BULLETIN OF THE UNITED STATES FISH COMMISSION. 
fisheries exist for this species alone in various localities. It is put up in pickle and , 
sold in San Francisco. The demand there, however, is limited. \ 
No diminution of the supiily of this trout has been observed. There is great i 
destruction of this fisb at Karluk in the seining for Red Salmon, where thousands of j 
Dolly Vardens are taken and left lying unused on the beach. Something should be ( 
slone to prevent this waste of good fish. Bears destroy a great many of these trout 
and water birds consume immense numbers of the young. At sea sharks, porpoises, ! 
seals, and sea-lions prey extensively upon the adults.
