A summary of Atlantic salmon (Salmo salar) and other aquatic species captured during electrofishing surveys on rivers within the outer Bay of Fundy region in 2009 / by Ross A. Jones, Yvette C. Cyr and... : Fs97-6/3526E-PDF

"An expanded electrofishing survey was conducted in 2009 on the rivers within Outer Bay of Fundy (OBoF) region in Salmon Fishing Area (SFA) 23 to assist a review of Atlantic Salmon (Salmo salar) populations in Eastern Canada by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). The survey was designed to sample the smaller, less studied, tributaries in order to examine the distribution and densities of various freshwater fish species, particularly Atlantic Salmon. Results from these new sites (n=84) were compared to the regularly sampled index sites (n=51) from the more 40 tributaries or rivers sampled within the outer region of SFA23. Although Atlantic Salmon juveniles of at least one age class were captured at more than half these sites surveyed, the overall densities were well below those of healthy self sustaining populations. The highest mean densities of juvenile salmon were observed on two index rivers; the Keswick (17.8 fish per 100 m²) and Shikatehawk (25.3 fish per 100 m²) rivers. The distribution and densities of other species varied amongst the different geographic areas. American eel catches were larger and more prevalent in the sites located downriver of the Mactaquac Hydroelectric Dam than the sites sampled upriver of the dam. Non-native species, such as Smallmouth Bass and Rainbow Trout were captured more frequently at the sites upriver of Mactaquac Dam"--Abstract, page vii.
