Data Sources and Methods for the Sustainable Fish Harvest Indicator
Caveats and limitations
- The Fishery Checklist program was initiated in 2007. A number of changes have been made as the program has developed. In particular, the stocks included in the Checklist program have changed and questions have been revised. A standard list of stocks and checklist questions were established in 2011. Year-to-year comparisons are possible between 2012 and 2011 results, but not to previous years.
- The Fishery Checklist is completed with the best available information. Given the challenges and expense of monitoring mobile fish in a large volume, comprehensive information is not always readily available.
- The Fishery Checklist summarizes information across a wide variety of species, management regimes, types of fisheries, geographic regions, and socio-economic contexts. Results should be interpreted with this in mind.
- For most stocks, including all groundfish, quota reconciliation is implemented for stocks where there are seasonal overharvests. In-season transfers allow exchanges to be made between license holders, such as an overharvest by one fisher being applied to the unused quota of another. When in-season transfers do not sufficiently cover overharvests, the overharvest is deducted from the harvest limit established for the following year.
