THE WATER QUALITY MONITORING IN THE RECIRCULATING SYSTEMS FOR INTENSIVE STURGEON CULTURE
Keywords:
recirculating system, water quality, sturgeon, sturgeon culture, beluga sturgeonAbstract
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.
