Researches Concerning Reference Values Assessment of Serum Biochemical Parameters in some Fish Species from Acipenseridae, Cyprinidae, Esocidae and Salmonidae Family

Abstract

The purpose of this work was to assess reference values of serum biochemical indices (enzymes, metabolites and minerals) in some representative fish species belonging to Acipenseridae, Cyprinidae, Esocidae and Salmonidae family in order to establish a baseline data which will serve to monitoring nutritional-metabolic balance and healthy condition of these species from aquatic biocenosis or intensive exploitations. Serum samples were analyzed for glucose, total proteins, albumine, urea nitrogen, creatinine, uric acid, triglycerides, cholesterol, ALT, AST, GGT, alkaline phosphatase, amylase, total bilirubin, Ca, P, Mg, Fe, using a FullyVet automated chemical analyser. The obtained results were compared with those from other papers regarding serum biochemical profile of fresh water fish species. Serum biochemical reference intervals were as follows: glucose, 28.41±0.80–64.00±1.41 mgdL-1; total proteins, 2.78±0.21-4.05±0.20 gdL-1; albumine, 0.67±0.12–1.59±0.11 gdL-1; urea nitrogen, 12.16±0.78–18.30±0.27 mgdL-1; creatinine, 0.06±0.01–0.27±0.00 mgdL-1; uric acid, 1.00±0.00–1.66±0.09 mgdL-1; triglycerides, 46.00±1.29– 351.3±12.3 mgdL-1; cholesterol, 123.00±2.12–198.00±0.91±mgdL-1; ALT, 15.00±0.91–32.00±1.29 IU L-1; AST, 30.00±0.91–92.00±1.47 IU L-1; GGT, 4.00±0.00–6.33±0.46 IU L-1; alkaline phosphatase, 60.33±1.20–109.50±3.05 IU L-1; amylase, 28.08±0.93 – 36.00±0.91 IU L-1; total bilirubin, 0.00±0.00–0.03±0.00 mgdL-1; Ca, 7.63±0.40–12.36±0.50 mgdL-1; P, 11.83±0.35-30.48±0.26 mgdL-1; Mg, 1.80±0.14–3.88±0.21mgdL-1; Fe, 57.60±3.48–120.00± 1.08 mgdL-1. The wide intra- and interspecific variability of our data requires subsequent studies of the endo- and exogenous factors (living condition, season, age, gender, origin, breeding system, physiological and nutritional status, genetic of each individual, etc.) that can induce variations of the propound parameter.
