Valuing WA's smaller commercial fisheries across the supply chain provides crucial insights into their economic importance. It enables informed decision-making, equitable resource allocation, and sustainable development. The study's methodology can be replicated for other fisheries, expanding our understanding of the economic impact of different fishing operations. Collecting primary data ensures accuracy and reliability, while the extension of practitioner guidelines offers a standardized framework for assessing supply chains and economic contributions. This promotes transparency, accountability, and targeted interventions. Overall, valuing these fisheries fosters collaboration, supports local economies, and ensures the long-term viability of the industry.
