摘要: 1. Carp were exposed to 280 ppm formalin. Haematocrit and plasma glucose lactic acid increased. In moribund fish, blood pH was remarkably lower protein 2. When formalin, heart rate (HR) respiration increased briefly, then decreased. 3. Some fish urine flow (UF) immediately maintained higher values for a while, followed by gradual decrease, others decreased UF consistently. stopped at 30 min or longer prior death. Urine osmotic pressure the 1st 2nd hour before stopped. 4. The relationship between UF, HR also discussed.
