232 U.S. BUREAU OF FISHERIES 



landed headless and eviscerated ; some salmon, especially that caught 

 by troll lines, may be eviscerated; ''lingcod", rockfishes, and sablefish 

 may be landed eviscerated. The weight of cod caught off Alaska 

 and shown in the Pacific coast tables has been converted to the basis 

 of round weight. 



Bulletins containing statistics for each section are released following 

 the survey. 



Landings at certain important United States ports. — Statistics of the 

 landings at the principal New England ports (Boston and Gloucester, 

 Mass., and Portland, Maine) are similarly obtained. An agent is 

 permanently stationed at each of these ports. His duties include 

 the obtaining of data on the quantity of fish landed each day by each 

 fishing vessel, the value of such fish landed, information concerning 

 the date of departure and arrival of the vessel, and he also indicates 

 the grounds from which the fish were taken and the gear used in their 

 capture. These data are forwarded to the Bureau, where compila- 

 tions are made. Monthly statistical bulletins are issued for these 

 landings as well as annual bulletins summarizing the year's activities. 



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 American fishing vessels and those received by Seattle 

 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. Monthly statistical bulletins are issued for these landings as 

 well as annual bulletins summarizing the year's activities. 



Statistics on the landings of fish at New York City are obtained 

 from J. H. Matthews, executive secretary of the Middle Atlantic 

 Fisheries Association, while those for Groton, Conn., are obtained 

 by the Bureau's agents. Statements of these landings are forwarded 

 to the Bureau, where they are compiled. These statistics have not 

 included the value of the catch. Monthly bulletins including these 

 data are not issued; however, a summary is published in this 

 document. 



Statistics of the fishery products handled at the municipal wharf, 

 Washington, D.C., are reported to the Bureau by agents of the city 

 health department. They are not published in bulletin form, but a 

 sumniary of the year's activities is published in the annual report of 

 this Division. 



Atlantic mackerel fishery.- — -Statistics on the catch by the Atlantic 

 mackerel fleet are obtained by combining the figures of mackerel 

 landed at Boston and GTloucester, Mass., and Portland, Maine, with 

 those obtained by agents who in recent years have been stationed at 

 other Atlantic ports where mackerel are landed. These agents 

 obtain data on the fares of mackerel landed, similar to the data obtain- 

 ed 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 these gears for craft under 5 net 

 tons capacity. 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.
