FISHERY INDUSTRIES OF THE UNITED STATES, 1929 761 



10 per cent; mackerel, 9 per cent; cod, haddock, haddock fillets, hake, 

 and pollock, 9 per cent; whiting, 7 per cent; and sea herring, 7 per 

 cent. Considerable quantities of shellfish, squid, croaker, butterfish, 

 and lake herring also were frozen. Frozen squid and sea herring 

 are marketed primarily for bait, although quantities of each are 

 used for human consumption. 



The above does not represent the entire amount of ground fish 

 frozen during 1929, for it must be borne in mind that the above 

 figures are obtained mainly from public freezing plants that report 

 their operations to the Government. During late years an increasing 

 number of privately owned establishments have been preparing 

 frozen package fishery products, and many of these did not begin 

 reporting their activities to the Government until late in the fall of 

 1929. However, an idea of the production of frozen package fish

 and Alaska, 1929. Salmon includes steelhead trout; sea herring in- 

 cludes alewives and bluebacks; cisco includes bluefin, blackfln, and chub 



may be gained from the review of the package fish trade in 1929, 

 which appears on pages — and — of this report. In brief, according 

 to this, the frozen pack of packaged fisherv products in 1929 amounted 

 to 21,849,120 pounds, valued at $3,920,688. This is an increase of 

 71 per cent when compared with the volume of these products packed 

 in 1928. 



Among the important species, by volume, frozen in 1929, that of 

 frozen ground fish increased 130 per cent over the production of this 

 group in 1928. That of sea herring increased 37 per cent, and halibut 

 12 per cent. The pack of other important species fared less well, for, 

 that of mackerel decreased 2 per cent; chinook salmon, 12 per cent; 

 silver salmon, 20 per cent; and whiting, 16 per cent. Some of the 

 minor species show increases of 50 to over 100 per cent. On the whole 

 there were greater quantities of the various salt-water species frozen 

 in 1929 than in the preceding year, and lesser quantities of the fresh- 

 water species.
