HERRING IN PRINCE WILLIAM SOUND, ALASKA 
265 
In 1921 the prices of fish oil and fish meal were so low that the Thumb Bay plant 
did not operate the reduction unit, and the Port Ashton plant utilized but 1,900,000 
pounds in this manner. The amounts used for pickling increased, however, from 
Figure 3. — Past and present fishing grounds of Prince William Sound. The more important grounds are indicated by heavier 
circles. 1, Kiniklik; 2, Port Fidalgo; 3, Perry Island; 4, Naked Island; 5, Port Gravina; 6, McClure Bay; 7, Main Bay;

9,200,000 pounds in 1920 to 16,700,000 pounds in 1921, in spite of the loss by fire of 
the W. J. Imlach plant at Port Benny in Evans Bay. 
The success met with in marketing the 1921 pickled herring pack resulted in 
more operators establishing plants in this district in 1922. The number of plants 
increased from 5 in 1921 to 9 in 1922 (a very small amount was also pickled at Cor- 
dova), and the number of purse seine boats employed increased from 9 to 18. (Table 
2.) The prices of fish oil and fish meal had not wholly recovered from their 
1921 slump, and only 6,800,000 pounds of herring were diverted for this purpose.
