Fishing Grounds of the Gulf of Maine

John Dyers Ridge. This lies 14 miles S. by E. from Toothakers Ridge, 40 miles S. by E. from Monhegan Island, and 7 miles NE. from Cashes Bank. It is about 5 miles long by 2 miles wide, lying in an ENE. and WSW. direction. The water is shoalest on the western edge, where are from 45 to 50 fathoms over a sharp, pebbly bottom; thence the ground slopes to the NE. into 75 and 80 fathoms over a hard, gravelly, and muddy bottom, in all other directions falling off sharply to 90 and 100 fathom soundings over a muddy bottom.

This is essentially a cod ground for the entire year, the species being most abundant from May 1 to November. It is a cusk ground all the year on the hard bottom of the deeper parts, March and April showing the largest schools. Hake also are abundant in 70 fathoms and deeper on the mud in summer and fall.
