J Includes 3 Canadian vessels. 



Otter trawls, medium vessels. — A fishery with otter trawls was also 

 prosecuted by 73 vessels of 21 to 90 net tons, inclusive, in 1930. 

 Medium otter trawls are referred to by some in the fisheries as "drag- 

 gers." These vessels made 727 trips to 9 main fishing grounds and 

 were absent from port 4,652 days, or an average of 6.4 days per trip. 

 Their catches aggregated 20,320,439 pounds, or about 6 per cent of 

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

 constituted 64 per cent; flounders, 19 per cent; and cod, 14 per cent. 

 Only small quantities of other fish were brought in by this type of 

 vessel. Of the total catch, 45 per cent were taken on Georges Bank, 

 and 39 per cent on South Channel. Only small quantities were taken 

 on the other banks where these vessels fished. 



Otter trawls, small vessels. — A fishery with otter trawls was also 

 prosecuted by 69 vessels of 5 to 20 net tons, inclusive, in 1930. 

 Small otter trawlers are referred to by some in the fisheries as 

 "flounder draggers." These vessels made 547 trips to 7 main fishing 

 grounds, and were absent from port 2,014 days, or an average of 3.7 

 days per trip. Their catches aggregated 4,834,017 pounds, or a httle 

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

 this amount, 49 per cent consisted of flounders and 33 per cent of 

 haddock. Considerable quantities of cod and hake were also brought 

 in by these vessels. Of the total catch, 57 per cent were taken on 

 banks along the shore, and 22 per cent on South Channel. Catches 

 by this type of vessels on the other banks where they fished were very 

 small. 



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

 trawls was prosecuted by 51 vessels of 91 net tons and over in 1930. 

 The large number of vessels operating V-D trawls in 1930 is due to 

 the fact that many of the regular otter- trawl vessels also carry a V-D 

 type of trawl and for this reason there is some duplication within the 

 large otter-trawl group and the large V-D trawl group. These vessels 

 made 790 trips to 10 main fishing grounds, and were absent from port 

 7,206 days, or an average of 9.1 days per trip. Their catches aggre- 

 gated 58,693,591 pounds, or 17 per cent of the total landings by vessels 

 at the three ports. Of this amount 72 per cent consisted of haddock, 

 18 per cent of cod, 4 per cent of flounders, 2 per cent of hake, and 2 

 per cent of poflock. Of the total catch, 57 per cent was taken on 

 Georges Bank and 24 per cent on South Channel.
