UTILIZATION OF THE FISH WASTE OF THE PACIFIC OCEAN. 17 



In general, it is sufficient to designate the region under considera- 

 tion, as the various centers of the industry are characterized by 

 certain grades. Thus, in the Bristol Bay region of Alaska the pack 

 consists of 94 per cent red fish, or sockeyes. In southeastern Alaska, 

 between Icy Straits and Dixon Entrance, the total pack contains 

 about 1 per cent of " reds." In many canneries the proportion of 

 red fish put up is negligible. In the Puget Sound region the com- 

 position of the pack varies with the year. In years of a large run of 

 sockeyes, as in 1913, the pack may contain as much as 65 per cent of 

 the red salmon. In other years, as in 1912, it may comprise only 

 45 per cent of sockeyes. In the three seasons preceding the last, 

 1910, 1911, and 1912, the average composition of the packs on Puget 

 Sound was 22 per cent " reds." On the Columbia River the pack 

 is composed almost entirely of red fish. While the figure which 

 represents the exact proportions of waste from the red fish is not 

 known, it can be said with a fair degree of accuracy that the waste 

 from humpbacks is from 40 per cent to 50 per cent of the round 



weight. 



Thus, to fill a case of 48 1-pound cans, from 17 to 19 5- 



pound salmon are required. On this basis, a round weight of from 

 85 to 95 pounds is reduced to 48 pounds, representing a waste of from 

 37 to 47 pounds per case. For the sake of conservativeness in this 

 discussion, 40 pounds per case has been taken to represent the waste 

 from humpbacks and 30 pounds per case that from the " reds." On 

 the basis of the foregoing figures representing "the total pack of 

 salmon, taking 30 pounds per case as representing the loss from red 

 salmon and 40 pounds per case from the others, the amount of can- 

 nery waste produced by centers may be estimated. Likewise the 

 value has been computed on the basis of $15 per ton, the value fixed 

 by present commercial operations. The following table gives the 

 amount of cannery waste and its value :
