Protective effect of weak pulsed magnetic fields on early ontogeny of tugun Coregonus tugun (Pallas) under conditions of chronic oil pollution

Protective effect of weak pulsed magnetic fields on early ontogeny of tugun Coregonus tugun... The state of internal organs in tugun larvae was analyzed histologically in the intact (control) group, the group treated with a water-soluble oil fraction (WSOF) in fivefold excess over the maximum allowable concentration, and the group exposed in a weak pulsed magnetic field at the stage of hatching, prior to treatment with WSOF. Larvae of the second group had severe pathologies of inner organs that caused 100% mortality before the age of 15 days, but no pathomorphological changes in the organs of larvae and juvenile fish of the third group were revealed for up to 40 days.

Abstract

The state of internal organs in tugun larvae was analyzed histologically in the intact (control) group, the group treated with a water-soluble oil fraction (WSOF) in fivefold excess over the maximum allowable concentration, and the group exposed in a weak pulsed magnetic field at the stage of hatching, prior to treatment with WSOF. Larvae of the second group had severe pathologies of inner organs that caused 100% mortality before the age of 15 days, but no pathomorphological changes in the organs of larvae and juvenile fish of the third group were revealed for up to 40 days. Probable causes of high resistance to the toxic agent in fish of the experimental group are discussed.
