Impact of Low-Level Sampling Stress on Interpretation of Physiological Responses of White Sucker Exposed to Effluent from a Bleached Kraft Pulp Mill

In this study the authors evaluated the effects of handling and confinement stress on a number of biochemical parameters in prespawning male white sucker collected from a bleached kraft mill effluent (BKME) exposed and a reference site. There were no effects of site or stress level on plasma cholesterol or glutamic oxalacetic transaminase activity; all other parameters were affected by either sampling stress or overnight confinement. Unstressed …
