METHODS 



The first experiment was conducted on 26 April 

 and the second experiment during 6 and 7 June 

 1985. Pink salmon fry were captured in the Yakoun 

 River during 10-18 April using two inclined plane 

 traps with mouth openings of 1.1 m'^. The traps 

 were emptied each morning and the pink salmon 

 transferred by truck to several 1 m^ net pens at- 



tached to the research vessel Velella, anchored at 

 Marinelli Point (Fig. 1). 



All pink salmon were tagged and marked to allow 

 positive identification after they were released. Dur- 

 ing 15-18 April 6,000 pink salmon were anesthe- 

 tized with tricaine-methanesulfonate (MS-222) and 

 tagged with half-length binary-coded wire tags by 

 an experienced tagging crew. Proper placement of 

 each tag was confirmed by passing all fish through
