Alaska fisheeies and Jb'ue iNbusTMEs, 1911. 63 



The Revilla Reduction Works began business the hitter part of 

 1910, but it was found difficult to secure a sufficient suppl}' of shark 

 and dogfish livers to operate the piant, and the business was aban- 

 doned late in 1911. It is the intention to convert the establishment 

 into a canuer}^ for the preparation of special fish products. Mr. W. H. 

 Royden operated the large house-scow Elliott, wliich he moved from 

 place to place, and prepared oil from the livers of sharks and dog- 

 fish, incidentally handling such salmon and halibut as were required 

 for bait or were taken on the shark Unes. 



The Tyee Co., which is the only company in Alaska engaged in 

 what is called "shore whaling," has a permanent station at Tyee, in 

 southeast Alaska. As the station is situated some distance from the 

 ocean it was found inconvenient to operate. Tliis season the oil- 

 making macliinery was placed aboard a large barge and during the 

 first half of the season whaling was carried on in the neighborhood of 

 Kodiak Island, the catch cut up aboard tliis barge, and the oil tried 

 out. No attempt was made to prepare fertilizer as in previous 

 years. Later in the season the floating station was towed to south- 

 east Alaska and operated there. 



THE TROUT FISHERY. 



The State of Washington liaving removed its restrictions upon the 

 importation and sale of fresh Alaska Dolly Varden trout 10 or more 

 inches in length, a few fishermen made small shipments tliis year, 

 and it is probable that the industry will ultimately grow to one of 

 considerable magnitude. At present there is no special fishery for 

 tliis fish and the catch made is in connection with that of other 

 species. 



At the present time the waters of Alaska teem with trout, particu- 

 larly the Dolly Varden trout. They are so numerous that they 

 doubtless do great damage to the salmon by devouring enormous; 

 numbers of the eggs and fry of these more valuable fishes. Under the 

 conditions now obtaining tlieir destruction, like that of the dogfish, 

 may be looked upon as an advantage to the general fishery interests 

 in Alaska. 



There are five species of trout known from Alaska, namely, steel- 

 head, Dolly Varden or salmon trout, cuttliroat, rainbow, and lake. 

 At present the steelhead is put to the most varied uses, being mar- 

 keted fresh, frozen, pickled, and canned. The other species are all 

 marketed fresh.
