FN0895-Salmon - Fraser River Sockeye and Pink Update - Areas 11 to 29 - August 31, 2017
The Fraser River Panel met on Thursday, August 31, 2017 to receive an update on the migration of the Fraser sockeye and pink runs to date and review the status of migration conditions in the Fraser River watershed. Test fishery sockeye catches have fluctuated considerably in the Area 12 purse seine test fishery while Area 20 purse seine and in-river test catches have declined and stabilized at very low levels. Based on the purse seine test catches in the two approach areas the projected sockeye diversion rate through Johnstone Strait has increased to 97% compared to the pre-season forecast of 51%. The most recent DNA samples taken in the marine purse seine test fisheries show sockeye stock compositions in Area 20 of approximately 1% Early Summer, 53% Summer and 45% Late run stocks. In Area 12, the purse seine stock composition was 2% Early Summer, 52% Summer and 46% Late run stocks. The decrease in proportion of Early Summer run stocks combined with the increase in the proportion of Late run stocks is consistent with current run timing assumptions. The most recent in-river stock identification samples from the Whonnock test fishery are showing stock proportions of 7% Early Summer, 71% Summer and 21% Late run stocks. The low proportion of Late run stocks in recent samples is suggesting that some late run fish may be holding off the river, which would be consistent with pre-1996 behavior. Daily sockeye escapement estimates are now being generated based on the Whonnock gillnet test fishery catch per unit effort information as pink salmon abundance is causing issues with Mission based estimates. Daily sockeye estimates during the past 4 days have ranged between 10,100 and 25,800. The total estimated sockeye escapement as of August 30 is 1,240,500. Hell's Gate observations of sockeye have fluctuated recently on a declining trajectory. During the Fraser Panel call yesterday no changes were made to the run size for any sockeye run timing groups. At the current run size for Early Summer, Summer and Late run sockeye, there is no TAC available and as such only fisheries with minimal impact on sockeye are being considered at this time. The estimated escapement past Mission of Early Stuart, Early Summer, Summer and Late run sockeye as of August 30 is 46,400, 161,000, 940,100 and 93,000 fish, respectively. On August 30, the Fraser River water discharge at Hope was 2,025 cubic metres per second, which is approximately 20% lower than average for this date. The water temperature of the Fraser River at Qualark Creek on August 30 was 18.4° Celsius which is 1.4° Celsius higher than average for this date. The forecast is for water temperatures to increase to 19.0° Celsius by September 5 as air temperatures are predicted to increase in the next several days. Due to the very low discharge levels, water temperatures are highly influenced by air temperatures. For pre-season planning purposes the Fraser Panel had adopted management adjustments for Early Summer, Summer and Late run sockeye that reflect the forecast water temperature and discharge conditions based on the May and June information for Early Summer and Summer run sockeye, and anticipated river entry dates for Late run fish. Due to the very poor return of Early Summer and Summer run stocks they are now being managed based on a Low Abundance Exploitation Rate (LAER) limit and as such there will be no modifications to the in-season management adjustments for these groups. Management adjustments are additional fish that are set aside from identified harvest levels and allowed to migrate upstream in an attempt to assist in achievement of identified spawner objectives for the different run timing groups. No in-season changes to the management adjustment are expected for Early Stuart, Early Summer, Summer and Late run groups in 2017. Test fishery catches of pink salmon in the two approach areas continue to fluctuate at lower levels in recent days with larger catches occurring in Area 12. During the Fraser Panel call on Monday a provisional pink run size of 4.8 million fish with August 24 timing through Area 20 was adopted for management purposes. The most recent pink stock identification samples analyzed for Areas 12 and 20 purse seine test fisheries indicate Fraser origin pink salmon comprise 68% and 70%, respectively. Based on the most recent purse seine test catches the estimated diversion rate through Johnstone Strait for Fraser pink salmon has increased to 72% compared to the historical median of 50%. Run size and timing updates for Fraser pinks are likely to be made in the coming weeks. Based on a pink run size of 4.8 million the US total allowable catch is calculated to be 97,000 fish. As such the US proposed both Treaty Indian and All Citizen fisheries over the next several days which Canada approved. See the PSC fishery regulations for details of each fishery. In the All Citizens fishery all sockeye will be released while in the Treaty Indian fisheries sockeye can be retained for Ceremonial and Subsistence purposes. Sockeye impacts for these fisheries were projected by the PSC staff to be in the 300 to 400 fish range for the proposed openings. Earlier in the season First Nations food, social and ceremonial sockeye fisheries were restricted by a 4 week window closure protecting Early Stuart and the earliest timed Early Summer run stocks with limited fishing opportunities in-river directed at Chinook salmon. These Chinook directed fisheries may continue to occur in both the lower and mid-river fishing areas up to Lillooet and in portions of the Thompson River drainage, until the coho window closure comes into effect. Areas in the Fraser River upstream of Lillooet have been severely impacted by the numerous forest fires this season which have prevented many First Nations from any fishing to date. As a result the department is allowing for limited sockeye directed fishing opportunities for a modest number of sockeye in a number of locations as no other species of salmon are available for harvest in these areas. In inside coastal waters, limited fishing opportunities directed on pink, chum and chinook have been permitted with the retention of dead sockeye being permitted. Another limited fishery is planned over the weekend in the lower Strait of Georgia directed on pink salmon. Sockeye encountered and kept or released in all these fisheries are accounted for as part of the Low Abundance Exploitation Rate limits. Food, social and ceremonial fishers in marine approach areas as well as the Fraser River are requested to check for the opening times and any restrictions in their local area. The Department is receiving questions regarding the possibility of recreational fishery openings for chinook and/or pink salmon in the Fraser River. At this time management measures in place are aimed at limiting impacts on Fraser sockeye while allowing First Nations food, social and ceremonial fisheries, directed on other species, to occur. Recreational fisheries for salmon in the Fraser River are not anticipated to open in advance of the upcoming Labour Day weekend. DFO will continue to monitor the migration of sockeye through the marine areas and the Fraser River and will consider an opening for pink salmon when it is determined that impacts of an in-river recreational fishery would be minimal for sockeye. As Late Run sockeye can demonstrate holding behaviour in the lower river and off the river mouth, such an opportunity is likely not to occur in the immediate future. Due to significantly reduced FSC harvest for First Nations this year, with very low harvests of both sockeye and chinook to date, DFO is not considering opening additional recreational chinook fisheries in the river at this time to provide for priority access for First Nations FSC fisheries. For information on current recreational fishery opportunities for chinook in other areas please see the Department's web-site at: http://www.pac.dfo-mpo.gc.ca/fm-gp/rec/index-eng.html The fifth upstream escapement report was released by DFO on August 31. The Early Stuart sockeye program is now complete. Enumeration programs are underway in a number of Early Summer and Summer run systems with low numbers of fish to date. The Scotch Creek counting fence was installed on August 9 with 2,288 sockeye counted to date while the counting fence at Sweltzer Creek (Cultus) was installed on July 31 with 68 sockeye observed to August 22. Spawning channel counts in the Nadina River and Gates Creek are 1,005 and 1,440 respectively. Didson programs in the Chilko and Quesnel Rivers have enumerated 80,665 and 21,181 sockeye respectively to date while an additional Didson program was recently initiated in the Stellako River. In addition there are ongoing cyclic visual observation programs being conducted throughout the Fraser watershed where more intensive programs are not being conducted. Fish condition in most areas has been reported to be good so far this year. The next in-season meeting of the Fraser River Panel is scheduled to occur on Tuesday, September 5, 2017.
