Detailed evaluation of 10 species as potential subjects for aquaculture in 

 New England, according to 9 criteria, rated Mevcenavia mevcenavia 6 on a 

 scale from to 9 , with 9 as highest possible score. Negative characteristics 

 were growth rate, conversion efficiency, and availability of commercial feeds.

Uptake and retention of Rhodamine B by quahog clams, Mevcenavia mevcenavia. 

 Chesapeake Sci. 5(3): 134-137. 



Concern had been raised that dye used to trace water movements in the natural 

 environment might stain clams and so affect their market value. Laboratory 

 experiments with Mevcenavia mevcenavia showed that at high concentrations of 

 dye (60 to 250 mg/liter) clams avoided dye by withdrawing siphons and closing 

 valves. At 8.4 mg/1 there was some avoidance reaction, but siphons remained 

 exposed, reacting with sporadic openings and closings of the apertures. At 

 4.7 mg/1 and less, clams appeared to siphon normally. Between 4.7 and 0.45 

 mg/1 gills and body tissues stained in 15 min. At 0.25 mg/1 clams became 

 pink in 30 min. At 0.09 mg/1 clams held up to 48 hrs did not stain. At 

 0.045 mg/1 and less no color was taken up in 120 hrs. Outer surfaces of clam 

 shells were stained at 0.96 mg/1 and above. Below 0.45 mg/1 inclusive, shells 

 did not stain. It was concluded that relatively few clams would be stained 

 by concentrations of Rhodamine B commonly used in tracer studies. If 

 staining did occur, the results showed that siphoning action and metabolic 

 breakdown of dye would clear the flesh in a few days. - J.L.M. and M.W.S.

Transplant program means dollars for hard-pressed N.J. clammers. Natl. 

 Fisherman 58(8), Dec. 1977: 2-B. 



The N.J. Dept. of Environmental Protection began transplants of hard clams, 

 Mevcenavia mevcenavia , from polluted to clean waters, 8 yrs ago when clams 

 were transplanted from Lakes Bay in Atlantic County to Great Bay. In 1977 

 the program was expanded when clams were moved from Tuckerton Creek in 

 Ocean County to Great Bay. Clammers had been unable to make a living from 

 depleted beds in the few remaining clean waters of the State. In 5 days 

 8 9 men took 1.5 million clams, mostly littlenecks and cherrystones. Summer 

 clamming continued poor, however, and a special appeal was made to the 

 Governor's office. In September a transplant from Manasquan River to 

 Barnegat and Great Bays began. In 10 days 76 men harvested and transplanted 

 1,216,500 hard clams under State supervision. The Manasquan had not been 

 used for clamming in 17 yrs. The following week clams were transplanted 

 from Shark River. Clammers paid $25 each for permits and $42 to lease 1/2- 

 acre individually marked lots where each man replanted his own clams. If
