Abstract The effects of salinity on oxygen consumption and ammonia excretion were studied in juvenile crayfish Procambarus clarkii with initial body weight of (1.82±0.21) g and body length of (3.13±0.30) cm at the salinity of 0, 2, 4, 6, 8, 10, and 12 at 25 ℃. The minimal oxygen consumption and ammonia excretion were found at a salinity of 2, indicating that the iso-osmotic point of the juveniles was around 2. The rates of oxygen consumption and ammonia excretion increased with increase in salinity. Turkey HSD test revealed that there were no significant differences of oxygen consumption and ammonia excretion in the juveniles exposed to salinity of 0, 2, 4, and 6.
