Increased Hatchery Production and Coded Wire Tagging of Interior Fraser Coho

The 2005 Pacific Salmon Commission (PSC) Report of the Expert Panel on the Future of the Coded Wire Tag Recovery Program for Pacific Salmon (PSC Tech. Report No. 18) identified shortcomings of coho indicator stocks due to low tag recoveries (Hankin et al. 2005). With the prolonged low marine survival rates of Southern B.C. (SBC) coho and subsequent reduction in fisheries, the coho stocks in SBC fail to obtain sufficient recoveries of coded-wire tags (CWTs). In addition to the increased sampling already implemented as part of the CWT improvement program directed towards coho, increasing the number of CWT’s applied to coho will provide better information regarding marine survival, distribution and exploitation rates of SBC coho.
