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.

Embley River Invertebrate and Fish Settlement Data 1993-1994

공공데이터포털

Surveys of of post-larval and juvenile animals, mainly fish, prawn and other crustaceans, were carried out in 1993 and 1994. Samples were collected using artificial settlement units in the Embley River estuary, Gulf of Carpentaria.

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.

Weipa Juvenile Prawn Data 1986-1992

공공데이터포털

Fortnightly sampling of juvenile prawns took place over six years (1986-1992). These samples were mainly taken from the Embley River and Albatross Bay, plus one set that were taken from the Wenlock and Archer Rivers. Samples were collected using beam trawls, plankton nets and set nets. Data recorded include species and length frequency. As part of this project, monthly temperature and salinity measurements were also taken from transects in the Embley River. These data are often referred to as the "Embley River Hydro Dataset".

Groote Eylandt Juvenile Prawn Data 1983-1989

공공데이터포털

Seagrass aerial surveys were used to produce maps of the Groote Eylandt area. Samples of juvenile and sub-adult prawns were taken by beam trawl at Groote Eylandt, Blue Mud Bay and Sir Edward Pellew Islands under various sampling regimes between 1983 and 1989.

Embley River Fish Study 1986-1992

공공데이터포털

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.

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.

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.

Gulf of Carpentaria Adult Prawn Data 1995

공공데이터포털

Adult grooved tiger prawns (Penaeus semisulcatus) were caught in prawn trawls during one transect of the Gulf of Carpentaria on the FRV Southern Surveyor. The catches were used to assess offshore migration of the species. Data collected include length frequency, sex and gonad stage. Data were collected using 39 paired Florida Flyer trawls centred on 6nm grids across approximately 13 sites. The sites are spaced some distance apart along the cruise track (a transect from Weipa to N Groote and back to Weipa). The AusTED and standard codend were compared in these trawls, and the same data were also to be used monitor the distribution of Penaeus semisulcatus across the Gulf. Problem shots were retrawled when possible to meet the experimental design. Nine were abandoned due to lack of time.

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.
