In British Columbia we release approximately 40 million chinook salmon. I'm not sure of the entire amount if you include coho, but it is 40 million chinook. Of those, approximately 10% or less are marked.
The State of Washington releases around 150,000 chinook a year. All of those or the bulk of those end up spending a good portion of their lives in British Columbia waters. It marks 100% of its chinook.
