HNRY Oyster Eyed Larvae VA

Disease resistant and triploid oyster brood stocks produced under license with the College of William and Mary.  Breeding work by the Aquaculture Genetics and Breeding Technology Center (ABC) at Virginia Institute of Marine Science (VIMS).

To make the sterile, robust, fast growing triploid, male tetraploid lines are used, also created and improved at ABC, to cross with the female diploid line, which yields triploids.

The family selected lines are undergoing intense, directed selection by ABC, with continual improvements each generation. Family breeding provides a means of adding multiple traits, such as meat yield and cup shape to the principal ones of disease resistance and fast growth. HNRY high salinity oysters are tested in separate environments to provide a full range of performance across mid Atlantic conditions and similar environments.

• A medium to high salinity stock.
• MSX resistant 
• and Dermo tolerant.  
• The ancestors of this stock are a composite of early mass selected high salinity lines that are now bred using family breeding techniques.
• Selection traits include fast growth,
• high survival,
• shell shape,
• and high meat shell ratio.

Shellfish growers have the ability to select from a number of lines that have shown their utility for various growing conditions in the mid Atlantic and similar growing environments. Finding the right one for you is ultimately a function of your specific farm conditions and grow out techniques and therefore a matter of trial and error. If you are currently using a particular line, and want to try another, try a small quantity of the new line before jumping ship. Whichever line you settle on, most people use the triploid version of it.

Thses eyed larvae have a setting rate of 1.3% to 58% with an average of 17.4%.

First availability starts in March.
