SNAPP TEAM:Data-limited Fisheries
Can new, inexpensive science-based tools for assessing and managing data-limited fisheries be widely implemented to help end overfishing?

Overfishing threatens many of the world’s fish stocks — and the millions who rely on fish for their food and livelihoods. Reliably managed fisheries suffer less overfishing, but more than 90 percent of Earth’s fisheries currently lack effective management. Scientists have developed innovative approaches to assess and manage fisheries despite limited data and resources. Managers and scientists need to work together to ensure widespread adoption of these approaches and bring them into the mainstream.


OUR APPROACH: This group assembled fish stock assessors, social scientists, ecologists, and marine conservation practitioners to evaluate the problems of data-limited fisheries and build a framework to solve it.

Team Critical Challenges: Ocean Sustainability, Food and Freshwater


FishPath is a decision-making software application that provides fisheries managers with a step-by-step guide to select monitoring, assessment, and management methods for their fishery. It is now the most comprehensive toolkit for data-limited fisheries. Researchers launched this tool during pilot projects in Peru and Kenya, and its successful use has sparked interest by other governments around the world. If widely applied, FishPath will help ensure that nations can adequately assess and manage their fisheries, thereby improving both conservation and economic outcomes.




“The user-friendly FishPath software facilitates direct and process-oriented engagement with fisheries stakeholders.”

– Carmen Revenga, Project co-Leader
