would help. A significant problem concerns the authority and image of town 

 enforcers. They enforce the same laws as others and should be given the same 

 authority. Substantial poaching of undersized and clams from uncertified 

 areas continues. The best way to reduce poaching is by physical presence as 

 a deterrent. Forfeiture of gear and equipment should be mandatory for poaching. 

 Federal and state laws should be improved to prohibit traffic in undersized 

 clams. License revenues, fees, and fines should revert into funds for 

 enforcement, management, and research. - J.L.M.

Meraenaria (Venus) meraenaria is not mentioned. Reserpine and LSD affect 

 postural behavior of all species studied. Reserpine lowered the level of 

 5-hydroxytryptamine (5-HT, enteramine, serotonin) in central ganglia, and 

 induced tonic contraction of the muscular meshwork of the haemoskeleton and 

 abolished tonus of shell muscles. LSD had no evident effect on shell 

 muscle and had the opposite effect to reserpine on haemoskeletal muscles.

Total annual production of clam meats in the U.S. is 110 to 115 million 

 pounds, valued at $40 million to $42 million. Fifty percent of the value 

 ($20 million) were hard clams. Data suggest that total dollar market for 

 hard clams is as big or bigger than the market for oysters. The price of 

 hard clams has gone up half again as fast as oysters, doubling over the 

 past decade. Clams are increasing in popularity and have entered fast 

 food chains, suggesting that market size and unit price will continue to 

 rise. Hatchery operation and prototype production operations appear less 

 capital and labor intensive. Clams are hardier and can be fast growing. 

 Relative profitability of clams vs oysters should be scrutinized. - J.L.M.
