catch is attributable largely to increasing vessel catches and the 

 development of otter trawling. 



4. The development of the New England otter-trawl fishery is 

 sunnnarized in Table 4. Beginning in 1905, from 1920 to 1927 its 

 catch averaged about one-half of the New England vessel catch and 

 was made by about 31 steam trawlers. Since 1920 longer trips have 

 been made with increased catches per trip. The catch per trawler 

 has been low since 1920, but was high again in 1927. 



5. The landings at Boston and Gloucester from various grounds 

 during the period 1891 to 1901 and 191C to 1925 are sunnnarized. in 

 Table 6. The total haddock catch does not show a decrease on 

 nearer grounds accompanied by increase farther afield. The line 

 fishery by itself does so, increases on the nearer grounds being due 

 to the otter-trawl fishery. 



('). Xo general or lasting depletion is evidenced by the available 

 .statistics. 



7. The geographical distribution of the Nortli American haddock 

 catch is shown in Figure 2. The catch is made chiefly from Cabot 

 Strait to Cape Cod, being greatest in the South Channel and the 

 vicinity. Large catches are made on Georges, Browns, and the Sable 

 Island Banks. With the exception of the head of the Bay of Fundy, 

 considerable catches are nuide along the entire coast from Cape Cod 

 to Cape Xorth. with large catches near Digby, Canso, and Ingonish. 

 Snudl catches are made in the southern part of the Gulf of St. 

 Lawrence.
