres Strait region. Report to the Australian Fisheries Management Authority, June 1992. James Cook University of North Queensland, Townsville, QLD, Australia. 48pp.

The referenced report is presented in two sections. The first section reports on the results of a third survey of dugong distribution and abundance in Torres Strait conducted over four days in November 1996. The second section estimates the size of a sustainable dugong catch in Torres Strait using the Potential Biological Removal Method (PBR). The sustainability of the dugong fishery is then evaluated by comparing aerial survey estimates of the size of the dugong population in 1987, 1991 and 1996, and catch statistics from the Torres Strait Protected Zone (TSPZ) since 1991 in the context of current knowledge of dugong life history parameters.

This series of twelve, monthly, fish-spotting maps has been prepared from logs of CSIRO fish spotting aircraft, the New South Wales State fisheries aircraft and the Fish Protein Concentrate aircraft based in Tasmania. The CSIRO fish-spotting aircraft was funded by the Fisheries Development Trust Fund.

Work on this catalogue began in February 2009, and is on-going. The catalogue provides a brief description of a collection of Biological Field Data Sheets held in the O&A Bio-Data compactus No. 1 in the Hobart Marine Laboratories Block 1 Store. The compactus has six bays, and holds research vessel log sheets collected in: 1950s - Vessel Logs including biological observations + Pearl shell measurements. 1960s - Vessel Logs including biological observations + commercial Tuna and Northern Prawn. 1970s, 1980s and 1990s - Vessel Logs including biological observations. There are a few papers relating to data collected as early as 1938. Each folder of field data sheets will have a TRIM record created, then be scanned to PDF and made available via this record or the related voyage metadata record. The final aim of the project is to have a Marlin record for each data set, and as the need arises, have individual CMAR projects transcribe the data, and then add these data to the CMAR Data Warehouse.

This record is an overview entry for biological data collected on Southern Surveyor cruise SS 01/98. This cruise took place in the Great Australian Bight during February 1998, under the leadership of Jock Young. Biological data collected on this cruise include acoustic data on southern bluefin tuna (SBT) schools and their pelagic prey, collection of stomach samples from commercially-caught SBT, and photography of bottom features with an underwater camera. Surface net sampling was also undertaken for phyllosoma larvae of southern rock lobsters. Please note: This metadata record is a preliminary entry derived from information in the cruise plan and/or cruise report. Individual data types - which may span several cruises - will be indexed separately within this metadata system in due course.
