Improving Pacific Oyster Broodstocks

Report of April 1997 to March 1998

Document format: pdf

Publisher: Western Regional Aquaculture Center

Creation date: March 31, 1998

The project had the following objectives in year 1: (1) to test the performance of hybrids produced by controlled crosses of existing WRAC inbred lines, at a commercial scale, in different environments, and in comparison both to existing commercial stocks and to select families in the Molluscan Broodstock Program (MBP, Hatfield Marine Science Center, Newport, Oregon); (2) to create triploids from combinations of two and three inbred lines and test their early hatchery and nursery performance; (3) to measure the metabolic performance of inbred and hybrid larvae at whole organism, cellular, and subcellular levels to determine the metabolic basis of hybrid vigor and to enable subsequent correlation of larval metabolism with growth to market size. Owing to a delay in the MBP spawning schedule, a fourth year 1 objective, to make new inbred lines from the pedigreed families being produced by the MBP, was postponed until year 2. Oregon State University (OSU) was an unfunded participant in year 1.
