Oyster aquaculture production in Virginia has increased tenfold in the past four years due, for the most part, to the development and dissemination of disease-tolerant oyster stocks. Anu Frank-Lawale of VIMS is examining whether larval growth traits and survival can be improved without compromising important traits in adult oysters, such as disease tolerance, growth rate, and meat weight. This research could provide new breeding strategies for hatcheries, ultimately improving the performance of stocks.
