VREELAND ET AL.: HOMING BEHAVIOR OF MARKED COHO SALMON 



for their cooperation and assistance in conducting 

 this study. Our appreciation is extended to the 

 owners of the Astoria Yacht Club for the use of 

 their boat launch ramp. We are indebted to the 

 hatchery superintendents and personnel at 

 Klaskanine, Big Creek, Elokomin, Grays River, 

 and Little White Salmon hatcheries for their as- 

 sistance in examining coho returns for our marked 

 fish. We would also like to thank the fishery 

 biologists with the Fish Commission of Oregon 

 who provided us with Columbia River commercial 

 gill-net catch data. Particular thanks go to Steve 

 K. Olhausen, who did much of the fishery sampling 

 at Youngs Bay.
