The next step of analysis was to determine the portion of the 

 whole represented by the fishermen sampled. To accomplish this a 

 representative distribution of fishing intensity throughout the day 

 was set up, using complete efforts recorded in census sampling (see 

 discussion on page 9 ), The complete efforts were plotted graphically 

 as shown in the hypothetical example in Table 3o In this case a person 

 making a census of this fishjng area once each hour during the census 

 day (see definition on page 7) from 6 A.Fo to 7 P.Mo would have recorded 

 98 fishermen. The census covered a period of 14 hours, thus an average 

 of 7 fishermen were present per hour.. Since 25 individuals were involved 

 it can be determined that 28 percent of the individual fishermen were 

 present per hour (7 / 25 X 100 = 28) (see Appendix Tables I C, II C, 

 III C, and IV C) . 



Because no two census samples of this survey were taken at the 

 same location during any one day, the sane individuals were not counted 

 twice. Thus the total number of fishermen recorded could be considered 

 as the average for the area or, in the above example, they would represent 

 28 percent of the total number of individual fishermen in the area covered 

 by the census. The number of fishermen recorded could thus be adjusted to 

 obtain the total number of fishermen at census stations. 



The regular airplane surveys previously described revealed the per- 

 centage of fishermen at census stations (see Appendix Tables I D and II D) • 

 The number of fishermen at census stations was adjusted accordingly to 

 obtain the total number of fishenaen in the area surveyed. 



Total number of hours of fishing during the period of analysis -jifas 

 determined by multiplying total number of fishermen by the average length 

 in hours of a completed fishing effort for that period. The total catch 

 was obtained by multiplying total number of hours by the catch per hour 

 of the period of analysis (see Appendix Tables II E, III D and IV D) • 



King Salmon Fishery 



Creel census sampling of the king salmon fishery revealed that 

 diu-ing the period from September 1 through December 31, 1947, approxi- 

 mately 3,300 salmon weighing 62,400 pounds were taken in 83,200 hours 

 of angling by 23,400 fishing efforts between Middle Creek and Chico 

 Creek. During the following fishing season, May 1, 1948 - February 28, 

 1949, approximately 8,000 salmon weighing 136,200 pounds were taken in 

 171,300 hours of angling by 43,800 fishing efforts from the same area. 



The sports fishery for king salmon ranked first in importance in 

 the number of fi shing efforts and hours expended during the 1948-49 

 season when censuses were mede of all fisheries concurrently. The 

 salmon catch was second in number but was first in estimated poundage.
