Fishing Grounds of the Gulf of Maine

Rock Cod Ledge. This ledge lies NE. of Seal Island 1 mile. It has a depth of 3½ fathoms on the shoalest part, deepening gradually on all sides for a considerable distance. The bottom is of sharp rocks and is broken in places.

Rock cod are present in fair numbers in spring and fall, and this is a mackerel and herring ground in their seasons. Haddock are abundant in the fall close in to the rocks of Seal Island in 6 to 15 fathoms. This is not a hake ground, although there are a few cusk to be had here on the deeper parts and an occasional small halibut is taken in the kelp on the shoal in June and July. It is a good lobster ground.
