Observers have collected sockeye samples from the Area 4B/5 gillnet test fishery near Neah Bay annually for the last six years. Samples from Area 20 on the Canadian side of the Strait are assumed to represent stock proportions in catches on the U.S. side of the Strait. We propose to compare the DNA results already collected on approximately the same dates. This comparison will confirm or disconfirm the assumption that Area 20 stock composition estimates serve as accurate proxies for the U.S. catches in the Strait.
