The relationship between stock and recruitment in exploited invertebrates. 

 In Fish Stocks and Recruitment. B. B. Parrish (ed.) Cons. Internatl. 

 Expl. Mer, Rapp. Proc.-Verb. 164: 113-131. 



The author quotes John Glude (pers comm) who knew of no instance where 

 extremely high abundance of spawners of Meroenaria has in itself led to low 

 recruitment, nor where low recruitment could be attributed to insufficient 

 spawners. Most of the paper deals with stock-recruitment relationship in 

 cockle (Cardium edule) which, for lack of better information on hard clam, 

 might be used to infer relationships, or to plan research on hard clam 

 stocks. - J.L.M.

New methods were used, which depend upon deposition of small amounts of cupric 

 ferrocyanide (Hatchett's Brown) at sites of enzyme activity. In mantle edge 

 of Meroenaria meroenaria enzyme activity was mainly associated with the outer 

 mitochondrial membrane, but extramitochondrial deposits were associated 

 occasionally with the plasma membrane of mucocytes . - J.L.M.

 nail predation than Venus (Mevcenaria) 

 but the conclusions probably are generally 

 of clam consumption decreased as water temp 

 lowered. P. duplieata did not feed at water 

 P. heros fed at water temps down to 2°C but

Effect of metallic aluminum particles on oysters and clams. 

 6(3): 146-149. 



Chesapeake Sci. 



Experiments were done on Crass'ostrea virginica and Mya arenaria, Meroenaria 

 meroenaria is not mentioned. Fine particles of metallic aluminum are used as 

 targets in photogrammetry . They could be hazardous to marine life. The 

 experimental mollusks removed aluminum particles from the water by filtering, 

 but no increase of aluminum was detected in bivalve tissues or in water 

 samples. These bivalves apparently react to aluminum particles as they would 

 to arty other inorganic material in the same size range. - J.L.M.
