Prawn larval density recorded from stepped oblique bottom to surface plankton tows in Albatross Bay. Monthly cruises were carried out between March 1986 and April 1992, at twenty-one stations in Albatross Bay, Gulf of Carpentaria. Prawn larval densities were measured and salinity-temperature profiles taken. This data has 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

Prawn larval density recorded from stepped oblique bottom to surface plankton tows in Albatross Bay, Gulf of Carpentaria. 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 grids 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. The 'conversion factor' used to calculate the non commercial and commerical splits was derived from a spreadsheet containing Metapenaseus and Penaeus species. Commercial Metapenaeus spp. are M. endeavouri and M. ensis. The dataset was used to derive a commercial conversion factor. Thus the component of Metapenaeus spp. that are commercial; "Commercial Metapenaeus Prawn Larvae density" = 'conversion factor" x "total Metapeneaus prawn larval density" Conversion factor value 0.22. This was derived from all GOC data and checked for depths 5-20m, 20m, 30m, 30-40m, and 50-60m. It was found that the ratio of commercial Metapenaeus spp. to non-commercial Metapeneaus is constant with depth across the GOC.

Data showing total zooplankton biomass (dry weight) from stepped oblique bottom to surface plankton tows for both the wet season and dry season in Albatross Bay. Biomass estimates from two mesh sizes. Nine cruises took place between 1975 and 1977 on chartered boats and the "Kalinda". Prawn larval biomass, prawn larval densities and total zooplankton were measured in several transects across the Gulf of Carpentaria.

Between March 1986 and April 1992, monthly cruises were carried out at twenty-one stations in Albatross Bay, Gulf of Carpentaria. Prawn larval densities were measured and salinity-temperature profiles taken. Prawn larval density from stepped oblique bottom to surface plankton tows. Net sizes were 142 or 140m mesh, 250micron mesh with a 0.5x0.5 square frame, stepped-oblique tow. In this dataset Penaid prawn counts were recorded to species level for the genus Penaeus only, for larval stages Mysis 1-3. (Identification was not possible for other larval stages).

Between March 1986 and April 1992, monthly cruises were carried out at 21 stations in Albatross Bay, Gulf of Carpentaria. Prawn larval densities were measured and salinity-temperature profiles taken. Prawn larval density from stepped oblique bottom to surface plankton tows. Net sizes were 142 or 140 m mesh, 250 micron mesh with a 0.5 x 0.5 metre square frame, stepped-oblique tow. In this dataset Penaid prawn counts were recorded to genus level for all larval stages.

Monthly cruises were carried out between March 1986 and April 1992, at twenty-one stations in Albatross Bay, Gulf of Carpentaria. Prawn larval densities were calculated from stepped oblique bottom to surface plankton tows. Salinity-temperature profiles were also recorded. There is also data showing zooplankton biomass in Albatross Bay for both wet and dry seasons.

Prawn larval densities were calculated from stepped oblique bottom to surface plankton tows, deployed during monthly cruises carried out between March 1986 and April 1992, at twenty-one stations in Albatross Bay, Gulf of Carpentaria. Penaeid prawn counts were recorded to genus level (Penaeus spp.) for all observed larval stages. Salinity-temperature profiles were also recorded during the cruise.

Prawn larval densities were calculated from stepped oblique bottom to surface plankton tows, deployed during monthly cruises carried out at twenty-one stations in Albatross Bay, Gulf of Carpentaria. Cruises were undertaken between March 1986 and April 1992. Penaeid prawn counts were recorded to species level (Penaeus spp.) for all observed larval stages. Sampling used a stepped-oblique tow, using a 0.5 x 0.5 square metre frame with 140-142 micron mesh. Salinity-temperature profiles were also recorded during the cruise.

This mapset shows prawn larval distribution of commercial species pooled by species group and season for Albatross Bay. The map base data was produced by CMR stepped oblique bottom to surface plankton tows. Monthly cruises were carried out between March 1986 and April 1992, at twenty-one stations in Albatross Bay, Gulf of Carpentaria. Prawn larval densities were measured and salinity-temperature profiles taken. 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.
