Hard clam populations in areas only 9 miles apart had persistent differences 

 in fatty acid composition which did not change after 3 1/2 months of 

 transplantation to a common environment. It was concluded that the 

 difference was genetic, although induction by specific environment was also 

 recognized. - J.L.M.

After 3 1/2 months in Narragansett Bay Mevaenavia mevaenavia from Pt. Judith 

 Pond differed in fatty acid composition from clams native to Narragansett 

 Bay. Pt. Judith clams had higher relative concentrations of 14:0 and 16:1 

 but less 18:0 than those from the Bay. A small, but distinctive qualitative 

 difference also was noted on chromatograms between 20:1 and 18:4 peaks. 

 Another difference was prevalence of short-chain acids (less than C12) in 

 Pt. Judith clams. In a short experiment the next summer, clams from a 

 polluted area in upper Pt. Judith Pond had exceptionally low concentrations 

 of 16:0 between 14.6% and 19.4%, but this appeared to be a peculiarity of 

 the year. Experiments were to be repeated over a longer period. - J.L.M.

Free amino acids can be used to show abnormality resulting from pollution. 

 The ratio of taurine to glycine, for example, is at least twice as high in 

 Mevaenavia mevaenavia subjected to hydrocarbon wastes as it is in clams 

 from clean estuarine waters. This appears to be a permanent "biochemical 

 tag" that is not lost when clams are transplanted. - J.L.M.
