Salmon Coded-Wire-Tag Fishery Sampling -- Recovery 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.

Recovery Data

When tags are removed from fish and decoded, the tag is linked to the specific location of catch, date of catch, fishery, and other related biological data. Where possible, the ratio of the number of fish sampled to the total catch is multiplied by the total number of tags extracted to form the Estimated Number of fish. These data are collected by sampling agencies for submission to the RMPC on a yearly basis along with Catch/Sample data.
