together in a boulder-protected area after one of the cages had 

 been pulled off the site. 



Tagged scallop release and recapture. 



The scallops were transported to Jeffreys Ledge (42°52, 

 70°08') onboard the R/V EDWIN LINK. The three cages were 

 attached to each other with polypropylene cord and then dropped 

 from the side of the vessel onto a flat sandy bottom. The 

 scallops were then dumped in and around the cages from plastic 

 buckets carried down by the submersible JOHNSON SEA-LINK I 

 (Harbor Branch Oceanographic Institution) on 14 July 1985. The 

 cage location was determined with LORAN C. In addition, a 37 khz 

 pinger surrounded by steel rods and encased in a cement block was 

 left next to the cages. This experimental site was revisited on 

 4 July 1986. 



The scallops were transported to Fippennies Ledge (42°45' 

 69°15') onboard the R/V ATLANTIC TWIN. The three cages were 

 dropped overboard individually in a large boulder field. 

 Scallops were looped by their spaghetti tags on a cord strung 

 along the inside of each cage. This ripcord was pulled on the 

 bottom by the manipulator arm of the submersible DELTA (MARFAB), 

 allowing the scallops to settle inside the cage on 6 July 1986. 

 The scallops on the outside of the cages were dumped from a cloth 

 bag carried down by the submersible. The relative position of 

 each of the cages was noted, and these sites were revisited on 

 26-28 June 1987. 



RESULTS 



Tagged scallop recapture 



The 1985 release site on Jeffreys Ledge had been disturbed 

 by extensive trawling in the area. Unfortunately, all that was 

 recovered were an overturned pinger in a cement block, 23 dead 

 tagged scallops (DEADE and DEADI ) , and one live tagged scallop 

 (LIVETAG). Even after a thorough search of the vicinity, the 

 three cages were not found. Trawl marks, occasional middens of 

 shucked scallops, and piles of rocks were further evidence of the 

 extensive trawling in the area. 



Conversely, two of the three 1986 release sites on 

 Fippennies Ledge were undisturbed. The one cage that had been 

 moved by trawlers was found, but there were no scallops collected 

 for that site. The scallops from the other two sites were 

 collected individually with the manipulator arm on the DELTA and 

 then placed in a cloth bag on the side of the submersible. These 

 results are summarized in Table 1.
