Comparative growth of hard shell clams {Mercenaria mercenaria Linne and 

 Mercenaria campechiensis Gmelin) and their Fl cross in temperate, sub- 

 tropical, and tropical natural waters and in a tropical artificial upwelling 

 mariculture system. World Maricult. Soc, Proc. 7th. Ann. Workshop: 171-183. 



Growth of quahogs (Mercenaria mercenaria and M. campechiensis ) and their Fi 

 cross in a controlled experimental environment was compared to growth in 

 uncontrolled natural environments. Clams were spawned by Paul Chanley of 

 Greenport, N.Y. The controlled environment at St. Croix, U.S. Virgin Islands 

 had no pollutants or predators and fouling was minimal. Salinity was 34.75 

 to 34.95°/°° and water temp 22 to 30°. Clams from each of the 3 populations 

 were planted at Southold, N.Y. and at both St. Croix sites. M. campechiensis 

 and Fi clams were sent to Wachapreague, Virginia and Alligator Harbor, Fla. 

 and M. mercenaria and Fi to Hawaii. M. campechiensis and Fi clams reached 

 market size in 6.5 to 13 months in the St. Croix artificial site. Clams did 

 not reach market size by 13 months in Southold, Wachapreague, or Salt River 

 Inlet, St. Croix. Fl clams in Hawaii, and Florida were close to market size 

 when the experiment was terminated after 13 months. Survival and growth of 

 M. mercenaria was poor in the artificial upwelling area, in Salt River Inlet, 

 and in Hawaii. - modified authors' abstract - J.L.M.

A population census of hard clam (Mercenaria mercenaria) in Greenwich Bay, R.I, 

 late in 1954 showed the lowest density in 5 yrs of sampling. The decline in 

 abundance was accompanied by a drop in average number of boats clamming. -

In 1908 the Bureau of Marine Fisheries of New York State said that no oysters 

 were being harvested from the New York Bay area, although in 1908 and 1909 

 oysters were being taken from the vicinity of Robbins Reef, Kill Van Kull, 

 and the Rahway River. Value of shellfish produced in Harbor waters in 1908 

 amounted to $1.3 million and it was thought that the waters in Lower Bay 

 could be maintained for shellfish culture. In 1925 Lower New York Bay was 

 closed to shellfishing by authorities. N.J. opened Raritan Bay beds in 1934 

 because treatment facilities were impro\ r ed. A portion of New York's beds 

 were reopened in 1941. The value of the- industry at that time was about 

 51.0 million. In 1961 after a hepatitis outbreak the Bay was once again 

 closed to shellfishing. Subsequently, N.J. reopened the Sandy Hook beds.
