Fishing Grounds of the Gulf of Maine by Walter H. Rich (e reader .TXT) 📕

Maurice Lubee's Ground. This lies outside of New Ledge (Platts Bank) 47 miles SSE. from the lightship at Portland. Extending in an ENE. and WSW. direction, its boundaries are somewhat indefinite. It is perhaps 8 miles long by 3 miles wide and has depths from 95 to 110 fathoms over a bottom consisting mostly of mud.

Cusk are plentiful here in the spring, with a few in the fall. Cod are taken all the year around, the Spring school being the largest. Hake are most numerous In the spring and fall months, and haddock are not common but are most numerous in winter.

Apparently the abundance of cod on this ground is due to the great quantity of shrimps and soft-shelled crabs found on the muddy bottom and on the rocks that compose this ground. There seem to be many of these deep-water grounds between and about the shoaler grounds, as near Cashes, Fippenies, and Jeffreys, which apparently serve as fairways over which the schools of hake, cod, and cusk, move from Georges Bank into the Gulf of Maine in the spring of the year.

Harvey Blacks Ridge. This is SE. ½ S. from the lightship off Portland, distant 42 miles, and SE. from New Ledge, distant 8 miles. From Glovers Rock, off Small Point, Me. this ridge lies SE. by S. ½ S. 41 miles. It extends in an ENE. and WSW. direction about 4 miles long by I mile wide. Depths average 70 to 100 fathoms over a bottom of yellow clay and gravel. Cod are taken here all the year. Haddock are found in the deep water in the spring: cusk all the year in deep water, together with hake in summer, also on the muddy bottom in deep water. Pollock and other surface-schooling fish are found here in their proper season.

The Cod Ridge (formerly Outer Harris Ground). This lies NE. from the Northeast Peak of New Ledge, distant 7 miles. It extends in an ENE. and WSW. direction, the ground narrowing and the water deepening to the eastward, the shoal ground having 45 fathoms on a bottom of small pebbles and fine black gravel and sand, depths increasing in all other directions to 100 fathoms on the mud and sloping off somewhat steeply, especially on the southeast side, where the drop is very sharp. The length of the ground is about 5 miles, the width 1 mile. This is an all-the-year cod ground, the season of greatest abundance being from May 1 to November. The haddock are usually In their greatest numbers here from January 1 to April. Apparently no large number of cusk or hake are taken here on the ridge, perhaps because the water is not deep enough for the former, except for the small fish, which are of little value to the fishermen; and the ground is not muddy enough for the latter species. Both species, however, are found about the edges in the deep water, the cusk on the sharpest, hardest part of the bottom (perhaps most common in February and March), the hake, as usual, on the muddy parts about it.

Three-Dory Ridge. Outside of New Ledge and about midway between it and Harvey Blacks Ridge is a small ridge about 3 miles long, running NE. and SW., and about ½ mile wide. This lies SE. by S. from the Portland Lightship. 38 miles to the shoal of 55 fathoms, which is near its center. From this the ground slopes away on all sides to 63 and 65 fathom depths over which area the bottom is made up of sand, gravel, mud, and rocks. At these lower depths are found "pipes" (clay cylinders), where the fishing ends abruptly. All about the ridge are depths of 80 to 100 fathoms on a bottom of mud. This is almost entirely a cod ground, good from May to August.

Platt's Bank or New Ledge. This bears E. by N. ½ N. from Thacher Island, from which the shoal portion of the ledge is distant 53 miles. From Portland Lightship it is 30 miles SSE. to the center of the ground. The bank is about 12 miles long, NE. and SW.. and about 8 miles wide. The western shoal, which is of small extent and rocky and which has a considerable amount of dead shells upon it, is situated near the center, its depth being 29 fathoms. From this shoal to the Southwest Peak is about 11 miles SW. by S. Another shoal lies E. 3 miles, having about 30 fathoms over sand and gravel, which is a good fall ground for haddock. East-northeast from the western shoal 3 miles brings us to a rocky ridge, with spots of hard mud and pebbles between, in 65-fathom depth, which is a fine winter cusk ground, these fish remaining here until April. Over much of the bank the depths range from 30 to 35 fathoms with a bottom of rocks and gravel. From the edge of the shoaler area the bottom slopes gradually to 50 or 60 fathoms, beyond which it drops suddenly to 80 or 90 fathoms over a muddy bottom.

This was considered one of the very best fishing grounds for cod and haddock in the Gulf of Maine, but the haddock catch here has fallen off recently. Hake also are very abundant during the summer months and often during October on the muddy bottom near the edge. Inside 100 fathoms, on a "punkin" bottom of rocks and gravel, near the mud, haddock are found from December to March. Cod, pollock, and cusk occur from May to October, the former on the rocky and gravelly portions, the latter on the deep soundings, with the Northeast Peak the best summer ground. This is also an especially good fall and winter ground for haddock. Halibut are often found in 35 fathoms (small fish) from September through November; also In spring and early summer. This ground is fished by vessels from Cape Cod, Mass., to Cutler, Me., mainly by trawling, some hand-lining, but no gill netting of importance as yet.

Jeffreys Ledge. Jeffreys Ledge may be considered one of the best fishing grounds in the Gulf of Maine, although of comparatively small size. It appears to be an extension of the shoal ground that makes off in an easterly direction from Cape Ann, it is about 20 miles long in a NE. and SW. direction and about 4 miles wide. Its southern limits is 42° 54' and its northern limit 43° north latitude; its eastern and western boundaries may be placed at 69° 58' and 70° 18' west longitude. The bottom is rocky on the shoaler parts, with gravel and pebbles on the edges. Depths on the bank are from 27 to 35 fathoms, falling off to 40 or 50 on the edges. The shoalest water lies from 4 to 5 miles N. by E. from the buoy, where there is 22 fathoms. Ordinarily there is little or no tide, with an occasional current SW. There are, however, strong westerly currents with the heavy easterly winds, and often after a period of mild weather with no strong tides there will suddenly develop a heavy SW. flow, indicating the approach of a strong northwester. This seems a general rule in the Gulf of Maine and is, perhaps, prevalent over much of our North Atlantic coast.

Jeffreys Ledge bears S. ½ W. from the lightship off Portland, 19 miles to the northern edge and 22 miles S. from the buoy on the Hue and Cry to the edge of the shoal.

A small cove makes for a short distance into the western side of Jeffreys Ledge at about 20 miles from Boon Island in a SE. by S. ½ S. direction. The bottom in the cove is broken and muddy, with depths of about 60 fathoms. Thence, the ground slopes away to the mouth, where the edges about the entrance are rocky and have 70 and 75 fathom depths. These rocky areas are cusk grounds in January, February, and March, during which months the cove itself usually furnishes good haddock fishing. Outside these depths the water deepens westward over a muddy bottom, where are from 80 to 90 and even 100 fathoms of water. Fishing here is mainly by trawl and gill nets.

Lying about SE. by S. ½ 5. from the Isle of Shoals 20 miles, 13 miles S. by W. from the whistling buoy on Jeffreys, and 43 miles S. by W. from Cape Elizabeth is a broken piece of bottom having from 75 to 85 fathoms of water over it, which is a haddock ground from January to April and a cusk and hake ground all the year.

A small shoal in the western part of the Cove of Jeffreys, having 50 fathoms over a bottom of blue clay and rocks and rising from the 60 and 70 fathom soundings about it, is about 1½ miles long by about 3/4 mile wide. This shoal is SSE. from Boon Island 15 miles. It is a winter ground for cod and haddock.

Clay Ridge. At various points about the edges of Jeffreys Ledge are small detached ridges, which in their season are good fishing grounds. The present piece of ground lies 26 miles S. by W. from the lightship at Portland, which course and distance bring us to the northern edge. There is a 50-fathom shoal of small size upon it, but elsewhere soundings average from 65 to 70 fathoms over a bottom of hard clay. The length of the ground is about 4 miles NNE. and SSW., and the breadth about 1 mile. This furnishes good haddocking in January, February. and March. the latter month showing the best fishing.

Jerry Yorks Ridge. This lies just inside and paralleling Jeffreys Ledge WNW. from its shoal water and about 5 miles distant from the ledge and about 18 miles SE. by S. ½ S. from Cape Porpoise. This ground has from 45 to 48 fathoms of water on a rocky broken bottom. It is about 5 miles long, NNE. and SSW., and averages 1½ miles wide. This is a good cod and haddock ground In the fall and up to January, these fish returning here in the spring months.

Howard Nunans Ridge. Of similar nature to the last, this rises 4 miles inside of and parallel to it, lying 14 miles from Cape Porpoise on the same bearings (SE. by S. ½ S.). This appears to be made up of two shoals, the northern rising to 50 fathoms of water over a rocky, broken bottom about 3 miles long by 1 mile wide, deepening southwesterly to a narrow, muddy gully, where are 80 fathoms, and rising again to 60 fathoms over rocks and broken ground. The whole ground is about 8 miles long with average widths of from 1 to 1½ miles. This ground furnishes good cod fishing and haddocking in the fall and early winter and again in the spring months.

Southeast Jeffreys. Off the southeast edge of Jeffreys, about 24 miles SE. from Boon Island, lies a piece of fishing ground having a hard bottom of sand, gravel, and rocks, where depths slope away gradually from the 50-fathom soundings near the main body of the bank to the 90-fathom mark farther out. This area is a good ground for cod and haddock in the winter and spring and a hake ground in March. This fishing spot is about 3 or 4 miles square and is bounded on all but the western side by muddy bottom, which is of little value as a fishing ground. Usually there is good haddocking in March on the outside of Jeffreys, on its southeastern edge and in the cove between it and Tillies in 60 and 70 fathom depths on a broken and muddy bottom. This spot lies SE ½ from the Isle of Shoals, 27 miles to the center.

Eastern Shoal Water of Cape Ann. This is generally considered a part of Jeffreys and is often spoken of
