Muscle arylamidase activity of several marine species. J. Fish. Res. Bd. 

 Canada 31 (4) : 445-449. 



Arylamidases are enzymes that can hydrolyze amino acid-B-naphthylamides . 

 They are inhibited by puromyocin and can be differentiated from other 

 exopeptidases by this property. This study was part of a larger study of 

 enzymes involved in proteolytic breakdown of muscles of marine animals. 

 Quahog clam (presumably Mercenaria meroenaria, although scientific names 

 were not given) was among the 3 fishes and 3 invertebrates examined. 

 Optimum pH for activity was between 7.0 and 7.5, using alanyl-3-napthylamide 

 as substrate. Maximum activity of the clam was shown with leucyl-6- 

 naphthylamide. Puromycin inhibited the arylamidase. Apparently only one 

 arylamidase was present in clam muscle. - J.L.M.

R.I. shellf ishermen organize, gain new allies in battle to save Narragansett 

 Bay clamming. Natl. Fisherman 59(2): 20. 



By banding together and forming a Shellf ishermens Association local operators 

 have been able to put political pressure on local and state elected officials 

 and kill a proposed bill that would allow building of depuration plants to 

 clean polluted clams. The shellf ishermen argued that such plants would 

 remove the incentive to clean up the bay. The fishermen also believed that 

 pressure should be put on the City of Providence to modernize the sewage 

 system so that the upper Bay would not have to be closed down every time it 

 rains more than an inch. Even the old-time hand rakers are seeing the value 

 of joining together. - J.L.M.

An annotated bibliography of oysters with pertinent material on mussels and 

 other shellfish and an appendix on pollution. Texas A. and M. Research 

 Found., College Station, Tex., 794 p. 



Abstracts are listed in alphabetical order by author. Some are extensively 

 summarized. Usefulness of the bibliography is enhanced by a rather detailed 

 subject and author index. References to Meroenaria (Venus) meroenaria are 

 abstracted elsewhere in this bibliography. - J.L.M.

Reproduction in bivalve molluscs under environmental stress. In Physio- 

 logical Ecology of Estuarine Organisms. F. John Vernberg (edi . Univ. S.C. 

 Press, Columbia, S.C, 259-277. 



This is essentially a review paper, although some original data are included. 

 Some data are from unpublished work of others. It is not clear from the 

 context whether any new data of the author are included. Ambient temp and 

 food levels synchronize different stages in bivalve gametogenic cycles. 

 Changes in either variable have limits, beyond which gametogenesis fails or 

 does not occur. Within these limits, animals show considerable tolerance, 

 even under conditions of stress at which they have to utilize their own 

 tissue reserves to meet basal energy requirements. Under such stresses 

 fecundity is reduced and vitality of gametes and vigor of larvae are impaired. 

 This may be at least partially caused by reduced synthesis of neutral lipid 

 in developing ova. References to Meroenaria mercenaria are limited to 

 citations of work of other authors, abstracted elsewhere in this bibliography.
