Assessment of blood chemistry reference values for cultured sturgeon hybrids (Acipenser naccarii female × Acipenser baerii male)

摘要: Summary Blood chemistry profiles of cultured sturgeon hybrids Acipenser naccarii female × Acipenser baerii male were assessed in order to acquire basic data for evaluating fish health status on-farm. Sixty healthy (11.0 ± 3.2 Kg weight; 117.8 ± 8.6 cm total length) randomly captured from 600 m3 concrete tanks and sampled April June. Blood samples analyzed the following 22 biochemical parameters using standard clinical methods: cortisol, glucose, lactate, non esterified fatty acids, triglycerides, cholesterol, albumin, creatinine, urea, bilirubin, protein, aspartate aminotransferase, alanine alkaline phosphatase, creatine phosphokinase, lactate dehydrogenase, calcium, phosphorus, magnesium, sodium, potassium chloride. Biochemical values found be consistent with parental species A. naccarii. Cortisol, CK, LDH magnesium significantly affected by sampling time differences are probably related sexual maturation fish. analyses afforded an accurate evaluation sturgeons’ status, also providing information on their reproductive conditions. Evidence resulting cortisol indicated that pre-sampling operations, including capture confinement these large-sized fish, must carefully managed minimize handling stress. This study provides knowledge blood hybrid A. naccarii × A. baerii results corroborate validity test panel performed physiological functions sturgeons. Reference identified purpose welfare
