Abstract

This study was undertaken to determine the impact of a standard portable fish counting fence and associated biological studies on water quality in Campbellton River. Two counting fences have been installed annually in this river since 1993, one, for counting adults, located at 160 m and the other, and the other for counting smolts, at 300 m from the community water intake for the town of Campbellton. Water samples were collected during the summer of 2001, at sites above and below the smolt and adult counting fences and just prior to and after the counting fences were installed. These samples were analyzed for selected heavy metals and basic bacteria levels. Also, added to this study is data from selected historical water quality samples taken by Department of Fisheries and Oceans or the Department of Environment in 1972, 1987, 1990, 1992, 1993, 1994 and 2000. The results indicated that there was no effect on water quality from the introduction of the counting fences or from related biological studies carried out for the Campbellton River.
