Fishing Grounds of the Gulf of Maine

Ipswich Bay .-This extends from the north side of Cape Ann about to Portsmouth and is resorted to in winter by large schools of cod coming here to spawn. Shore soundings deepen here gradually from the land, reaching 35 to 40 fathoms at 6 or 7 miles out. Within this limit the bottom is mainly sandy, though rocky patches are numerous between Newburyport and Cape Ann. Beyond 40 fathoms the bottom Is mainly mud.

The principal cod-fishing grounds of Ipswich Bay lie off the northern shore, from Newburyport to the entrance of Portsmouth Harbor, 1 to 5 miles off the land In 12 to 25 fathoms. Cod are taken abundantly off Boars Head, also. During 1923 and 1924 the cod fishing in these waters, especially off Boars Head, was the best for some years.

Fishing is done by trawls and hand-lining, and of late years a large and increasing gill-netting fleet has operated in these waters, especially from March to June.

The muddy ground outside these waters Is a hake ground much frequented by small boats and vessels from the Isles of Shoals and Cape Ann during the summer and fall.

"Flounder dragging" Is a considerable industry in these waters, the craft employed being a small type of the otter trawler, mainly operating out of Newburyport on a piece of shallow mud bottom extending from NE. by E. to SE. of the Isles of Shoals and on another ESE. from Thacher Island. Depths are from 4 to 14 fathoms.
