Abstract
The oxygen consumption and ammonia excretion of Kashgarian loach Triplophysa yarkandensis (Day, 1877) under different body weights were studied in laboratory condition. The specific oxygen consumption rate (SOC) and specific ammonia excretion rate (SAE) decreased with increasing body weight, while the total oxygen consumption rate and total ammonia excretion rate increased with increasing body weight. The relationship between specific oxygen consumption rate and body weight (x) can be expressed as SOC = -0.246Ln(x) + 0.8395 (R2 = 0.965), and the relationship between specific ammonia excretion rate and body weight can be expressed as SAE = -0.1252x +2.5558 (R2 = 0.9326). Results from the present study provide fundamental information on the routine metabolic requirements of T.yarkandensis. Such information may enhance the effectiveness of intensive rearing procedures in T.yarkandensis, and the success of live fish transportation.
