the offshore fishery. There are other offshore 

 grounds that are fished by commercial ves- 

 sels. These include an area 35 km. southwest 

 of Hudson Canyon between the 200- and 400-m. 

 contours, and the Southwest Part, Southeast 

 Part, and north central areas of Georges Bank. 

 The oceanographic features of the area have 

 been reported by Colton, Marak, Nickerson, 

 and Stoddard (1968). The temperature at the 

 depths where lobsters are caught differs as 

 much as 5.0 C. between canyons. Generally 

 there is a cooling trend from west to east. 

 Periodically a tongue of water from the Gulf 

 Stream intrudes into the area of Oceanographer 

 and Lydonia Canyons, warming the bottom 

 water to somewhat higher temperatures than 

 occur westward at Veatch Canyon. Corsair 

 Canyon, far to the east, is consistently the 

 coldest area. 



Hudson Canyon 



Hudson Canyon (lat. 39 35' N., long. 

 72 25' W.) lies 100 km. south of eastern Long 

 Island, N.Y., and is the farthest west and south 

 of the sampled areas. The canyon was sampled 

 during research cruises in April, June, and 

 October 1967. Tows made at various depths 

 between 100 and 215 m. took a total of 907 

 lobsters (table 3). 



During the June cruise, six tows in the Hud- 

 son Canyon area caught 470 lobsters--an 

 average of 78 per 1 -hour tow. In October, 279
