Egg-bearing female lobsters and sub-legal size lobsters were tagged 

 and released because these two categories may not be commercially landed. 

 Two tagging methods were used . One type of tag was taped to the lobster 

 claw to be used to identify short-term movements of the lobster during the 

 period of the experiment . The second type of tag was the one normally 

 used by NMFS to obtain information on long-term migratory behavior and 

 population dynamics of the lobster stocks. The temporary tags were used 

 on the Delaware II, the standard tags were used on the commercial lobster 

 vessels. 



Several traps, modified to catch juvenile-sized lobsters, were fished 

 from the commercial lobster vessels. These traps were of plastic coated 

 wire construction and were fished along with the commercial wooden pots 

 on the trawls. 



Four of the 24 submersible dives were made on pot strings that had been 

 set for varying periods of time prior to the observation dive. Behavior of 

 lobsters, crabs, and associated fishes in and about the pots was documented 

 with color still photographs and video tape. 

 TOWED UNDERWATER BENTHIC SLED (TUBS) 



A towed underwater benthic sled (TUBS) , under development by the 

 Northeast Fisheries Center for six months, carried a new camera system 

 which took over 20,000 pictures of the ocean floor in the area of the cruise 

 operation. This activity, alternating with conventional trawling, repres- 

 ented the major portion of work aboard the Delaware II .
