Surveys of inshore fish catches, fish diets, and habitat and abiotic factors were carried out off the coast of Albatross Bay, south of the Embley River mouth, in 1991 and 1992.

Surveys of inshore fish catches, fish diets, and habitat and abiotic factors were carried out in the Embley River Estuary, Gulf of Carpentaria, between 1986 and 1992.
-
Sampling was carried out in October 1993 and March 1994 to collect fish and juvenile prawns. Fish gut contents were examined. Sampling took place at two sites in the Embley River using gillnets, beach seines, rotenone, and beam trawls.

Surveys of offshore fish catches, fish diets, and habitat and abiotic factors were carried out off the coast of Albatross Bay, south of the Embley River mouth, in 1991 and 1992.

Logbook and observer data were obtained from state agencies WA Fisheries, NT DBIRD, QDPI, Logbook and observer data for fisheries in commonwealth waters were collected from AFMA and CMR - Hobart. Visits were also made to Museums to gather catch records and measure and photograph sawfish remains. This dataset is the result of a desktop study carried out by J. Giles whilst based at Cleveland. The spatial and biological catch data on sawfish was obtained from as many sources as possible in northern Australia; including commercial fisheries, research and recreational sectors and historical data sets. This also includes morphometric data on sawfish and rostra held in public and private collections.

Focussed habitat sampling of eight macrohabitats (defined by bottom type, soft hard or rough) in three mesohabitats (key study areas presenting a variety of shelf habitats described by fishers) using gillnets from a commercial vessel.six of the macrohabitats were located in Disaster Bay off southern NSW, the other two were in Victorian waters off Pt Hicks. Gillnets were deployed and retrieved at dawn and dusk giving near equal day/night soaking times. 17 deployments yielded 5,456 fish weighing over 5.5 t. For full details see Williams and Bax (2001).

Focussed habitat sampling of macrohabitats (defined by bottom type, soft hard or rough) in Gabo and Howe Reef mesohabitats (key study areas presenting a variety of shelf habitats described by fishers) using gillnets from a commercial vessel. Gillnets were deployed and retrieved at dawn and dusk giving near equal day/night soaking times. 15 deployments (1 trial soak and 14 sampling stations) yielded ~0.5 t fish.

Focussed habitat re-sampling of macrohabitats (defined by bottom type, soft hard or rough) in three mesohabitats (key study areas presenting a variety of shelf habitats described by fishers) using gillnets and traps from a commercial vessel. Gillnets were deployed and retrieved at dawn and dusk giving near equal day/night soaking times. 19 deployments yielded 6,457 fish and squid weighing nearly 4 t. Fish and crab traps were set during the day only, yielding 979 fish specimens (589 kg) and squids and hermit crabs weighing 673 kg in total.

This record describes the biological data collected on Rachel Cruise 04/1984. The data were obtained from the Western Australian NE coast and Joseph Bonaparte Gulf between April and May 1984. The dataset consists of length, sex, species identity data for sharks, mainly Carcharhinus tilstoni, Carcharhinus sorrah, Scomberomorus commerson and Thunnus tonggol, from gillnet and longline samples. This dataset was collected as part of the CSIRO Northern Pelagic Fish Stock Research Project.
