Diploid and Triploid Oyster Performance in Maine

Tom Kiffney University of Maine

Two sets of chromosomes or three? Diploid oysters, the genetic variant most commonly found in the wild, have two sets of chromosomes- one from each parent. Triploid oysters, meanwhile, contain three sets of genetic material making them sterile, faster growing, and larger than their diploid counterparts. In this webinar, Tom will discuss his research on diploid and triploid oysters in the Damariscotta River. In his investigations, he compares different growing environments, culture systems, and oyster physiology to improve understanding of oyster cultivation in Maine's most productive oyster farming region.
