Herring Permanent Spawn Transects (geodatabase) - used for herring spawn survey program and spatial analysis/presentation of spawn data from Herring Stock Assessment Database (including creation of spawn polygons).

Pacific Herring spawn index data for British Columbia from 1951 to present. Note that the spawn index is a relative index of spawning biomass. In addition, “NA" indicates that data are unavailable because they are either incomplete or withheld; contact the custodian for more information. For the "Region" column specifically, "NA" indicates that the location is outside stock assessment region boundaries. There are a few caveats to consider when interpreting Pacific Herring spawn index data, which are discussed in the technical report (see supporting documents).
