"t" test of catch-per-unit-effort and 

 effort, rowboat fishery. Fishing Bridge dock, 19^0 and 19^1 



"t" 0.19U at 15 d.f. 0.989 at 15 d.f. 



In both cases the "t" values were not significant. It was thus con- 

 cluded that there was no significant difference in either the average 

 effort or catch-per-unit-effort between the 1950 and 1951 seasons. Any 

 difference in total catch could then be attributed to an increase or de- 

 crease in number of anglers and not to any change in availability of fish 

 to the fisherman. As shown in a graph of total hours of fishing by two- 

 week periods (fig. 3), the total hours of fishing for 1951 is higher than 

 for 1950. Because there is no significant difference in the average 

 effort rates, the total fishing hours is directly related to the number 

 of fishermen. We would thus expect the catch to be relatively larger for 

 1951. Although not as pronounced as is the amount of effort, the distri- 

 bution of the catch (fig. k) is generally higher, verifying the expectation. 



Guideboats s 



During the 1950 season, five guideboats operated from Fishing Bridge 

 dock. In 1951, however, only one guideboat operated from this dock, but 

 five operated from Lake Dock, less than one mile distant and immediately 

 in front of the Lake Hotel (fig, 1). Although not operating from the same 

 dock, the guideboats fished the sarae waters throughout the summer of 1951 

 and were therefore considered as one unit in this analysis. There was no 

 change in areas fished by guideboats from 1950 to 1951 even though there 

 was a change in location of docks. The data gathered from this unit are 

 summarized in table 5o
