Culture Technology to Support Restoration of Herring in PWS Quarterly Tasks

2008 Quarterly Project Tasks:

1st Quarter Tasks (October 1, 2007 - December 31, 2007)
Status: Complete

Tasks to be performed:

Coordinate with the Japanese researchers for attendance at the AKMSS.

Progress report:

The PI has contacted Dr. Matsubara to inquire regarding travel to Alaska to participate in herring discussions. Dr. Matsubara has indicated that he would be available, but not until after February. Subsequent inquiries to establish specific travel dates have not been answered. The most recent request for information was sent January 4. Problems, issues or delays: Recent attempts to contact Dr. Matsubara have been unsuccessful. End of year activities at the Japan Fishery Research Agency may be constraining his ability to respond.

2nd Quarter Tasks (January 1, 2008 - March 31, 2008)
Status: Complete

Tasks to be performed:

Plan and coordinate travel for Dr. Takahiro Matsubara and an associate or designee to travel to Alaska to attend the Marine Science Symposium in January 2008, participate in an EVOS Trustee Council sponsored workshop on herring stock restoration, visit the fish culture facilities at the ASLC, the Seward Shellfish Hatchery and USGS Marrowstone Field Lab (Nordland, WA), tour potential stock restoration rearing and release sites in PWS (e.g. Tatitlik), and meet with scientists and interested parties involved in the Prince William Sound herring restoration effort.

Progress report:

March Obj 1: Communications continue with Dr. Takahiro Matsubara. Travel for Dr. Matsubara and his collegue, Dr. Ohkohchi, is tentative for May 7-16. At this time, scheduled in collaboration with EVOS Trustee Council Executive Director, Michael Baffrey, all travel party members including grantees, EVOS TC staff and Executive Director, as well as Dr. Matsubara are tentatively scheduled to tour Dr. Paul Hershberger’s herring disease lab at the USGS Marrowstone Field Lab in Washington state on May 12. This will be following by travel to Seward for tours of the ASLC and the Alutiig Shellfish Hatchery on May 14, including travel to Tatitlek to inspect the shellfish facility at that location. May 15 will be reserved for a stakeholder/scientist workshop in Cordova, with final departure from Anchorage on May 16. PI and co-PI are in communication with EVOS TC Executive Director Michael Baffrey to finalizing trip plans. March Obj 2: Plans are finalizing for travel to PWS to collect herring. Travel will be timed to coincide with the PWS herring spawn. We will sample herring eggs, measure and characterize herring yolk proteins, amino acids and bound calcium in the blood and developing eggs. We will look for changes in these factors comparing healthy and stressed fish. We are communicating with Dr. Matsubara on details for developing a vitellogenin assay for this task. Charter vessel is standing by for herring collection.

3rd Quarter Tasks (April 1, 2008 - June 30, 2008)
Status: Complete

Tasks to be performed:

Conduct an assessment (survey) of yolk proteins and products in female herring that affect gamete quality and potential larval recruitment during the spawning cycle in PWS.

Progress report:

Objective 1: Dr. Takahiro Matusubara and Mr. Hiroyuki Okouchi of the Fisheries Research Agency of Japan traveled to Seattle. Joining the Japanese scientists were Dr. Tim Linley (MariCal-ASLC)and EVOS TC staff including Exec. Director Michael Baffrey, Restoration Specialist Catherine Boerner and Dr. Doug Hay. Tours and meetings were held at the Marrowstone Field Research Station with Dr. Paul Hershberger, Jake Gregg and other station personnel. A second tour and meeting was held at the USGS Western Fisheries Center where Dr. Matsubara and mr. Okouchui presented on their work related to herring stock enhancement and reproductive endocrinology in marine fish. Additionally, the participants traveled to Alaska where Dr. Matsubara and Mr. Okouchi gave seminars on herring culture at the Alaska SeaLife Center. EVOS TC Restoration Specialist, Drs. Linley and Matsubara and Mr. Okouchi also flew to Tatitlek to tour and assess the Tatitlek Shellfish Hatchery as a possible facility to conduct herring culture in PWS. It was not possible to schedule travel for Dr.Matsubara and Mr. Okouchi to attend the Herring Restoration Workshop held in Cordova. Objective 2: Two trips to PWS were made to collect herring eggs. Only the first trip was successful for sample collection. Spawning herring observed by ADF&G that led tot he second collection trip had moved to deep water by the time sampling crew arrived in the area (Half Moon and Simpson Bays). The third trip was postponed due to inclement weather and finally canceled when ADF&G aerial surveys showed few spawning aggregations of herring left in PWS (early May). Collection trips were originally planned to synchronize with early, mid-cycle and late spawning herring. Samples were collected to measure and characterize herring yolk proteins, amino acids and bound calcium in the blood and developing eggs, while comparing these factors in healthy and stressed fish. Dr. Matsubara was able to provide a vitellogenin assay for this test.

4th Quarter Tasks (July 1, 2008 - September 30, 2008)
Status: Complete

Tasks to be performed:

Continue yolk protein analysis and prepare final report.

Progress report:

July-Sept Obj 2: During the 3rd quarter, herring samples were collected to measure and characterize herring yolk proteins, amino acids and bound calcium in the blood and developing eggs, while comparing these factors in healthy and stressed fish. 4th quarter activities included use of vitellogenin assay agents sent by Dr. Matsubara to run the assays to characterize herring yolk quality. Initial assays were conducted on standards provided by Dr. Matusbara to confirm efficacy of the antisera. Analysis of herring blood samples will be performed in January 2009. Problems, issues or delays: Initial assays were performed on known standards to confirm assay results provided through screening by Dr. Matsubara, which he suspected to be of questionable quality. Results performed in our lab indicated this was not the case
