This four-year project funded by NSW DPI and the Fisheries Research and Development Corporation of the Australian government aims to assess, refine and encourage the adoption of industry-developed bycatch reduction technologies for Australian fish trawls, while maintaining target catches. Project Lead: Matt Broadhurst
NSW DPI and some commercial fishers have made substantial investments towards developing technical modifications to various fishing gears, and especially prawn trawls, to mitigate bycatches and/or habitat impacts and/or improve efficiencies. The outcomes of these investments are being realized via the refinement and promotion of relevant modifications among key fisheries during a four-year project. Project Lead: Matt Broadhurst
The NSW SMP has been delineated a ‘key threatening process’ for several marine species. The project is using state-of-the-art genetic tools and technology to determine how sharks interact with bather-protection nets and their post-release survival, whilst trialling new tools to reduce bycatch. Project Lead: Victor Peddemors
Sharks are notoriously easy to overfish, yet they comprise substantial catch in NSW waters. This project incorporates innovative technologies to determine the biology and movements of caught elasmobranchs, plus the survival of released unwanted catches and the impacts of fishing on shark and ray populations. Project Lead: Victor Peddemors
This project seeks to better understand factors influencing shark-human interactions and, incorporating this insight, use new technologies to increase protection for bathers from shark interactions while minimising harm to sharks or other animals. Aerial surveillance includes trials of drones, blimps and helicopters. In-water surveillance incorporates testing of eDNA, sonar, real time detection and communication of tagged sharks using specialized (VR4G) listening stations. Technologies for deterring of sharks include various personal deterrents, SMART drumlines, physical and electrical barriers, and necromones. The people behind the research include Shark SMART scientist Project Lead: Paul Butcher
This multi-faceted project aims to quantify the populations sizes, long-term movement patterns and diets of white, tiger and bull sharks to better understand their ecology and risk of interactions with humans. Project Lead: Paul Butcher
