The only material in this paper pertinent to Meraenaria meraenaria is that 

 the protein preparation was prepared from whole adductor muscles of hard 

 clam. The extraction procedure was described in a paper by Johnson et al. 

 (1959) abstracted elsewhere in this bibliography. - J.L.M.

Meraenaria meraenaria, bay quahaug , is the most abundant animal of its size 

 living in the bottom of Narragansett Bay. Habitat, spawning, growth, and 

 distribution in Rhode Island waters are described by reference to published 

 papers abstracted elsewhere in this bibliography. It is stated that the 

 stocks in Narragansett Bay could sustain a much larger harvest. Quahaugs in 

 dense, underharvested beds may be buried several layers deep in sediments, 

 and only a fraction of those present will be taken with a single pass of a 

 dredge. It is assumed that productive areas can produce a sustainable annual 

 yield of about 25% of the standing crop. The most productive beds in the 

 Providence River are polluted, and closed to harvesting. Reported commercial 

 landings rose irregularly to a peak of about 5 million pounds of meats in 

 1955, then declined rapidly. Landings have been below one million pounds 

 since 1972, and it was predicted that the decline would continue if no action 

 were taken. - J.L.M.

The accumulation of dopamine-^H by Meraenaria ganglia. Am. Zool. 10(4): 

 503-504 (abstract) . 



Ganglia of quahog contain high concentrations of dopamine which can be 

 synthesized locally from exogenous DOPA. Isolated pedal ganglia incubated 

 in 0.1 uM dopamine- 3 H solutions (S.A. 10.6 mC/u mole, 10 min, 21.5°C) 

 accumulated a dopamine concentration 2.4 times higher than the external 

 medium. (Abstracter's note: authors commonly confuse the terms higher and 

 as high; 2.4 times higher means 3.4 times as high. The basic data are not 

 given, so it was not possible to determine whether the statement as given 

 is correct) Ganglia concentrated dopamine-^H at levels higher than those 

 in ganglionic extracellular spaces, but other tissues (digestive gland,
