•^ive sur^reys were made in all„ By the time of the fourth survey, three 

 days after the tagging^ at least 80 percent of the fish vjere settled and 

 spawiing. Between the fourth and fifth survej'-s flood conditions had damaged 

 the trap, permitting the passage of more fish from beloWj and making further 

 obsenrations difficult,, Results are summarized in Table 1. 



It had been planned to raaice daily surveys after August 19j however, 

 weather conditions on Brooks Lake made it impossible to return to the creek 

 until the 25th, at which time the washout of the trap was discovered. The 

 creek was surveyed notwithstanding^ the search revealing totals of 95 tagged 

 and 699 untagged fish. 



Results of the four earlier surveys are fairly significantj however. 

 As can be seen from Table 1^ there was little disparity in movement or 

 selection of spawning area. In additionj close scrutiny by the observers 

 revealed no noticeable difference in vigor, or inability to find a mate, 

 between the two classes. Selection of mates seemed indiscriminate. 



Some of the fish were examined after natural death for degree of 

 spawning. Of four female and one male tagged fish examined, all were totally 

 spawned. Of Ik female and 6 male untagged salmon examined^ 10 females and 

 7 males were totally spawned, and U females and 1 male were partially spawned. 



A statistical treatment of the survey tabulations yielded Chi-square 

 values of 2,082. ii.9285 1.596 and 0.307, with values for ? of approximately 

 .70j, .50^ o90j and .95 for the first through the fourth survey respectively, 

 indicating a high degree of homogeneity in the data. 



While the experiment indicates that^ on streams of the character and 

 size, of Hidden Creek, tagging' has little effect on the subsequent life of 

 the fish, it should be borne in mind that the same results might not obtain 

 where longer distances and more time were involved, vdth possible tag loss, 

 differential orientation, and modified physiological reactions induced by 

 tags and the tagging operation.
