"Current run size estimates of Fraser River Summer Run sockeye salmon combined with record water temperatures in the Fraser River have resulted in no allowable harvest and a conservation concern. The Department's priorities are
to ensure that there is sufficient sockeye returning to the spawning grounds."
The species of concern right now is sockeye salmon, and at the current level no allowable harvest is available for the recreational sector and by-catches need to be kept below a certain %. When resource managers conclude that % cannot be kept within the limit, the fishery closes, as you can see in this case. When the fishery opened in early August, Fisheries and Oceans Canada performed flight count in the Lower Fraser River to determine the % of anglers who are flossing/not fishing selectively. Preliminary results show that on opening day, 71% of participants were not fishing selectively. It was a lot better a few days after that, 38% were not fishing selectively. Last weekend, 61% were not fishing selectively, so the % went up again. By doing so, resource managers concluded that too many sockeye salmon were being incidentally caught, so the fishery closes. Obviously the tidal portion and mouth of the Fraser have very few participants who intercept sockeye salmon, but once the number of incidental catches reach the limit and no more by-catches are allowed, a total closure is needed.
The same scenario played out two years ago if people can remember that. Pink salmon fishery opened in early September once summer run sockeye salmon passed through, so we can expect the same to occur again. The unfortunate part is that some pink salmon opportunities will be missed out in late August, beside the excellent chinook salmon fishing opportunities right now.
