Abstract


The major modification of those parameters go to apparition of the biological and physico-chemical imbalance of water environment who produce disturbance to normal way of vital function, that respond through the primary physiological modification (endocrine) follow by secondary physiological modification (hormonal), with direct influence over the growing parameters and the pathological condition. The rearing experiments were lasting 60 days and have been achieved on young beluga sturgeon (Huso huso) in two different locations, with two different recirculating pilot systems. Was analyzed the main physico-chemical parameters of sturgeon culture, obtaining 23 - 25°C temperature, 4 – 5 mg/l dissolved oxygen, 7,6 upH pH, 0,02 – 0,23 mg/l ammonia, 0,13 – 0,17 mg/l ammonium, 0,09 – 0,45 mg/l nitrite and 10,55 – 72,06 mg/l nitrate.
