The Global Aquaculture Performance Index is a tool to empower seafood industry leaders and policy makers to make informed decisions about the environmental costs and benefits of farmed marine finfish. GAPI uses a well-established statistical methodology to provide a rigorous and objective evaluation of the environmental performance of marine aquaculture globally. The methodology is based on the Environmental Performance Index (EPI) approach developed by a team of environmental experts at Yale University and Columbia University , which has been revised biennially since 2006.
The species-country focus of the 2010 GAPI yields results that are most relevant for comparisons of performance across species and countries. Future applications of the GAPI framework will include the development of a farm-level performance index and an evaluation tool to benchmark the environmental performance of current and future aquaculture standards.
