Of the fish affected by the electric current, only salmonids 

 and burbot were netted and placed in a holding net. Most 

 captured fish were anaesthetized wit 4-amino benzoate (if 

 needed) , identified to species, measured to the nearest mm total 

 length (TL) , and released. Some of the captured YOY grayling 

 were weighed to the nearest gram with an Ohaus Lume-o-gram 

 electronic balance for condition factor calculation. The 

 equation 



K = (VI) (100.000) W = weight in grams 

 L 3 L = length in mm. 



was used for condition factor calculation. 



Select brook trout, rainbow trout, and burbot had stomach 

 contents removed through gastric levage before being released. 



Stomach Content Analysis 



Gastric levage was performed on brook trout (n=177) , rainbow 

 trout (n=5) , and burbot (n=15) as described by Light, et al., 

 (1983) to secure stomach contents for later analysis. The 

 contents were flushed into storage bottles using Light's levage 

 device, and preserved in a 5% formalin solution or an ethanol 

 solution. Several fish (n=10) were sacrificed to determine the 

 efficiency of gastric levage in this study. Stomachs were 

 removed and preserved to later identify any remaining contents.
