Title

EFFECTS OF STOCKING DENSITY ON CORTISOL LEVEL OF SIBERIAN STURGEON, ACIPENSER BAERII

Pages

  154-162

Abstract

 Siberian sturgeon (Acipenser baerii) has been imported to Iran as a valuable candidate for aquaculture purpose. Since the STOCKING DENSITY is considered as an important STRESSor in aquaculture, Hence this study was conducted to investigate the impacts of its stocking densities on chronic STRESS using the blood CORTISOL level. In total, 90 specimens with 342±30 g mean weight and 45.3±1 cm total length were stocked in three densities (6, 12 and 18 specimen/tank) pending 5 months rearing period. The results showed no significant interaction among density–time parameters and CORTISOL level (p > 0.05), whereas solely time showed a significant correlation with CORTISOL level (p < 0.05). The levels of CORTISOL in July, August, October and November were 4.68±1.84, 23.22±4.44, 3.98±1.66 and 11.8±2.53ng/ml respectively. Mean CORTISOL concentrations in low, moderate and high densities obtained 7.76±3.59, 12.94±2.78 and 10.76±3.72 ng/ml, respectively that was not observed significant changes in no treatments. Results of this study can suggest that Siberian sturgeon withstand STOCKING DENSITY norms which are used for Iranian sturgeons.
