  • This dataset was collected to calculate optimal seasonal opening dates for the commercial fishery and to provide other management advice, by undertaking size sampling of pre-season and in-season banana prawns (F. merguiensis and F. indicus). In-season sampling of commercial catch on commercial trawlers (1983 - 1985) was supplemented during the season by data obtained from quality control staff at KFV Fisheries Pty Ltd. Sampling was organized for pre- and in-season searching and sampling voyages and prawns were sampled and measured from as many trawlers as possible.

  • 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.

  • This data was collected to obtain base information for prawn management advice. Data were collated by 6 nm grid squares species, sex and size distribution (carapace length) of prawns in the commercial catch 1988 - 1990 inclusive. Also collated were turtle distribution in catches in 1989. All samples were taken and processed by CSIRO trained commercial trawl boat crews and presumably all samples were taken from areas of high abundance at that time. The fishing times over this period were 15 April to 22 June and about 1 August to 30 November.

  • This dataset was collected mainly to provide banana prawn length-frequency data by undertaking size sampling of commercial catches of banana prawns (P merguiensis). The aim was to calculate optimal seasonal opening dates for the commercial fishery and to provide other management advice. Length-frequency data for other prawn species was also provided.
