On the Pacific coast, industrial 

 advancement and its demands upon 

 water for power lias discouraged 

 and will further discourage the nat- 

 ural reproduction of salmon. The 

 need for the hatcheiT-reared sal- 

 mon to overcome, at least in part, 

 the manmade deterrents to natural 

 reproduction is becoming ever more 

 apparent. 



The conservation of the salmon 

 resource is a public responsibility 

 and, as such, is of concern to the 

 agencies of the State and Federal 

 govermnents. In the Territory of 

 Alaska, tlie United States Fish and 

 AVikllife Service is charged with 

 jurisdiction over the fishery; in the 

 coastal States, the salmon fisheries 

 are regulated by the States and con- 

 servation activities are undertaken 

 by both the Service and the States. 

 It is not possible for a private indi- 



vidual or a group to control the 

 catch of salmon resulting from nat- 

 ural or artificial reproduction in a 

 given stream. This is true because 

 the catch is from public waters, ei- 

 ther the open ocean or the mouth of 

 the stream. However, in years past 

 some packers of salmon have under- 

 taken to improve salmon runs by as- 

 sistance to natural reproduction and 

 through artificial propagation. 

 Probably the earliest such eftort was 

 by Hume (1893). 



This publication describes briefly 

 the species of Pacific salmon and 

 their characteristics, reviews jjres- 

 ent-day methods of the artificial 

 propagation of the Pacific salmon, 

 outlines the human factors endan- 

 gering the maintenance of the fish- 

 ery, and explains the role of the 

 hatchery in the attempt to maintain 

 the fisheries at their highest possible 

 level.
