Effects of the treatment of an oyster bed with Polystream and Sevin. 

 Chesapeake Sci. 7(4): 179-188. 



Application of a Polystream-Sevin formulation did not control oyster drills 

 on a half-acre plot in Hog Island Bay, near Wachapreague, Va., and oyster 

 production was not increased. Most macroinvertebrates were affected 

 adversely. Mortalities of Mercenaria mercenaria were low, about 8% on the 

 treated area and 1% on the control plot. - J.L.M.

A review of the nature and extent of damage caused by oil pollution at sea. 

 Trans. 26th. N. Am. Wildl. Nat. Res. Conf.: 343-355. 



Mercenaria mercenaria supports an industry in R.I. which grosses over $2 

 million/yr for diggers. Quahogs seem to be virtually immune to oil pollution. 

 According to R.I. Dept. of Health, quahogs flourish in Narragansett Bay near 

 Providence where the Bay bottom is literally paved with oil. Meats, however, 

 have strong oily odor and taste. Thus, an oil spill could damage the 

 industry and affect consumer acceptance even if clams survived. - J.L.M.

Hazel, Joseph E.,and Thomas R. Waller. 1969. 



Stratigraphic data and length of the synodic month. Science 164(3876): 201- 

 202. (With commentary by Giorgio Pannella and Copeland MacClintock.) 



The paper criticises a paper by Pannella, MacClintock, and Thompson (1968) 

 (abstracted elsewhere in this bibliography) for errors in age assignments of 

 specimens, including Mercenaria campechiensis ochlockoneensis (Mansfield), 

 discrepancies in radiometric dates, and weaknesses in primary growth banding 

 data. Replotting the Pannella et al. data, the authors concluded that there 

 was no significant change in length of synodical month from Maestrichian to 

 late Paleocene, but a rapid decrease from late Paleocene to the present. In 

 their response, Pannella and MacClintock admitted to taxonomic error, 

 explained some of their procedures, but suggested that it was premature to 

 draw some of the conclusions made by their critics. - J.L.M.

 Program (Estuarine and coastal studies), Sea Grant Tech. Bull. 3, vi + 225 p. 



Venus mercenaria occurs from Maine to south Florida in most sheltered bays 

 along the entire coast. The commercial fishery in 1965 produced 11,383,000 

 pounds from New York to Florida. The hard clam industry is the most valu- 

 able commercial fishery in New York State . Charts are given showing general 

 areas of production in each State. - J.L.M.

Invertebrate survey of Flax Pond,- Summer - 1967. Mar. Sci. Research Ctr. ,

Of 14 environments examined, Mercenaria mercenaria was found in only three, 

 in muddy sand and mussel beds in Smith's Pond, Child Channel, and Flax Channel- 

 Gull Inlet. Hard clam apparently was not abundant in any area. - J.L.M.
