BY-PRODUCTS 



The output of fishery by-products in Cahfornia was vahied at 

 $4,022,042 m 1928. Under this desig^nation are inckided fish meal and 

 scrap; tuna, sardine, and whale oils; agar-agar; and other miscel- 

 laneous fishery by-products. Sardine oil was the most important 

 item, the production being valued at $1,621,531. Next in importance 

 was fish meal and scrap, the production of which was valued at 

 $1,614,515. The products of the whale industry were valued at 

 $296,000. The oils and meals are manufactured at the canneries 

 from whole fish unsuitable for canning, from the surplus, or from offal. 

 The whale products result from operations of whale fisheries. In 

 1928 one floating whaling factory was operated by Cahfornia interests 

 oft' wSan Clcinente Island in southern California. Four killer boats 

 worked with this factory, obtaining 304 whales, which produced 

 633,848 gallons of whale oil. This is a somewhat greater quantity 

 than was produced for several years previous to 1928, but was less 

 than that for 1922. 



A large percentage of the fish meal produced is used as a constituent 

 of poultry feed, most of it being marketed in Cahfornia. The oils 

 are used in the manufacture of paints and soaps, and some is hydro- 

 genated into margarine for use in cooking. vSan Pedro and Monterey 

 are the principal points for the production of fish meals, and sardine 

 and tuna oils.
