The interdisciplinary team behind the Measuring the Effects of Catch Shares project compiles and analyzes data on ecological, economic, social, and governance changes in selected catch share fisheries. We provide objective reports showing changes that have occurred in fish stocks, fishermen, fishing-related businesses, and local communities before and after implementation of catch shares.

The purpose is to make high-quality, unbiased scientific indicators of changes in these fisheries easily accessible to everyone. We offer unprecedented ways of exploring and interacting with fishery data. Now anyone can delve into the science to answer their own questions about the catch share programs and to engage in well-informed decision-making.

The Measuring the Effects of Catch Shares project does not advocate for or against catch shares.
