Effects of Different Intensities of Magnetic Fields on Sterlet, Acipenser ruthenus: Physiological and Biochemical Responses

To study of magnetic fields effects on physiological, biochemical and growth factors of Sterlet, Acipenser ruthenus , different intensities of magnetic fields ( 5, 15 and 25 mT) was used. In this research, sampling of sturgeons that affected by magnetized water was done after 1 and 2 months. So, blood sampling and biometry was carried out in two steps. Based on the statistical analysis, stress parameters did not show any significant differences ( p> 0.05) in control and treatment groups but there was significant difference in some biochemical factors like triglycerides level ( p<0.05). Also, there was significant difference in final weight and obesity ratio between control and treatment groups (p<0.05). Based on our study, magnetized water could be effective on physiological parameters and growth factors in sturgeons , so, these data are useful in aquaculture and fish farming.
