TABLE 19. Catch of cod off the east coast of North America
2 Italian vessels fished only during the first half of 1940 owing to Italy's entry into the war.
(U. S. Department of the Interior, Fish and Wildlife Service, June 1, 1948)
SPECIAL DATA ON THE NORTHWEST ATLANTIC FISHERIES
Tables appended consist of data on haddock, rosefish, cod, and halibut referring to: (a) Changes in average sizes; (b) relationship of value to size; (c) changes in fishing effort as shown by distances traveled; (d) relative importance of each bank. Tables 1 to 3 are data on yearly change in average size. Tables 1 (haddock) and 2 (rosefish)_ have been determined by actual measurements of the sizes of fish landed. Table 3 represents an attempt to estimate yearly change for the cod, from data on relative pounds of each market classification (large market and scrod) landed, inasmuch as no market measurements have been made on this species. No data on halibut are available as all halibut are in one market classification and no length or weight measurements of these have been made.
Tables 4 (haddock) and 5 (cod) are data on the relationship of value to size. No data on rosefish or halibut are available as these fish are marketed as in single-size group.
Tables 6 to 10 deal with changes in fishing effort as shown by distances traveled. Distances are from Boston. These tables do not refer to any particular one of the four species. Table 6 is a grand summary of all years, all gear. Table 7 is all gear also, but is broken down by years. Tables 8, 9, and 10 are each broken down by years; table 8 giving data on all otter trawls; table 9 all data on handliners; table 10 all data on line trawls.
Tables 11 to 14 deal with relative importance of each major fishing bank for each of the four named species. Table 11 gives the landings by fishing area for haddock; table 12 for rosefish; table 13 for cod: and table 14 for halibut.
"New England fisheries" or "New England ports" refers to the ports of Boston, Gloucester, and Portland except for 1946, where it refers to these ports plus New Bedford and Cape Cod.
