Optimal starvation time before blood sampling to get baseline data on several blood biochemical parameters in Amur sturgeon, Acipenser schrenckii

Abstract

This study tested the hypothesis that different starvation time for fish before blood sampling can influence the result of plasma biochemical analysis. Glucose (GLU), total cholesterol (CHOL), triglyceride (TGL) and total protein (TP) in the plasma of juvenile Amur sturgeon (Acipenser schrenckii) were measured after different starvation duration (0, 0.5, 1, 2 and 3 days). Starvation time had a significant influence on plasma GLU, CHOL, TGL and TP concentrations (P < 0.05). Plasma GLU and TP concentrations were unpredictably variable with duration of starvation. Plasma TGL and CHOL concentrations after 3 days starvation were significantly higher than that in fish starved for 0, 0.5, or 1 day, and no significant difference was found among fish starved for 0, 0.5, or 1 day. In order to get baseline value for these blood parameters, juvenile Amur sturgeon should be starved for 1 day.
