This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "Sawfish bycatch mitigation workshop for northern Australian fisheries". The project will coordinate a workshop with state and commonwealth fishery managers, fisheries biologists, researchers, DAWE recovery plan team, NGO’s and traditional owners to understand the issues around sawfish bycatch and develop methods to improve data recording to enable estimates of sawfish catch rates. The long-term goal of the meeting is to develop a nationwide monitoring strategy for sawfish that will enable DAWE to assess the status of sawfish and assess the effectiveness of the recovery plan actions and whether mitigation measures are having an impact on sawfish populations. # Outputs • Final technical report with analysed data and a short summary of recommendations for policy makers of key findings [written] • A graphical summary of the workshops was developed by Dr Sue Pillians [images].

This record provides an overview of the NESP Marine and Coastal Hub small-scale study - NESP Marine and Coastal Hub scoping study: New approaches to monitoring. Observations of marine species have rapidly diversified over the last decade with increasing numbers of observations collected either through citizen science programs or opportunistically by citizens and then submitted into public databases. The expectation of citizens contributing those data is that the data is incorporated into formal analyses and utilised either for scientific or management purposes, with outcomes that improve current understanding and conservation of marine species. Further, there is increasing reliance on more informal and publicly driven approaches to the collection of observations given the costs of conducting formal surveys particularly if accessing remote regions, or if repetition of collection (across seasons or years) is needed. Integrating opportunistic observations with more formally collected observations (e.g. those collected through robust survey designs), however, is not straightforward. Traditional approaches to estimating population abundance, changes in species assemblages, abundances and distributions through time require some understanding of the effort associated with those observations and how that effort is also distributed through time; information that is missing from opportunistic observations, given the nature of those observations. Further, many opportunistically collected datasets do not meet the statistical assumptions of many analytical approaches that might be applied to scientific datasets. As a result, opportunistic observations are underutilised at present and are largely only used qualitatively within research applications. To take full advantage of this rapidly expanding resource and ensure that efforts associated with the collection of these observations are not wasted, methods that can integrate opportunistically collected data with scientific datasets are needed. This project represents the first stage in developing integrative methods. It will bring together data holders, quantitative ecologists and statisticians to explore potential approaches that might be applied to facilitate the integration of opportunistic datasets with scientific datasets. In doing so, it will identify what datasets might be best suited to the development of integrative approaches (and what might not) and outline a pathway for developing those methods that could be implemented through a future project Planned Outputs • Workshop • Final technical report with analysed data and a short summary of recommendations for policy makers of key findings [written]
