Abstract

Studies were conducted for 10-11 mo using biologically treated bleached kraft mill effluent at concentrations ranging from 0.5-2.0 mg.L-1 of effluent BOD5 (1.3-5.1% v/v) and for 42 mo at 0.5 BOD5 addition (1.5% v/v). Lesions or tissue changes observed in fish from both control and effluent-treated streams were of primary or secondary parasite-induced etiology, a condition typical of natural streams. Data corroborate the lack of effluent effects as determined from measurements of trout growth, survival, production, and reproduction. -from Authors
