Deoember of 1948, July was the hottest month of 1948 and this factor, 

 coupled vfith an abundance of salmon in the upper river area where most 

 trout were taken, reduced the amount of fishing effort and in turn the 

 catch* Trout fishermen were drawn to salmon spawning areas during 

 October, 1948, where trout are believed to be more vulnerable as they 

 feed on salmon ep;gs lost in the spawning process. Thus, the heavy 

 fishing pressure and catches in October are not reflected in the lower 

 catch per hour. Unusually severe weather in December recuded the number 

 of trout fishermen and catch regardless of the increased availability. 



During the comparable periods, December through February, in 1947- 

 48 and 1948-49, tht catch fell from some 3,800 to 1,600 trout (Table 2). 

 A slight reduction in the catch per hour in the latter year influenced 

 the catch. A marked reduction in the length of the fishing effort and 

 nimber of fishing efforts, due to the unusually cold vdnter of 1948-49, 

 probably contributed most to the reduced catch. 



The number of rainbow-eteelhead fishing efforts varied directly 

 with the catch in all except one of the thirteen months of analysis. 

 This exception occurred in February when fishing pressure increased 

 along with somewhat improved weather conditions, but the catch per 

 hour dropped enough to prevent an increased catch for the month. The 

 number of fishing efforts seemed to be most dependent on conditions 

 other than the abundance and availability of the trout. Fotir peaks 

 in fishing effort occurred during the 1948-49 fishing season. The 

 greatest peak occurred in June when most anglers seemed to take their 

 first lengthy fishing vacations m 1948 | a minor peak came in August, 

 which was the heaviest tourist month (trout fishing parties travel 

 farther in August than any other month - Table 8)} a second major peak 

 came in October during the period of heaviest salmon fishing and an 

 increase in salmon spawning activity, both of which attract many trout 

 fishermen; the last and least peak in fishing pressure came in February 

 and was influenced by the season's close at the end of the month and more 

 favorable fishing weather during the month. If fishing intensity was 

 influenced by the availability of trout as shown by the catch per hour, 

 major peaks would have occurred in June, Augua,t and January. 



The number of trout fishing efforts during December through 

 January decreased from some 10,900 in 1947-48 to 6,400 in 1948-49. 

 The reduction was a direct result of the colder weather during the 

 latter season. 



TUne length of the fishing effort for trout seemed to have little 

 relationship to the availability of fish or the catch. This factor 

 seemed to depend mostly on weather and fishing conditions. During 

 the three months of comparison of the 1947-48 and 1948-49 fishing 

 seasons, the length of the fishing effort fell from 4.23 hours to 

 3.10 hours. This can be attributed to colder weather during the 

 latter period.
