The data in this edition of "Fishery Statistics of the United States" were collected in co- 

 operation with the various States and tabulated by the staff of the Statistics and Market News Di- 

 vision under the direction of HoytA. Wheeland . The material was prepared for publication by Thelma 

 I. Bell and Susan Flint. Field surveys were supervised by the various regional and area offices. 

 Program leaders in charge of field surveys were: Francis Riley for the New England, Middle Atlan- 

 tic, Chesapeake, Great I^kes, and northern Mississippi River States; George Snow for the South 

 Atlantic, Gulf, and southern Mississippi River States; James R. Bybee, California; Victor J. Samson,

PREFACE 



This report contains a review of the fishery statistics for the year 1970. These statistics 

 include data on the volume and value of landings of fishery products, employment in the fisheries, 

 quantity of gear operated, number of fishing craft employed in the capture of fishery products, in- 

 formation on the volume and value of the production of processed fishery products, data on freez- 

 ings and cold storage holdings, and on foreign trade in fishery commodities. 



Data on employment of fishermen, fishing craft and gear in the fisheries, and on the land- 

 ings of fish, shellfish, and other aquatic plants and animals, are shown for States having commer- 

 cial fisheries . There is also information on the pack of canned tuna and industrial products for 

 Puerto Rico and American Samoa included in the processed products tables. In Section 11, Puerto 

 Rico landings data are also shown. 



In all of the landings tables in this report, except theoneon page 42 entitled, "U.S. Land- 

 ings, 1970-Live Weight Basis," the volume of fish, crustaceans, and such moUusks as squid is 

 shown in round (live) weight. However, the weights shown for univalve and bivalve mollusks 

 (cohchs, clams, oysters, scallops, etc.) represent the weights of meats, excluding the shell. 

 The weight of shells omitted from the catch in 1970 amounted to about 1.2 billion pounds . It should 

 be noted, however, that the data in the table on page 43 "World Landings of Fish, Crustaceans, 

 Mollusks, etc. , by Countries" are shown on a live weight basis. 



All appropriate records collected by the various State fishery agencies were used in assem- 

 bling data on the fisheries . In certain areas , information complete enough to be used by the sta- 

 tistical agents was available from State agencies, and in these States, only partial surveys were 

 conducted. Information on the means of collecting the data and an explanation of terms used may 

 be found in Section 13 of this publication. 



Complete statistical surveys covering the fisheries of the United States wereconducted in 

 all areas for 1970. The first complete survey of the fisheries of the United States was made by the 

 Bureau of the Census for 1908. Others were made by the Bureau of Fisheries and the Fish and Wild- 

 life Service for the years 1931, 1950, 1954-60, and 1962-69.
