COMMERCIAL FISHERIES. 



Upon our entrj' into the war, our fish packers responded to the 

 government's call for an increased production of food by greatly 

 increasing the output of the canneries. IMany new canneries were 

 built and nearly all were enlarged. Unfortunately, the large pack of 

 sardines and tuna intended for European trade was held in this country 

 for speculative purposes, with a consequent fall of prices and a great 

 loss to the packers. 



The biennial period has been one of readjustment. ]\lany canneries 

 ceased to operate because of the unsold stock in -hand. Several can- 

 neries failed financially, and practically all have had difficulty in sur- 

 viving the depression. The past year, however, has shown a rapid 

 recovery and there is hope that the industrj^ will again become stable. 

 However, the present rates of exchange are still a great handicap to 

 foreign trade. There is hope that with better times ahead, additional 

 fisheries Mill be developed. Our larger fisheries, with the exception of 

 the salmon, have only recently been developed, and a great future for 

 them is assured. 



Although the condition of the fisheries is of importance in our work, 

 the duty of the commercial fisheries department is to look out, pri- 

 marily, for the conservation of the fisheries and the safeguarding of 

 them against over-fishing. Following there will be found a report of 

 the investigations undertaken to secure dependable data as to the status 

 of the fisheries, data useful as a basis of legislation looking toward their 

 preservation. 

 _ Under the direction of Professor J. 0. Snyder of Stanford Univer- 

 sity, an investigation to ascertain additional information regarding 

 the life history and distribution of the king salmon has been begun. A 

 series of marking experiments instituted has made it possible to deter-
