- Assess the effects of seasonality on reproduction and condition index (CI) for Crassostrea gigas in Hawai`ian fishponds and other sites to determine ideal harvest and stocking schedules and maximum stocking densities.
- Improve triploid C. gigas performance by testing different triploid crosses. The triploid crosses will be produced by using lines developed by the Molluscan Broodstock Program (MBP) and the Midori C. gigas strain as the diploid parents to be crossed with tetraploid oysters. Crosses will be tested in Hawai`ian fishponds and other sites to determine whether these triploids differ in performance from previous triploids crosses.
- Develop a high-value half-shell oyster product for Hawai`i by conducting grow-out trials of a newly developed indigenous oyster species (Dendrostea sandvichensis) and Kumamoto oysters (C. sikamea).
- Test culture methods for Manila clams to improve survival and growth.
- Test a new broodstock conditioning system for Tellina palatum (Hawai`ian clams) to improve on previous spawning trials.
- Conduct outreach to transfer the technology developed in Objectives 1-5.
