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.

Change in recreational fishing expenditures associated with project site visitation Economic Activity - Recreation and Tourism (R) 2 Project

Estimate of total recreational fishing expenditures due to the project compared to baseline of recreational fishing expenditures in surrounding area, calculated as the number of recreational fishing trips to the project site (estimated from random sampling counts as part of structured monitoring) multiplied by the average trip expenditure (from NOAA FEUS 2018 Report).

Change in economic activity from recreational fishing Economic Activity - Recreation and Tourism (R) 2 Program

Jobs, labor income, gross state product, and total industry output modeled annually at a county to regional level. Angler surveys will account for the difference in activity associated with a restoration project, which would then be used as input into the economic impact analysis (see Texas Half Moon Reef example [PDF]).
