Abstract

1. Rainbow trout were anesthetized with MS-222 (Sandoz) or methylpentynol and catheterized. Urine was collected at selected intervals up to 48 hr. 2. Effects of MS-222 anesthesia on urine flow and composition were isolated from the stress of catheterization by re-anesthetizing the fish 18 to 20 hr post catheterization. 3. Urine output patterns were similar following MS-222 or methylpentynol anesthesia and catheterization. Highest urine flows were measured 4 to 8 hr post treatment. The highest urine output after re-anesthetization with MS-222 was observed 2 to 4 hr post-anesthesia. 4. Highest concentrations of Na2+, K+, Ca2+, Cl- and inorganic PO4 in the urine were measured in the first 2 hr after anesthesia and catheterization. 5. Flow rates and chemical composition of urine indicate that "normal" renal function is re-established 12 to 24 hr post-treatment.
