1066 U. S. BUREAU OF FISHERIJIS 



by each fishing vessel, the vahie of such fish landed, information 

 concerning the date of departure and arrival of the vessel, and also 

 a list of the grounds from which the fish were taken and the gear 

 used in their capture. These statistics are forwarded to the bureau, 

 where compilations 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 at that place. Landings are classified as those 

 made by American fishing vessels and those received by Seattle 

 wholesale dealers. The landings credited to American fishing ves- 

 sels are made by vessels operating distinctly as primary fishing units, 

 usually in the oft'shore fisheries, while those credited as received by 

 wholesale dealers are usually products of the shore fisheries collected 

 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 bull-etins are issued for these landings as well as 

 annual bulletins summarizing the year's activities. 



Statistics of the combined landings of fish at New York City and 

 Groton, Conn., are obtained by J. H. Matthews, executive secre- 

 tary of the Middle Atlantic Fisheries Association. 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 herewith. 



Statistics of the fishery products handled at the municipal wharf, 

 Washington, D. C, are reported to the bureau daily by agents of 

 the city health department. These are compiled on an annual basis. 

 They are not published in bulletin form, but a summary of the year's 

 activities is published in the annual report of this division. 



Canned fishery products and by-products. — Beginning in 1921, the 

 bureau has made annual surveys for statistics of the canned fishery 

 products and by-products industries. These are begun the first 

 week in January of each year for statistics of the production in the 

 preceding year. The surveys occupy usually 6 to 9 weeks' time. 

 During this period agents visit each plant in the United States where 

 there is a production of canned fishery products or by-products. 

 They obtain statistics of the production and value of the production 

 for each commodity. In rare instances, where plants are not easily 

 reached by regular transportation facilities, returns are obtained by 

 mail. 



Statistics on the production of fresh-water mussel shell products, 

 which include pearl buttons, crushed shell for poultry feed, lime, cut 

 shells, stucco, and colored shell chips used for decorative purposes, 

 were included in this survey for the first time in the data for 1929. 



The value shown for canned products constitutes the gross amount 

 received by the packer at the production point, no deductions being 

 made for commissions or expenses. 



Statistics of the canned fishery products and by-products produced 

 in Alaska are received on the same sworn statements that include 

 statistics of the general fisheries. An annual statistical bulletin is 

 issued on this trade.
