V-D trawls (otter trawls), medium vessels. — A fishery with V-D otter 

 trawls was prosecuted, by 64 vessels of 21 to 90 net tons, inclusive, in 

 1930. These vessels made 1,101 trips to 10 main fishing grounds, and 

 were absent from port 8,697 days, or an average of 7.9 days per trip. 

 Their catches amounted to 43,902,614 pounds, or about 12 per cent 

 of the total landings by vessels at the three ports. Of this amount, 

 80 per cent consisted of haddock, 12 per cent of cod, and 4 per cent of 

 flounders. The remainder was made up chiefly of hake and pollock. 

 Of the total catch 56 per cent were taken on Georges Bank and 36 

 per cent on South Channel. Only minor quantities were taken on the 

 other banks where these vessels fished. 



V-D trawls (otter trawls), small vessels. — A fishery with V-D otter 

 trawls was prosecuted by 2 vessels of 5 to 20 net tons, inclusive, in 

 1930. These vessels made 11 trips to 3 main fishing grounds and were 

 absent from port 89 days, or an average of 8.1 days per trip. Their 

 catch, aggregating 274,899 pounds and consisting almost entirely of 

 haddock, was taken principally on Georges Bank and South Channel. 



Sink gill nets. — A fishery with sink gill nets was prosecuted by 39 

 vessels in 1930. These made 3,614 trips to Jeffreys Ledge and banks 

 along the shore and were absent from port 3,635 days, or an average 

 of about 1 day per trip. The catch amounted to 16,793,933 pounds, 

 or about 5 per cent of the total landings by vessels at the three ports. 

 Of this amount, 53 per cent consisted of pollock, 28 per cent of cod, 

 10 per cent of haddock, and 8 per cent of hake. Practically the entire 

 amount was taken on those banks along the shore. 



Drift gill nets. — A fishery with drift gill nets was prosecuted by 90 

 vessels in 1930. They made 732 trips to Bay of Islands and banks 

 along the shore and were absent from port 1,520 days, or an average 

 of 2.1 days per trip. Their catch amounted to 3,523,617 pounds, or 

 about 1 per cent of the total landings by vessels at the three ports. 

 Of this amount about two-thirds consisted of herring, which were 

 taken on Bay of Islands, and one-third of mackerel taken mainly on 

 grounds near the shore. 



Purse seines. — A fishery with purse seines (mackerel fishery) was 

 prosecuted by 1 13 vessels in 1930. This is the same number that oper- 

 ated in 1929. They made 1,543 trips to 10 main fishing grounds and 

 were absent from port 4,220 days, or an average of 2.7 days per trip. 

 Their landings at the three New England ports amounted to 34,667,329 

 pounds or 10 per cent of the total landings at the three ports. Of this 

 amount, 93 per cent consisted of mackerel, and 3 per cent of herring. 

 Of the total, 46 per cent was taken on grounds near the shore and 40 

 per cent on South Channel. Considerable quantities were also taken 

 off Chatham and on Nantucket Shoals. 



Scallop drags or trawls. — A fishery with scallop drags or trawls was 

 prosecuted by 4 vessels in 1930. These made 5 trips to Boston and 

 were absent from port 24 days, or an average of 4.8 days per trip. 

 The catch consisted of 21,807 pounds of scallop meats. These were 

 obtained from scallops taken on Nantucket Shoals, Georges Bank, and 

 South Channel. 



Summary. — In general, the otter trawls and V-D trawls were the 



most important gear used by vessels landing fish at the three New 



England ports, catching 61 per cent of the total landings. Line 



trawls were next in importance, catching 21 per cent of the total.
