  • This dataset was collected by CSIRO Marine and Atmospheric division as part of its monitoring of the Northern Prawn Fishery. This is a key dataset for two separate prawn research projects ('NPF Monitoring' and 'New Catch Rates'), which have the following broad objectives: To map distribution and spatial contraction of prawns. To quantify the movement of banana and tiger prawns between the inshore and offshore waters of the Gulf of Carpentaria. Specifically this dataset is used: 1. To calculate the recruitment index each year for the main prawn species by region (January/February surveys). 2. To calculate the spawning index each year for the main prawn species by region (July/August surveys).

  • 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.
