Channel catfish, Ictalurus punctatus Rafinesque, injected intraperitoneally with 2-methyl-quinoline sulphate (QdSO4) or 3-trifluoromethyl-4-nitrophenol (TFM) eliminate most of the dose of these compounds by extra-renal routes. Patterns of renal excretion of Na+, K+, Ca2+, Mg2+, and Cl- (pEq kg-1 h-1) appeared to be associated with the 'stress' of the urine collection technique rather than with the elimination of either compound. Concentrations of Na+, K+, Ca2+, Mg2+, and Cl- (mEq/1) were determined in urine, plasma and gall bladder bile.
