employment to 27,482 persons, represented an investment of $70,- 
986,221, and yielded products valued at $41,492,124. 
A detailed account of the extent and condition of the Alaska fish- 
eries in 1920 and of the activities of the Bureau under the laws and 
regulations for the protection of the fisheries is embodied im the 
annual report of the Alaska service for that year.* 
ENFORCEMENT OF FISHERY LAWS AND REGULATIONS. 
During the fishing season of 1920 the Bureau had in service for 
patrol purposes 13 vessels, and the same number was available in 
1921. For the 1921 season the persons engaged in connection with 
the enforcement of laws and regulations numbered 63, of whom 23 
were regular and 40 were temporary employees. 
A number of violations of the fishery laws were detected and suc- 
cessful prosecutions were made in the local courts. The Bureau is 
doing its utmost, however, to prevent violations by maintaining 
watchmen or guards at the mouths of salmon streams throughout 
the fishing season. In some instances the stream guards, being 
equipped with small power boats, are able to look after two or three 
streams so close together that their absence from any one stream 
will not be so protracted as to permit illegal fishing within the 
stream or inside the protected area at its mouth. It is the policy 
to discourage and prevent violations, for thereby not only are 
the expense and annoyance of prosecution avoided but, what is of 
ereater importance, the salmon which would have been killed through 
such illegal fishing are permitted to proceed to the spawning grounds, 
The extension of the stream-watchmen system will be made as fast 
as funds are available and shculd soon embrace every important 
salmon stream. 
Attention has been devoted during the year to the erection of addi- 
tional markers near the mouths of salmon streams to give fishermen 
notice as to the limits of the areas in which salmon fishing is pro- 
hibited. Suitably inseribed cloth notices have been posted con- 
spicuously, and thus far upwards of 200 of the more important 
salmon streams have been marked.
