Responses of white sucker (Catostomus commersoni) populations to changes in pulp mill effluent discharges.

Abstract: The impacts of pulp mill effluents on white sucker (Catostomus commersoni) have been studied at Jackfish Bay, Lake Superior, Canada since the late 1980s. The site receives effluent from a large pulp mill which is the only source of contamination in the area. Impacts on sexual maturity, gonad size, secondary sexual characteristics and circulating steroids hormone levels evident in the early years of the studies were evaluated after the mill ceased pulp production and effluent release, in 2005 and 2006. Sampling evaluated their performance relative to the previous 17 years of data. The addition of secondary treatment and chlorine substitution at the mill has shown improvements in some parameters like liver and gonad size. Reproductive parameters showed further improvement during the mill shutdown period and after the mill reopened in September 2006. Results showed that males may recover quicker than females and that some effects of the effluent are still remaining at the exposure site.
