Accomplishments

1. A key finding from several laboratories determining the genetic basis for heterosis and crossbreeding in Pacific Oysters is that superior hybrid performance relative to inbred performance relies on a combination of additive and dominance effects. 2. A PCR/RFLP identification key based on the ITS-1 and COI gene regions for Indo Pacific Crassostrea species is able to differentiate between ariakensis and other species. 3. Five new microsatellite markers have become useful in the preservation of genetic diversity in wild hard shell clams (Quahogs) and distinguishing them from cultured clams. 4. In Maine, a collaboration has emerged between the University and ten farms which helps to support the oyster breeding program for that region. 5. An effort is proceeding in Virginia to foster selective breeding in order to layer MSX resistance atop dermo resistance. 6. Several important outcomes of immune response in oysters have been delineated. Nitric oxide production is intimately involved in parasite control in oysters. Histone H4 is also involved in response to infection.

Impacts

  1. WERA-099 blends an excellent group of researchers, industry representatives and extension personnel in a discussion of the current problems facing the oyster industry. At the meeting there are intense discussions of breeding systems, culture techniques, nutrition and disease problems. Many collaborative projects have emerged as a result of these discussions.
  2. WERA-099 enhances international collaboration. Researchers from France, New Zealand and Australia regularly attend the meetings.
  3. WERA-099 promotes graduate education. Graduate students regularly attend these meetings, present their findings and interact with faculty from other universities. They access information that is applicable to their present and future studies. Occasionally, students are matched with post-doctoral fellowships as a result of interactions at the meeting.
