FISHERY INDUSTRIES OF THE UNITED STATES, 1936 971 
production in bushels. These supplementary tables also give the 
production of certain other shellfish, such as crabs, in number. 
_Oysters.—Probably the greatest problem in presentation of fishery 
statistics in uniform units of measure is in the case of oysters. Usually 
the production of oysters on the Atlantic and Gulf coasts is reported to 
Bureau agents in bushels; and prior to the data obtained for the year 
1930 conversion from bushels to pounds of meats was effected on the 
basis of a uniform yield of 7 pounds of meats to the bushel. However, 
more recent investigations have shown considerable variation from 
this figure. There follows a table which gives the results of these 
studies of the measures used for oysters in the various States and of 
the average yields per bushel. This table presents the factors that 
have been used in the oyster statistics given in this report.
