the east. The Southampton Water stock appears to be physiologically adapted 

 to spawning at lower temperatures than in the U.S. (18 to 20°C) . It is 

 suggested that greatest recruitment occurs when summer river flows are low, 

 which reduces flushing of larvae down the estuary and produces optimal 

 temperatures and salinity. Recent reclamation work in the area, and increased 

 commercial harvesting, probably will alter the distribution, density, and 

 population structure. The major commercial fishery began in 1965. The 1971 

 catch was about 100 tonnes (over a million clams greater than 50 mm long) . -

The crystalline style of Lamellibranchia. Quart. J. Micro. Sci. 44: 591-602. 



This is a general discussion of the nature and functions of the crystalline 

 style. At the time it apparently had not been observed in Venus but the 

 author predicts that it will be shown to be present in all lamellibranchs. 

 He concludes that it is an active amylolytic ferment; stored up as a 

 flexible solid in the caecum or in a compartment of the alimentary canal; 

 the end that projects into the stomach is dissolved slowly there and mixed 

 with particles of food material, the starchy portion of which is transformed 

 by it into a reducible sugar. The paper is illustrated with drawings. - J.L.M.

Paramyosin from adductor muscles of V. mercenaria was homogeneous in ionic 

 strength 0.6 at pH 7.2 and above, and S20 was 3.1 S. Molecular weights 

 determined by the Archibald method and light-scattering were 206,000 and 

 190,000 respectively. Axial ratio was 71, using Simha's factor, and length 

 determined by light-scattering was 1400A. - J.L.M.

A method for cultivating molluscs. Aquaculture 5: 215-218. 



In 1965, Long Island, N.Y., the most important hard clam (Mercenaria 

 mercenaria) producing area in the world, had closed 22.3% of its total 

 shellfish acreage in Nassau County because of pollution. By 1 Jan 1974 

 about 62% of the total shellfish areas in Nassau County were closed. By 

 enclosing mollusks in the interior of a tube of netting material, and 

 floating from a raft, or buried in a suitable benthic sediment, clams can 

 be harvested, retained in the netting for depuration, and shipped directly 

 to market. - J.L.M.
