Salmon Coded-Wire-Tag Fishery Sampling -- Location Data

The Coded-Wire Tag (CWT) database contains the Release, Recovery, Catch/Sample, and Location data. CWT is the Pacific Region’s centralized Oracle database that holds adult salmon escapement data.

Location Data

The geographic locations of release, sample, and specific recovery of fish are also assembled by specific location reporting agencies. Collectively, these are called Location data and are submitted to the RMPC along with all other classes of data. There are five types of locations. Within each type of location, the location record is uniquely identified coastwide by a 19-character Location Code. That code is associated with a textual description of the location and a geographical reference to the location.
