Change in economic activity from project associated commercial fish harvest Economic Activity - Finfish/Shellfish Harvest (R) 2 Program

Jobs, labor income, gross state product, and total industry output modeled annually based on NOAA commercial harvest data and state data (e.g. Florida commercial fisheries) for relevant species. Change in economic activity from commercial fish harvest could be due to changes in target populations or areas closed to harvest due to water quality issues. Reporting harvest and revenue (intermediate outputs for calculating this metric) may also be useful to give a full picture on how commercial harvest patterns have changed in response to the project.
