Channel catfish, Ictalurus punctatus Rafinesque, injected intraperitoneally with 2‐methyl‐quinoline sulphate (QdSO 4 ) 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 + , Ca 2+ , Mg 2+ , and Cl − (ρEq 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 + , Ca 2+ , Mg 2+ , and Cl − (mEq/1) were determined in urine, plasma and gall bladder bile.
