Measuring bycatch in the Moreton Bay prawn trawl fishery

Theme: Biodiversity and conservation science, Earth science and resources, Environmental management, Marine biology and ocean science

Description: This project undertakes the first dedicated bycatch sampling in the Moreton Bay otter bottom trawl in 20 years. This is the first independent data collection effort since Bycatch Reduction Devices became mandatory. The objective is to collect empirical data on current fishing practices and bycatch profiles. A key aim is to foster collaboration among commercial fishers, industry representatives, researchers, and managers to investigate bycatch issues in Australia's prawn trawl fishery, with a specific focus on Moreton Bay. By doing so, the project aims to raise awareness about problematic bycatch species (e.g., sea snakes, sharks, rays) and gain insights into when, where, and why they are prevalent. The project also seeks to identify and document existing bycatch reduction strategies employed by fishers, such as innovative configurations of Bycatch Reduction Devices and other nuanced and unrecorded operational tactics that could further reduce interactions with threatened or protected species. Additionally, it aims to document potential solutions and outline the necessary next steps for implementation. The project will draw insights from historical data, comparing contemporary bycatch profiles with information collected during the previous study in the early 2000s. The project strives to pave the way for collaborative, effective, and localized solutions that enhance the sustainability of Queensland's fisheries, while fostering better understanding among diverse stakeholders.

Additional Information: The field work for this project involves sampling onboard fishing boats in Moreton Bay. Trips are one night, two nights maximum. The student will be working with a research assistant who is a trained fisheries observer, and who also provides support with the logistics and liaising (e.g., organizing the field trips). Onboard sampling is physically challenging work, and the student needs to be prepared to spend time at sea and to work with commercial fishers. This work is tough but very rewarding, providing extremely valuable research experience and access to a network that includes government scientists, managers, and industry stakeholders.
