past few years. However, a study reveals that this increase has 

 been occasioned ahnost entirely by larger catches of a few species of 

 fish used for canning, which are termed "cannery " fish. These are 

 pilchards (sardines) and tunas, the production of which amounted 

 to about 176,000,000 pounds in 1918, 81,000,000 in 1921, and 413,- 

 000,000 in 1927. On the other hand, the catch of "market" fish, 

 which includes all species of tinfishes, although showing fluctuation, 

 has remained in the neighborhood of 50,000,000 to 60,000,000 pounds 

 in recent years. During this time about 80 per cent of the catch 

 has consisted of cannery fish.
