Abstract: While many studies have shown that pulp/paper mill effluents can influence fish reproduction, there are few leads for remedial strategies. To gain insights regarding solutions, effluents from nine mills were tested for effects on fish reproduction and characterized chemically. Most effluents affected fish reproduction, but the degree of the effects varied substantially. Effluents with the lowest overall organic content (measured as BOD and total gas chromatography peak areas of effluent sol- vent extracts), probably resulting from spill control and efficient biotreatment systems, caused the least effects.
