We hypothesized that impaired ovarian function (e.g., reduced ovary size) in wild fish chronically exposed to bleached pulp mill effluents is related to an increased rate of apoptosis in ovarian follicle (granulosa and (or) theca) cells. In 1996, vitellogenic white sucker (Catostomus commersoni) collected downstream of a bleached kraft pulp mill had reduced ovary size associated with increases in ovarian cell apoptosis and stress protein (HSP70) expression when compared with fish collected from an upstream reference site. Fish sampling was repeated in 1998 following mill maintenance changes aimed at minimizing the discharge of process chemicals. In 1998, there were no differences in ovary size, ovarian cell apoptosis, or ovarian HSP70 levels between fish collected upstream and downstream of the mill. Based on the results of this and our previous work, we conclude that chronic stimulation of ovarian cell apoptosis by certain components of mill effluents may represent an important cellular mechanism responsible for reductions in ovary size, and potentially other integrated reproductive responses, in female fish exposed to pulp mill effluents.

Growth and reproductive capacity in perch (Percafluviatilia L.) and roach (Rutilusrutilus (L.)) were studied during 1983, 1984 and 1985 in a coastal area of the Bothnian Sea affected by bleached pulp mill effluents. Comparative investigations were made at a mill producing unbleached pulp. In perch exposed to bleachery effluents effects were observed on length increase rates, somatic condition factors and on gonad development. The fraction of fishes displaying inhibited gonadal recrudescence was high close to the mill, and the size of developing gonads was comparatively small. Growth was faster in exposed fishes, in young-of-the-year as well as in older fish. Effects on length growth could be distinguished as far back as in 1975. Energy storage, expressed as the condition factor, was highest in exposed fishes. The effect pattern was more diffuse in roach, but examples of reduced gonad growth were noted. In conclusion, these studies provided evidence for changes in the energy allocation system in fish exposed to a bleached pulp mill effluent.
