Back in the mid-80s WDF proposed closing all of the approach waters for Fraser sockeye except areas 7 and 7A because the proposed areas had lots more US-origin fish for bycatch. At a public hearing on the proposal on commercial guy noted that one of the proposed closure areas was his favorite spot to fish. I pointed out that in the last 5 or 6 6 years there had been one landing for about 5 fish from that area. He was "smart" enough to know that the bycatch he caught, and there a lot of Chinook there, would not count against the NI share if reported from waters dominated by Canadian fish.

Like I said, the quality of management is directly related to the quality of data.
