Fishing Grounds of the Gulf of Maine
Blue Ground. This is SE 1 ½ E from Monhegan, distant 14 miles; E 1 ½ S from Portland Lightship 45 miles, and SW from Matinicus Rock 9 miles to southern Edge. Fishermen usually take the Monhegan bearing for their starting point.
This ground has a small shoal in the center, having 28 to 30 fathoms, from which the bottom slopes off to 45 and 60 fathoms on the edges. The shoal is broken and rocky, bu the deep water is over a level gravelly bottom. This ground is circular in form and about 2 miles across. It is both a small-boat and vessel ground, larger craft operating here mainly in the fall.
Hake are found here in large numbers in summer and fall; cusk are taken in the deep water the year around but are most abundant in January. Cod are here the year around, the largest school occurring in February and March.
