Weipa Juvenile Prawn Data 1981-1982

공공데이터포털

Sampling of juvenile prawns took place between 1981-1982. These samples were mainly taken from the Embley River and Albatross Bay region. Samples were collected using beam trawls, plankton nets and set nets. Data recorded include species and length frequency.

Embley River Prawn Predation Data 1993-1994

공공데이터포털

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.

Prawn Recolonisation Data, Gulf of Carpentaria 1984-1995

공공데이터포털

Juvenile prawn samples were collected by beam trawl at a number of sites between the Vanderlin Islands and Rose River (Numbulwar), Gulf of Carpentaria, to investigate the recolonisation of sand and seagrass habitats following Cyclone Sandy.

Albatross Bay Adult Prawn Data 1986-1992

공공데이터포털

Adult prawn species, size, sex, reproductive stage, moult stage, and parasites were measured at 20 stations in Albatross Bay, Gulf of Carpentaria. Sampling was carried out monthly, around the new moon period, between March 1986 and May 1992. The projects objectives were: - To carry out a trawl survey of prawn species distribution, size distribution, population density and reproductive status in the study area - To carry our sampling for larval prawns at selected stations. - To sample for phytoplankton species composition and chlorophyll a levels at selected stations.

Groote Eylandt Nearshore Fish Study 1989-1990

공공데이터포털

Surveys of inshore fish catches, fish diets, and habitat and abiotic factors were carried out off the coast of North-west Groote Eylandt, Gulf of Carpentaria, in 1989 and 1990.

Tropical Prawn Project Prawn Trawl Data c1975-1979 (Redfield Data)

공공데이터포털

Prawn trawl data from Weipa, East and South East Gulf of Carpentaria in the late 1970s. The main objective was to ascertain the distribution and abundance of each of the main commercial and some non-commercial penaeid species. The main data collection was performed off the Judy B with cruises repeated every month for 13 months; some other vessels were involved at different times (Kalinda, Raptis Pearl, Sprightly). Trawling was conducted at night and consisting of 30 minute shots. All prawns were sorted by species (general codes used) and sex, but no weights were recorded. Catch rates were expressed as number of prawns caught per net per hour. There were more than four sampling plans.

Southern Surveyor Voyage SS 03/2005 Prawn Trawl Samples

공공데이터포털

The dataset comprises catch records of demersal fish and invertebrates from prawn trawl deployments completed on research voyage SS 03/2005. The survey design was a natural experiment (i.e. control-impact, but not before-after) to test the long-term, broadscale effects of prawn fishing on non-target species and habitats. Deployments were stratified by fishing intensity (three strata) and day/night. The survey was repeated in three regions: (a) north of Groote Eylandt, (b) north-east of the Vanderlins, and (c) north of Mornington Island. The number of deployments completed as part of the natural experiment was 124. Outside of the natural experiment, an additional 31 deployments were completed at dawn or dusk for diet analysis and an additional two deployments were completed for other reasons.

Embley River Enclosure Data 1993-1994

공공데이터포털

Juvenile tiger prawns were collected by beam trawl in the Embley River, Gulf of Carpentaria in October 1993, March 1994 and October/November 1994. The following parameters were measured: prawn numbers, carapace length, species, seagrass, biomass, salinity, temperature and depth. Field experiments were carried out using enclosure nets.

Mapset: Prawn Larval Distribution in the Gulf of Carpentaria for Wet and Dry Seasons

공공데이터포털

Maps showing prawn larval distribution of commercial and non-commercial species during both the wet and dry seasons in Albatross Bay. The data was recorded from stepped oblique bottom to surface plankton tows, 140-142um nets. Nine cruises took place between 1975 and 1977 on chartered boats and the "Kalinda". Prawn larval biomass and densities were measured in several transects across the Gulf of Carpentaria, as well as total plankton biomass. These maps have been produced by CSIRO for the National Oceans Office, as part of an ongoing commitment to natural resource planning and management through the 'National Marine Bioregionalisation' project.

MacArthur River Mines Prawn Data 1994-1996

공공데이터포털

Beam trawl surveys of juvenile prawns were carried out between the Vanderlin Islands and Rosy Creek, Gulf of Carpentaria to investigate the impact of dredging by MacArthur River Mines.
