5. Reports from the Sub-Committee and Working Groups
   
   
(a)    Science Sub-Committee (SSC)
 

The first meeting of Long-term Research and Monitoring Project was held on April 79, 2008, under the chairmanship of B. Riddell.  In the first day, participants made short presentations that identified linkages between climate and the population ecology of Pacific salmon.  In day two, each participant summarized their views on regional and international monitoring and long term research issues.  There was extensive discussion on day two that highlighted some important and common issues such as priorities of research and monitoring subjects, and management of international database.  Day three was used to continue the discussion and to focus on one potential international project.  The concept of an International year of the salmon received strong support.  The discussion of the participants will be used to draft a preliminary long term research and monitoring plan.

There was a brief discussion of the bibliography that was distributed prior to the meeting.

There was general agreement that this first meeting accomplished the objective of using the existing knowledge of climate impacts on Pacific salmon to begin identifying research and monitoring priorities in order to improve Pacific salmon forecasts.

 

(b)    Working Group on Stock Assessment (WGSA)
 

The Working Group on Stock Assessment discussed the following three items:

1) up-dating the historic catch data, 2) up-dating the catch and salmon release data on the NPAFC website, and 3) the development of a working paper on the state of Pacific salmon in the NPAFC member countries (up-date of NPAFC Doc. 723).

Catch statistics through 2006 have been provided by Korea, Russia, Japan, and the United States (Alaska and the southern US states).  Data provided for the southern U.S. states are considered preliminary for the 2006 sport fisheries as the reporting remains incomplete Canada reported that it had completed its review of past catch data and will be reporting on that review later.

The Secretariat requested assistance of the working group to update the statistical summary available on the NPAFC website.  B. Riddell (Canada) volunteered that it would be most efficient if he and J. Irvine (working group chair) completed the tables and graphs identified by the Secretariat and circulate them to other members for verification.  The final data would be provided to the Secretariat for inclusion in the website.

Most discussion was related to the lack of progress on the development of an expanded report on the state of Pacific salmon in the North Pacific Members of the working group had agreed at the 2007 Annual Meeting to include additional data related to the state of salmon (e.g., numbers of spawning salmon, estimates of marine survival rates, etc) and to categorize the state of salmon from regions of the North Pacific However, no progress has been made to-date.  To assist in the development of an expanded revision of Doc. 723, B. Riddell recommended that he and J. Irvine prepare an outline of a report and a discussion of how to define categories of status for the other members to review.  The outline would include specific questions for members to reply to and allow continued development of a document to be discussed by the working group at the 2008 Annual MeetingThis proposal was supported by all members of the working group.

Other business presented by members included: 1) A presentation from the State of Alaska on their forecasted catches in 2008.  The forecast is for the 18th largest catch since 1960 and 2) the Secretariat identifying that with the reported 2007 preliminary catches provided by Russia, the total catch of Pacific salmon in 2007 exceeded one million metric tons and was the largest historical catch of Pacific salmon.

 

(c)    Working Group on Salmon Marking (WGSM)
 
 

The Working Group discussed the status of the NPAFC Otolith Mark Database, marking plans for brood year 2008 salmon, and the success of designating thermal mark patterns for specific countries.

The chair presented a summary of hatchery releases of salmon for the last 14 years as well as a summary of the growth of otolith marking.  The presentation also showed graphs depicting the portions of releases that have or do not have associated images in the database.

At this time, only Japan and Korea have all year 2007 releases in the databaseUnited States has not submitted release information for States of Washington and Oregon for 2006 or 2007; Russian release data are not available for 2006 or 2007 releases; and release data from Canada for the years 2004 through 2007 have not been submitted.  Images of otolith marks are also missing for all releases from the States of Washington and Oregon and recent years releases from Russia and Canada.

Country Reports:

  • Canada expects to update release records soon.

  • Japan reported that there may be some changes in their release plans.

  • Korea reported that they had a single release in 2008 that represented about half of the production at Yangyang.

  • United States reported that they had submitted three reports summarizing releases by release year for the years 2005, 2006, and 2007 (Alaska) and presented a summary of otolith marking in seven states ranging from Washington and Oregon to MinnesotaOnly Washington, Oregon and California currently have anadromous releases of salmon.

  • Russia reported their release plans by species for 2008 brood yearThey are using thermal marking at seven hatcheries and dry marking at ten hatcheries; almost all groups are marked as eggs however in one instance they will be marking after the hatch.

The Secretariat presented a summary of ocean recoveries of otolith marked chum salmon in the Gulf of Alaska during the winter of 2006 as well as results of stock identification by DNA analysis.

 

(d)    Ad Hoc Working Group on Stock Identification (WGSI)
 

The goals of the Working Group are to: 1) develop, standardize, and disseminate genetic and other databases among the Parties; 2) encourage the development of new genetic technologies; and 3) facilitate the dissemination of statistical techniques.

Most Working Group business has been resolved by correspondence.  Tissue requests have been largely met, and much progress has been made on Pacific Rim data bases for SNPs.  The United States and Japan made extensive progress on the SNP baseline for chum salmon but it is not reported.

Canada, Japan and Korea expressed interest in a pink salmon collaboration, but all Parties had concerns about funding and resources at this time Canada offered the use of its existing microsatellite database, and the Parties were urged to explore this option.

The United States described their project to develop a SNP database for steelhead.  They have access to 30 SNP assays at this time and anticipate many more in the near future.

The Parties have provided many samples to ADFG for SNP analysis.  J. Seeb (U.S.A.) will consolidate these collections at the University of Washington laboratory for SNP analysis.

 

 
(e)    BASIS Working Group (BASIS WG)
 

The BASIS Working Group discussed several items including:

i) 2008 BASIS Symposium
 
The Secretariat provided a presentation to facilitate discussion on the working plan, adoption of the tentative program, and publication of the proceedings.

In addition, the proposal for the publication of the proceedings listed in Appendix 3 was adopted, however there was some discussion regarding the length of manuscripts accepted for publication.  The proposal limits the length of papers to 10 pages, including text, figures, and tables and some members believe that this may negatively impact the scope of papers submitted to the symposium With regard to this length limit, the working group decided to agree to the 10 page limit per paper as a guideline Papers that exceed this limit will not be excluded from the Bulletin, but if the total page limit for the Bulletin is exceeded, the group will re-visit this issue during the 2009 RPCM and at the 2009 Annual Meeting.

 

ii) Summary of BASIS 2002 to 2006
 
The working group agreed to include a review for BASIS Phase I as an introduction to the Proceedings for the BASIS Symposium, NPAFC Bulletin No. 5.  It was suggested the document include the reason why the BASIS program was initiated as reported in the Phase I research plan, a brief summary of the oceanographic conditions during the Phase I research, summary information on carrying capacity for salmon provided by Japan, Russia, and the United States Other pertinent information gathered during the BASIS Symposium may also be included as a summary in the report.  A brief discussion on what was learned during BASIS Phase I, in relation to long-term monitoring for Pacific salmon will also be included.  E. Farley (U.S.A.) will work on this document with the help of BASIS Working Group members from other Parties.  The review document for BASIS Phase I will be submitted for peer review for publication in Bulletin No. 5.

 

iii) Development of Plan for BASIS Phase II
 
At the 2007 CSRS meeting, the Chairman recommended that Parties revisit the draft BASIS Phase II plan and contribute to editing the draft document and to provide these suggestions/edits prior to the 2008 RPCM.  No edits or suggestions were received prior to the 2008 RPCM; thus the chairman suggested adopting the draft plan and the working group agreed.

 

iv) Other Items
 
Members of the working group agreed to the suggestion by the CSRS Chairman, to create a web-based brochure on the NPAFC web site that would summarize pertinent results on salmon research provided at the BASIS Symposium.  E. Farley (U.S.A.) will work with the Secretariat and BASIS Working Group members on developing this brochure after completion of the BASIS Symposium in November, 2008.

 

(f)    Working Group on Salmon Tagging (WGST)
 
 
The Salmon Tagging Working Group had discussed by email communication on the terms of reference, NPAFC disc tag and poster, tag recovery procedures, tagging database, and other items.  The terms of reference agreed by the WG are: 1) manage the high-seas tagging database including the current INPFC/NPAFC tagging data and the future tagging activities, 2) coordinate the high-seas tagging experiments, 3) collect the release and recovery information and distribute them among the Parties, 4) report the annual summary of the high-seas tagging activity to the CSRS, 5) format disc tags with NPAFC logo for its future use, and 6) encourage reporting tag recoveries from the public.  Parties plan three tagging experiments in 2008; 1) Japan: 1,000 tags during the Wakatake maru cruise in JuneJuly, 2) US: 200 tags during the Oscar Dyson cruise in September, and 3) Russia: 500 tags during the TINRO cruise in June-fall.  The new NPAFC-logo tags will be used in these experiments and paper posters will be distributed to contact persons of Parties.  The number of posters requested by the Parties has been increased to 1,000 in total (Canada: 250, Japan: 300, Korea: 50, Russia: 100, and USA: 300).  The Secretariat will make efforts to accommodate these requests of increases from the original planElectronic version of the poster will also be made available.  Tag recovery procedures, the format of tagging database, rewards for tag recovery reports, and future cooperative tagging programs were also discussed.
