title: The physiological responses of the Caspian kutum (Rutilus frisii kutum) fry to the static magnetic fields with different intensities during acute and subacute exposures.
abstract: In recent years, the application of new technologies producing magnetic fields has widely increased in the aquatic environment. In this study, the effects of variable static magnetic fields on metabolic and immune parameters of the Caspian kutum fry were investigated. The Caspian kutum fry (n=220, body weight 1.78±0.11 g) was exposed to static magnetic fields with different intensities (2.5, 5.0, 7.5 mT) induced by electrical power supply during acute (one week) and subacute (3 weeks) periods. The results showed an increment in the quantity of ALT and AST enzymes (metabolic parameters) with increasing magnetic fields intensities in subacute and acute exposures (p<0.05). The lysozyme level, an immune parameter, showed a significant decrease, especially at intensities higher than 2.5 mT during subacute and acute exposures (p<0.05). It seems that low-intensity static magnetic fields can effect on the metabolism and immunity of the Caspian kutum fry as valuable commercial species.
