Popis: Mortality rates were calculated in perch populations exposed to a Bothnian pulp mill effluent. The studies were made in 1983 and 1985 and comparisons were made with reference material collected at Aland. By catch-curve analysis and studies of age-distributions, it was shown that the mortality rates were higher in the exposed stock.
