Actomyosin and regulation in molluscan muscles. Biophys. Soc, Progr. and 

 Abstr., 15th. Ann. Meeting: 234a (Abstract ThAM-CIO). 



Ca-dependent regulatory functions in molluscan muscles are associated with 

 myosin. Purified myosin preparations of Mercenaria mercenaria and 

 Aequipecten irradians bind Ca at free Ca concentrations of 10 - 7 to 10"^ M, 

 and their ATPase activity when mixed with purified actin is Ca-dependent. 

 Tropomyosin is not required for regulation by Ca in molluscan muscles. SDS 

 acrylamide electrophoresis of native thin filament preparations showed 

 essentially 2 components, actin and tropomyosin. Components with chain 

 weight smaller than tropomyosin were not found in native thin filaments. 

 Myosins from muscles of Mercenaria doublet with a chain weight somewhat below 

 20,000. The only component found in significant quantity in washed whole 

 muscle with a chain weight lower than that of tropomyosin was the light chain 

 of myosin. - J.L.M.

Overview of New York's shellfish resources. In Proceedings of a Workshop 

 on the Shellfish Management Program in New York State. N.Y.S. Dept. Envir. 

 Conserv. and N.Y. Sea Grant Inst., Albany: 7-9. 



The Indian name for Long Island was "Sewanhaka" - Island of Shells. Commercial 

 landings of Mercenaria mercenaria in New York for 1973 and 1974 were 607,286 bu 

 with landed value of $11,175,115 and 669,452 bu with landed value $13,434,190 

 respectively. These are minimal values because they do not include economic 

 values in the supply, processing, shipping, and retailing segments, nor do they 

 include recreational and "mess digging" values. Of nearly 3 million 

 New Yorkers who participated in recreational saltwater fishing in 1973-74 

 about 1 in 4 were recreational shellf ishermen. Shellfishes also are valuable 

 foods for other marine animals. Much of the fish and wildlife management effort 

 of the Department is devoted to acquisition of key wetlands with funds provided 

 by the Environmental Bond Act of 1972. The Department also works closely with 

 county, town and village governments and the Nature Conservancy in wetland 

 protection. Under provisions of the Tidal Wetlands Act of 1973 a major effort 

 goes to monitoring water quality to determine from which waters shellfish may 

 be taken safely. Considerable effort also goes into reviewing and evaluating 

 potential impacts of sewer projects, power plants, bridges, roads, marinas, 

 airports, and housing on the marine environment. The shellfish resource is the 

 foundation of an industry probably worth $100 million or more to New York.

Shellfish for the dinner table. In Proceedings of a Workshop on the

Shellfishes like hard clam and oyster are often eaten rav;, but they also are 

 delicious in many recipes. Cookbooks have been written on shellfish alone, 

 including one with 300 recipes written by 2 Long Islanders. Some people have 

 allergic reactions to shellfish, but to many they are important parts of the 

 diet. - J.L.M.
