stance, on Grand Manan Bank, on Jeffreys Ledge, and on Stcllwagcn Bank at the 

 entrance to Massachusetts Bay. 



They are also caught regularly by the line trawlers and in less amount by the 

 otter trawlers on all the offshore fishing grounds, but as a rule the catches brought 

 in thence are insignificant compared with those of the inshore fishery, as the follow- 

 ing figures for 1919, a fairly representative year, will illustrate:

Sometimes, however, larger quantities are 

 brought in from one or the other of the outer 

 fishing groimds than in the year just analyzed — 

 3,260,000 pounds from the South Channel in 

 1921, for example. In the grand total the yield 

 of pollock may be expected to average at least 

 35,000,000 to 40,000,000 pounds for the whole 

 Guff of Maine— say 5,000,000 to 6,000,000 fish, 

 taking one year with another. 



Small pollock 4 to 10 inches long and weigh- 

 ing less than half a pound (that is, 1 or 2 years 

 old) swarm inshore after early April, when we 

 have seen thousands taken from the traps at 

 Gloucester and Magnolia. In the southern part 

 of Massachusetts Bay these "harbor pollock," FlG . 2 02.-Monthi y landings of fresh pollock at

probably to avoid the rising temperature, to work back in autumn, but they remain 

 very abundant all summer and autumn in the harbors and bays and among the 

 islands all along the coast from Gloucester north and east to Nova Scotia. In 

 winter, however, most of them seek slightly deeper water, probably to avoid the cold. 



The larger fish, as is usually the case, keep farther offshore than the small 

 ones, and on the whole live deeper except when pursuing some particular feed 

 (p. 401). They are caught in more definite localities — not everywhere and any- 

 where along the coast as the little immature fish are. In the southern part of the 

 Gulf, as exemplified by Massachusetts Bay and the belt from Cape Ann to the 

 Isles of Shoals, large pollock are taken in greatest number in late autumn and early 

 winter when the gill-net fishery taps the spawning fish (fig. 202), and they often 

 appear in abundance near land during April and May. However, they so generally 

 move out and into deeper water as the surface warms up with the advance of the
