title: Serum electrolyte and nonelectrolyte status in freshwater juvenile Persian sturgeon Acipenser persicus.
abstract: Status of serum electrolyte and nonelectrolyte variables can be used for managing sturgeon species cultured in freshwater or living in seawater. The aim of the present study was to evaluate serum biochemical variables in clinically healthy juvenile Persian sturgeon Acipenser persicus cultured in freshwater. Serum samples from 11 females and 10 males were analyzed, and levels (mean +/- SD) of the following variables were compared between sexes: glucose (Glc; 5.58 +/- 1.25 mmol/L for females and 8.56 +/- 1.80 mmol/L for males), total cholesterol (TC; 2.50 +/- 0.45 and 2.40 +/- 0.65 mmol/L), triglyceride (TG; 7.13 +/- 2.68 and 5.14 +/- 1.27 mmol/L), blood urea nitrogen (BUN; 1.28 +/- 0.2 and 1.01 +/- 0.2 mmol/L), total protein (TOP; 55.84 +/- 8.77 and 41.44 +/- 8.62 g/L), inorganic phosphate (P(i); 6.19 +/- 1.02 and 5.23 +/- 0.49 mmol/L), calcium (Ca; 2.80 +/- 0.43 and 2.63 +/- 0.32 mmol/L), magnesium (Mg; 0.9 +/- 0.23 and 0.99 +/- 0.22 mmol/L), sodium (Na; 152.80 +/- 13.81 and 156.38 +/- 12.67 mmol/L), potassium (K; 2.64 +/- 0.58 and 2.27 +/- 0.39 mmol/L), and chloride (Cl; 143 +/- 13.85 and 151.67 +/- 21.08 mmol/L). There were no differences in TC, Ca, Mg, Na, K, or Cl between sexes. The Glc value was lower in female Persian sturgeon than in males, whereas the values of TG, BUN, TOP, and P(i) were higher in females than in males. Freshwater adaptation may affect serum ion concentrations in juvenile Persian sturgeon.
