12 U. S. BUREAU OF FISHERIES 



The following chartered boats were used in fisheries patrol : Valkyrie, 

 Helen Hinton, Helen F, Lady Luck, and Bear in southeastern Alaska; 

 Stanley, Pilot, and Prospector on Copper River and Prince William 

 Sound; Coyote on Cook Inlet; and Auk in the Port Moller district. 



In connection with the regular patrol of the Yukon-Kuskokwim 

 district, transportation was afforded Dr. Ale§ Hrdlicka, curator of 

 the division of physical anthropology of the Smithsonian Institution, 

 Washington, D. C, who w^as a passenger on the Coot on its trip down 

 the Yukon from Nenana as far as the head of Portage Slough from May 

 19 to May 31 , and thereafter on the launch Marie S on the Kuskokwim 

 River. Doctor Hrdlicka remained in the district until the middle of 

 July, making investigations at old native villages between Stony 

 River and the mouth of the Kuskokwim in connection with his 

 anthropological studies. 



AERIAL PATROL 



As in the previous year, seaplanes were chartered from a commercial 

 company in 1930 and used at intervals, chiefly in southeastern Alaska, 

 to supplement the regular patrol of the fishing grounds by vessels and 

 launches. Because of the mountainous character of the country 

 and the fact that it is cut into many inlets and channels where fishing 

 operations are carried on, the use of aircraft as an auxiliary patrol is 

 of marked advantage in preventing or detecting violations of the 

 fishery regulations. As an example of the possibilities along this line 

 it may be cited that in a single day's flying in southeast Alaska in the 

 summer of 1930 a warden of the bureau covered more than 1,000 miles 

 of fishing grounds in various inlets and straits, making landings 

 from time to time at places where the view from aloft indicated the 

 possibility that fish traps were not properly closed during the weekly 

 period when fishing is prohibited. In addition to the fisheries patrol 

 service, a number of flights were made in connection with general 

 supervisory work and observations of the spawning grounds in certain 

 sections at the close of the fishing season. 



COMPLAINTS AND PROSECUTIONS 



Four salmon traps in southeastern Alaska were seized for illegal 

 fishing in 1930. A trap at Point Hepburn that belonged to Alaska 

 Pacific Salmon Corporation and one on Etolin Island belonging to 

 Columbia River Packers Association were found not properly closed 

 during a weekly closed period and fines of $400 and $500, respectively, 

 were imposed in the court of the local United States commissioner. 

 The Lincoln Fisheries (Inc.) was fined $1,100 for not closing its trap 

 on Sitklan Island at the end of the commercial fishing season. A 

 case was brought against the Clarence Strait Salmon Co. for operating 

 a trap at a distance of less than 1 statute mile from another trap, but 

 when it was called for trial the defendants failed to appear. Therefore 

 judgment was taken by default and the trap will be sold by the United 

 States marshal. 



In southeastern Alaska, also, the operators of four trolling boats 

 were apprehended for fishing during weekly closed periods. A fine of 

 $40 in the case of the Hazel T-1116 and fines of $25 each in the case 

 of the T-810 and T-1209 were imposed when complaints were brought 

 before the commissioner's court. Libel proceedings were filed against
