FISHERY INDUSTRIES OF THE UNITED STATES, 1938 045 
similar manner. An agent is permanently stationed at Boston, 
Mass., and another is assigned to the ports of Gloucester, Mass., 
and Portland, Maine. Their duties include the obtaining of figures 
daily on the quantity of fish landed by each fishing vessel, the value 
of such fish landed, information concerning the date of departure and 
arrival of the vessel, and they also indicate the grounds from which the 
fish were taken and gear used in their capture. These data are for- 
warded to the Bureau, where compilations are made. Products of 
American fisheries received duty free at Boston and Gloucester, Mass., 
and Portland, Maine, from the treaty coasts of Newfoundland, Mag- 
dalen Islands, and Labrador are included in the landings at these 
ports: however, they are not included in the catch in sectional fishery 
surveys of the New England States unless thev represent a catch by 
United States vessels. Statistics of these landings are released 
monthly and annually in bulletin form and detailed data are pub- 
lished in the annual reports of this Division. Data on the landings 
at Boston, and Gloucester, Mass., have been collected annually 
since 1893, and those for Portland, Maine, since June 1915. Some 
data are available for Boston and Gloucester prior to 1893. 
Statistics of the landings of fish at Seattle, Wash., are collected by 
the Bureau’s agent in that city. Landings are classified as those 
made by United States fishing vessels and those received by Seattie 
wholesale dealers. The landings credited to United States fishing 
vessels are made by vessels operating distinctly as primary fishing 
units, usually in the offshore fisheries, while those credited as received 
by wholesale dealers are usually products of the shore fisheries col- 
lected mainly from points in Puget Sound and do not include fish 
received from Alaska or Canada, or landings made by the halibut fleet. 
Statistics of these landings at Seattle are released monthly and an- 
nually in bulletin form and detailed data are published in the annual 
reports of this Division. Statistics of the landings by fishing vessels 
at Seattle have been collected since June 1915 and certain data on 
products received by Seattle wholesale dealers since December 1915. 
Atlantic mackerel fishery.—Statistics on the catch by the Atlantic 
mackerel fleet are obtained by combining the figures of mackerel 
landed at Boston and Gloucester, Mass., and Portland, Maine, with 
those obtained by Bureau agents, who in recent years have been 
stationed at other Atlantic ports where mackerel are landed. These 
agents obtain data on the volume of mackerel landed in a manner 
similar to that used to obtain figures on the landings by fishing 
vessels at the three New England ports. The figures include only 
the catches made by purse seine and drift gill net craft and are not 
complete for craft of under 5 net tons’ capacity using this type of gear. 
Statistics of this fishery appear only in the annual reports of this 
Division, although the landings at the principal New England ports 
appear in the monthly and annual bulletins published for those ports. 
Statistics of this fishery are available from 1905 to 1937, inclusive. 
Shad and alewife fisheries—Owing to the importance of the Hudson 
and Potomac Rivers in the production of shad, surveys for statistics 
of the catch, value of the catch, and operating units are made an- 
nually. On the Potomac River similar statistics also are obtained for 
the alewife fishery. Much of the data required for these surveys are 
available from the State fishery agencies.
