$23,087,000, and 16,343,000 gallons of body oils, valued at $18,476,000, were 

 produced. Liver and viscera oils, potent sources of vitamins, are derived mainly 

 from sharks, tuna, cod, halibut, lingcod, sablefish, and rockfish. The 1948 pro- 

 duction amounted to 740,137 gallons, valued at $12,507,652 (Tables 46 and 47). 

 Glue, condensed fish solubles— an evaporated product derived from the "stick- 

 water" formerly discarded in the wet process of producing meal and oil— pearl 

 essence, and marine plant products, etc., manufactured in 1948, were valued at 

 $9,285,458 (Table 48). From oyster and marine clam shells were manufactured 

 345,075 tons of crushed shell for poultry feed and unburned shell lime, valued at 

 $2,474,000 (Table 49). Fresh-water mussel shell products-buttons, crushed- 

 shell poultry feed, lime, and chips, shells, and novelties— were valued at $5,447,- 

 000 (Table 50). Marine pearl-shell buttons munbered 4,974,073 gross, valued 

 at $8,587,000 (Table 51). 



During the period from 1930 to 1948 the per capita consumption of fishery 

 products in the United States on an edible weight basis varied from a low of 

 8.2 in 1943 to a high of 12.0 pounds in 1936 (Table 52). Consumption during 

 the three war years, 1942-1944, ranged from 8.2 to 8.9 pounds, and in four 

 depression years, 1931-1934, from 8.9 to 9.5 pounds. All other years were 10.5 

 pounds or higher. Per capita consumption in 1948 amounted to about 11.5 pounds.
