| Title: | Catch per unit, CPUE, of Chum salmon collected from small vessel Qualicum Producer in Strait of Juan de Fuca from 2016-09-27 to 2016-10-31 (NCEI Accession 0284355) |
| Abstract: | Through the initial work on the ChumGEM reconstruction model, it was very apparent that the diversion of Chum salmon stocks through the southern route (Strait of Juan de Fuca) was a significant gap in our information needed to populate the model. Currently the model structure is available to incorporate this information but the assumptions on the migration pathways being used require investigation and validation. The purpose of this project was to work towards addressing that data gap by sampling this migration route in both US and Canadian waters to determine: • The spatial and temporal stock composition of Chum salmon migrating through the Southern Diversion route, • Provide sampling platform for stock identification, migration rate studies etc. • Develop time series of Catch per Unit effort data to pair with the Johnstone Strait Test Fishery to determine diversion rate of various Chum populations. The first year of this multi-year program was initiated in 2016. The program began as planned on September 27th and ran until October 31st. A total of 104 sets were completed (44 in Canadian waters and 60 in US waters). A total of 1,471 Chum were encountered and 1,024 were sampled for stock id and other biologicals. The catch information demonstrated a later timing than originally expected, also observed in the Johnstone Strait Test Fisheries, with the highest Chum Catch per Unit Effort (CPUE) occurring in week 44. Over the period of the program, Chum CPUE was higher in US waters than in Canadian waters except in the first week. Stock composition information demonstrated that Canadian stocks dominated the samples early in both US and Canadian fishing areas. In Canadian waters US stocks increased in composition later in the program and were prevalent throughout the sampling in US waters dominating the mixture after week 41. Stock timing and distribution differences were observed and this new information has improved our understanding of stock composition and timing through the Strait of Juan de Fuca. This cruise is U.S. State Department MSR U2016-028 as part of the World Data Service for Geophysics and Oceanography. Final cruise report is in PDF. |
