Data Sources and Methods for the Sustainable Fish Harvest Indicator

5. 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 only possible for years between 2011 and 2014.

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 licence 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.
