NPF industry, AFMA management and CSIRO are concerned about declines in both spatial and the overall productivity of NPF tiger prawn fishery in recent years. It is thought that these declines are environmental/climate change - not fishing effort - driven. As well, stakeholders recognise that the NPF tiger prawn stock assessment model, whilst a 'cutting edge' model when first developed, has a number of deficiencies which are impacting on the model performance and impeding on the ability of the fishery to meet it's management objectives/ legislative requirements, the effective implementation of the tiger prawn harvest Strategy and Marine Stewardship Council (MSC) certification at risk. When the NPF tiger prawn stock assessment model was developed, the ability to conduct spatially-structured, environmentally or socio-economically based stock assessments was limited due to a lack of appropriate data (e.g. survey information) and computational requirements. whilst improvements to the model have been made over time, the NPRAG noted in February 2022 there has been a significant amount of work that has been undertaken that could enable a significant, if not a fundamental change to the model currently used. The extension of these activities through the workshop will enable discussion on the potential to better integration of these additional components and other new methods available to incorporate spatial and climate change considerations into the assessment model. The project will also assist the NPRAG and NORMAC to respond to the AFMA Commission's request for climate change impacts are considered at future by all RAGs and MACs .
