Fishing Grounds of the Gulf of Maine
Big Ridge, or Doggetts . -These names are given to a piece of fishing ground about 8 miles long by 2 miles wide lying 18 miles SE. by S. ½ S. from the lightship at Portland or 14 miles SE. by E. from the same point, according to which part it is desired to fish upon. It has from 45 on the shoal in the center to 8O fathoms of water on the deeper parts over a bottom of rocks and gravel on the shallower portions and of mud about the edges and in the deeper soundings.
Cod are abundant here in spring and fall on the shoaler parts of the bank and are present the year around on the muddy edges and in the deep water about it; the spring school, however, is the largest. Hake are found in spring and summer on the edges in deep water. A few haddock may be taken in the winter and spring, January to April, inclusive. Cusk can be taken the year around, the best fishing being in spring and winter. The February cusk school is the largest, and the best catches are made in the deep water about the edges of the ground. Fishing here is principaIly by trawling, but hand-lining and gill netting also are employed, the latter method in continually increasing volume.
Lying off Cape Porpoise, between the bearings of SE. and SSE., and at distances varying from 6 to 8 miles, are a number of small, rocky, or pebbly bottoms having depths ranging from 18 to 25 fathoms. During certain seasons these abound in cod and haddock and are visited by the fishermen of the vicinity.
