On and about all these shoals the sail fleet makes good catches, mainly consisting of cod but with a fair proportion of pollock, also, and in the deeper water close to them, in spring and summer, a considerable amount of haddock. An occasional large halibut is taken, and even good catches have been reported. There were noted in the daily report of the Boston Fish Bureau between May 15 and August 15, 1920, 10 trips made by the smaller vessels of the halibut fleet that landed fares of from 2,000 to 10,000 pounds of this species from this area. Perhaps more would be taken if the halibut fishery were to be followed here as in other areas. "Rip fishing," as conducted here, is done "at a drift," moving over the shoals and, as they move off from them, sailing back to repeat the process. The fish are taken by hand-lining with "cockle" bait or by "jigging" the fish with a shiny piece of metal representing a herring or similar fish, below which are set twin hooks, the fish being struck when it is felt investigating the lure. This fishery generally is carried on during May, June, July, and August. In the mackerel and herring seasons these grounds usually furnish good fishing for these species, the fish usually striking here from May 15 to July 15. Pollock Rip Grounds. These lie between Pollock Rip Lightship and Shovelful Lightship and extend northward to Pollock Rip Shoal. These grounds are 3 miles long, E. and W., by 2 miles N. and S. The depths range from 4 to 12 fathoms. These are fished from Monomoy and in stormy weather from Chatham instead of going to the Crab Ledge. Late in the spring and early in the fall the cod move inshore. In winter the cod leave Pollock Rip for the deeper water. Rose and Crown Shoal. This is a small piece of ground 7 miles ESE. from Sankaty Head. The fishing area lies between the Round Shoal and Rose and Crown buoys, making a stretch perhaps 6 miles long by 1 1/2 miles wide. Sometimes good fishing may be had from 6 to 12 mile, from Great Round Shoal buoy. As elsewhere on and about these shoals, the cod is the principal species caught, pollock being next in importance, and a few haddock. Nantucket Shoals, Madisons Spot. SSE. 13 miles front Round Shoal buoy, has 9 fathoms over a smooth hard bottom of sand. It is about 3 miles long, from SE. to NW. by 1 1/2 miles wide. This is a flounder ground for the greater part of the year and a good cod ground in October and November. As is the rule elsewhere in this neighborhood, tides are heavy over this ground.
