Purse seines were third, with 10 per cent of the total. Sink gill nets 

 accounted for 5 per cent and hand lines, harpoons, drift gill nets, and 

 scallop drags the remaining 3 per cent. 



Among the fishing grounds Georges Bank was of most importance, 

 furnishing 42 per cent of the fish caught by the vessels. South Chan- 

 nel, which is near Georges Bank, was second, and furnished 26 per 

 cent. About the same per cent of the total landings was caught on 

 these banks during the year 1929. Shore grounds furnished 12 per 

 cent. Browns Bank, 9 per cent; La Have Bank, 3 per cent; and Nan- 

 tucket Shoals, 2 per cent. All of these grounds, except La Have Bank, 

 are off the United States. The catch on any one of the other banks or 

 grounds, where fishing was prosecuted by vessels, furnished less than 

 4,000,000 pounds each. 



The fishery products landed at the three ports by vessels are taken 

 chiefly on fishing grounds off the United States west of 66° west longi- 

 tude. In 1930 these grounds furnished 93 per cent of the total land- 

 ings by vessels at the three ports. Those fishing grounds off the 

 Canadian Provinces east of 66° west longitude furnished 6 per cent; 

 while those off Newfoundland, also east of 66° west longitude, fur- 

 nished about 1 per cent. 



The large catch on grounds off the United States is influenced by 

 the large catches by otter trawls on Georges Bank, South Channel, 

 Browns Bank, and Nantucket Shoals, which fishing grounds are suited 

 to this type of gear, and which are comparatively near packing centers. 

 Compared with 1929, there was a decrease of 5 per cent in the landings 

 of fish taken on grounds off the United States, an increase of 118 per 

 cent of the landings of the fish taken off Canadian Provinces, and an 

 increase of 53 per cent in the landings of fish taken off Newfoundland.
