Grow-Out And Marketability Evaluation Of Triploid Deby Oysters, Gustavo Calvo
Reports
Triploid DEBY clearly outperformed their diploid counterparts in terms of survival, growth and condition over the course of this study at the site of Sweet Amalia Oyster Farm in Mathews, VA. By November 2004, when oysters were approximately 28 month old, cumulative mortality was 11 % in triploids and 43% in diploids. At that time, 41 % of the triploids were of market size (3 inch) whereas none of the diploids had even attained 2.5 inch. Condition of triploids and diploids similarly increased in fall 2003 and remained high over the winter and spring 2004. However, while condition decreased slightly …

Development Of Grow Out Techniques Utilizing The Water Column In Growing A Non Native Oyster (Crassostrea Arikensis), Andy Drewer
Reports
This project addressed grow out techniques utilizing the water column in growing non native oysters (Crassostrea arikensis) in a containerized manner. The purpose of this project was to evaluate the cost effectiveness of growing, in commercial quantities for the processing segment of the industry, a non- native oyster in different types of stackable trays suspended in the upper water column by a raft.
