The catch per hour for trout increased or decreased with the 

 catch in most instances as discussed previously, This appears to 

 "be a coincidence as it has been shown that there vras a stronger 

 relationship between the number of fishing efforts and the catch. 

 This characteristic seemed to offset any adverse relationship be- 

 tween the catch per hour and the catche The catch per hour for 

 trout did not appear to follow a pattern of the abxindance of trout. 

 The greatest abundance of trout is believed to oucur from October 

 through February when the heaviest steelhead spawning migrations 

 take place. The catch per hour, however, did not show significant 

 or sustained increase during this period as compared to other months 

 of the fishing season when mostly resident rainbows or river resident 

 steelhead were taken o 



The catch per hour for trout fell from 0.086 (12 hours per fish) 

 during the period from December through Februarj' 1947-48 to 0.076 

 (13 hours per fish) fish per hour in the same months of 1948-49. The 

 reason for the reduction in catch per hour is not known but it is not 

 believed to be a definite indication of a reduced population in the 

 latter periodo 



Striped Bass Fishery 



During the months May through September, 1948, there were approximately 

 600 striped bass taken in 14,300 hours of angling by 5,100 fishing efforts 

 between Red Bluff and Chico Creek. Striped bass fishing above Red Bluff in 

 1948 was virtually absent. 



The striped bass fishery ranked third in importftnce in the number of 

 fishing efforts and hours fished and fourth in number of fish taken. 



The monthly catch of striped bass seemed to vary directly with their 

 abundance in the Upper Sacramento River area. The striped bass migrate 

 into the upper river starting early in May, reaching an apparent peak 

 in July and subsiding through September as they move downstream. The 

 monthly catch follows this same pattern (Table 6). 



Tne number of fishing efforts, hours per fishing effort and catch 

 per hour vary directly with the catch. Thus it appears that all factors 

 relating to the striped bass fishery are dependent upon the abundance of 

 the fisho 



Although a few people fish for striped bass froia October through 

 April, no catches have been recorded for those months.
