Growth performance, hematological and serum biochemical parameters of juvenile Persian sturgeon (Acipenser persicus) fed with white button mushroom (Agaricus bisporus) powder

This study aimed to evaluate the effect of diets containing the white-button mushroom powder (WBMP) on growth performance and some hematological and biochemical indices of juvenile Persian sturgeon (Acipenser persicus). For this purpose, one hundred fifty-three juvenile of Persian sturgeon (47.78 ± 0.39 g) were distributed into nine experimental fish culture tanks with a total volume of 500 liters, filled with 300 liters of water. The fish were fed with diets containing 0.5% white-button mushroom powder (T1), 1% white-button mushroom powder (T2) and 0% white-button mushroom powder (control) as experimental diets for eight weeks. At the end of ‎the experimental period, no significant differences were observed in growth and feed‏ ‏utilization parameters between treatment and compare to the control diet (p>0.05). ‎Hematological parameter such as number of white blood cells was significantly ‎lower in the fish fed with the diet containing 1% WBMP compared to the control diet (p<0.05). The neutrophil percentage was significantly ‎higher in the fish fed with the diet containing 0.5 % WBMP compared to the control diet (p<0.05) as well. MCV, MCH, RBC, Hb, Hct, MCHC, lymphocyte, and monocytes were not different among the treatments (p>0.05). WBMP supplementation significantly increased serum glucose and cortisol in T1 and T2 (p<0.05). The current study results reveal that supplementation of diet with 0.5 and 1% WBMP causes negative effects on some blood and stress indices in juvenile Persian sturgeon. It seems that more studies are needed to determine the role of WBMP in sturgeon health and nutrition.
