Here is the latest Pacific Salmon Commission news release from Aug. 1 on the state of summer sockeye headed to the Fraser River in southern British Columbia:
The Fraser River Panel met Aug. 1 to review assessment data on Fraser River sockeye salmon. The migration of sockeye through marine and lower Fraser River assessment areas as well as past the Mission hydroacoustic site has increased over the past week. The observer at Hells Gate has reported steady sockeye migration over the past several days with fish being in good condition.
DNA analysis of a fish sample collected from a recent Area 12 purse seine test fishery indicated Fraser sockeye contributions by stock group were approximately 21% Early Summer-run, 66% Summer-run sockeye and 13% Late-run. Early Summer-run proportions have been dominated by the Early Thompson stock-group in recent samples. Increasing proportions of both the Late Stuart/Stellako and Chilko/Quesnel stock groups have been observed and Late-run proportions have been dominated by the Late Shuswap group in recent samples.
Assessment of Early Stuart sockeye is nearing completion with a total of 218,000 escapement past Mission as of July 31st.
Assessments of Early Summer-run sockeye abundance are ongoing. Most components of the Early Summer-run group have been represented in samples from marine and in-river test fisheries. An in-season update to earlier-timed components of this run-timing group (e.g. Chilliwack, Pitt, Bowron, Nadina, Gates) should be available next week. Updates of run sizes for the more abundant later-timed components (i.e. Early Thompson) should be available in early August after their peak migration through marine areas. The estimated escapement of Early Summer-run sockeye past Mission through July 31 is 176,200 fish.
Assessments of Summer-run sockeye abundance are beginning. Updates to the run size of the Summer-run group should be available in mid-August after their peak migration through marine areas. The estimated escapement of Summer-run sockeye past Mission through July 31 is 214,800 fish.
On July 31, the Fraser River water discharge at Hope was 4,075 cms, which is 11% below the average for this date of 4569 cms. The temperature of the Fraser River at Qualark Creek on July 31 was 18.4C, which 0.7 C above average for this date. The first in-season update to the Early Summer-run management adjustment should be available in about 10 days (5 days after their peak migration through marine areas). Management adjustments are additional fish that are allowed to escape upstream to help achieve spawning escapement targets for Fraser River sockeye.
