No title. Abstract in National Fisherman, June 1975: 3-B. 



Increased yields and easier harvesting are claimed for a new method developed 

 at the New York Ocean Science Laboratory. Seed clams are enclosed in contin- 

 uous bags of "Vexar" plastic netting made by DuPont Co. Mollusks are fed 

 through a metal tube sleeved with the flexible netting. Mesh size is about 

 1/2 -inch square. As the predetermined quantity of seed clams is fed they 

 bag themselves by pulling the required amount of netting off the outside of 



the tube. - J.L.M.

Growing your own clams and oysters. Univ. N. C. Sea Grant Program Newsletter, 

 July 1976 : 1, 5. 



Advisory agents are reluctant to advise people to plunge into oyster and 

 clam farming, since economic feasibility is still being tested. Clams like 

 shallow water with relatively high salinity, strong tidal currents, and 

 plenty of food. It must be in an area that can be observed and protected 

 from vandals. A pen must be built to keep out predators. Seed clams are 

 then put in the pen, then it is a matter of watching for holes in the wire, 

 removing crabs, raking off seaweed, and waiting 16 to 18 months for the 

 clams to grow to market size. The major question for viable culture is to 

 have enough survival to pay for pens and the lease, plus enough for a rea- 

 sonable profit. Clam rearing appears feasible provided the area is good for 

 growth. - J.L.M.

Bringing clams to the backyard in Buxton. Univ. N. C. Sea Grant Program 

 Newsletter, July 1976: 2. 



Describes a project to raise clams (Meraenaria meraenaria) . A pen was built 

 of treated wood pilings and vinyl coated wire. It was divided into 7 sec- 

 tions. Clams of various sizes were placed in each, 1/8 inch, 1/4 inch, 

 3/8 inch, and 5/8 inch. A lease for 5 acres has also been applied for. No 

 results are given. - J.L.M.

Clam pearls are a rare but delightful find. Marine Resource Bull. 9(1), 

 Va. Inst. Mar. Sci., Sea Grant Adv. Serv.: 3. 



Meraenaria meraenaria infrequently produces a pearl which is slightly softer 

 than the oyster pearl, but more varied in size, shape, and color. Such 

 pearls sell for about $35, usually to be set in jewelry. Some clam dealers 

 are said to hoard the pearls and shuckers have been known to hide them in 

 their mouths when they find them at work. Hard clam pearls are 1/4 inch or 

 smaller. They may be round or oval, but usually are slightly flattened 

 balls. Color ranges from white or rose to deep purple. Cooking destroys 

 gem quality. A pearl is formed when a parasite or other foreign substance 

 enters the mollusk. The clam tries to isolate the material with its shell- 

 forming substance. Not enough clam pearls are found to support a commercial 

 industry. - J.L.M.
