“I have been a proud grower of A.R.C. oysters for many years and can say they have some awesome brood stock!!”
High Survival Rates, High Growth Rates, Customer Satisfaction
For 40+ years A.R.C. has been concentrating on spawning, growing and nurturing high-quality shellfish seed for farmer/growers. Our lines of brood stock are mixed with carefully selected wild-caught specimens and we have created our own proprietary strain of algae to feed the juvenile shellfish. Three strategically placed nurseries allow the seed to grow to desired size in low density, healthy environments and help keep seed moving to meet our customers’ demand.
A.R.C.’s staff includes biologists, aquaculturalists, and experienced farmer/growers. We build most of our own custom equipment and are often experimenting with spawning and growing techniques to advance the field of aquaculture. Our expert staff is often consulted by industry professionals and would be happy to share their knowledge with you. For technical advice, please call 508-385-3933 x2.

A.R.C. unconditionally guarantees the viability of seed upon departure from our nursery. However, we accept no responsibility for growth and survival thereafter.
There will be an additional charge of 15% for orders of Triploid and DBY Oysters to cover royalty fees associated with licensing issued by patent owner, Virginia Institute of Marine Science.
Finding the Right size seed
Shellfish farmers have equipment and expertise geared to different sizes of seed from which they want to start growing. A.R.C. seed size is based on the highest mesh screen size on which the seed will sit. For example, R8 seed will sit on (be retained on) an 8mm screen without falling through.
A.R.C. Size of Size of
Sieve Size Seed (mm) Seed (in.)
R1.5 2.0 – 3.2 .079 - .126
R2 3.2 – 4.2 .126 - .157
R3 4.2 – 5.3 .157 - .209
R4 5.3 – 8.0 .209 - .315
R6 8.0 – 11.0 .315 - .433
R8 11.0 – 16.4 .433 - .646
R12 15.0 – 20.0 .591 - .787
R3/4 20.0 – 25.0 .787 - .984
3mm ≈ 1/8" 6.3mm ≈ 1/4"
13mm ≈ 1/2" 19mm = .75”
“R” stands for Retained on.
The number Indicates the approximate size (in millimeters) of the largest screen on which the seed can be retained. So, an R4 seed is “Retained On” a 4mm screen. It will, however, fall through a 6mm screen.
To avoid losing some seed through the mesh in your bags, when placing seed in mesh containers always use a mesh size at least one size smaller than the mesh the seed was Retained on.
Size ranges were developed using quahog seed. Oyster seed will be very close to the ranges indicated. Surf clam seed will generally be larger in length than the ranges indicated.
