MUSCLE TISSUE OF FISH AS A BIOMARKER OF ECOLOGICAL STATUS OF RIVERS
Abstract
We report the histopathological status of muscle tissue in carp and goldfish, living in the Aras (Araks) and Arpachay rivers of the Nakhichevan Autonomous Republic. The selected biomarker tissue was histologically studied after staining the obtained sections with haematoxylin and eosin. Organization of muscle tissue of the fish caught in the Aras river was characterized by a slight change. Thus, the common carp exhibited winding of fibers, splitting of passing fibers, their damage and loss; the silver crucian carp - weak splitting of passing fibers, their loss and miopatya. The fish caught in the Arpachay river was characterized by the following changes: the common carp exhibited splitting of muscle fibers, their loss, regeneration, miopatya and winding; the silver crucian carp - the loss of muscle fibers, their splitting and winding. Based on the data obtained, we have drawn the conclusion that the environmental situation in the Aras river is relatively better than that in the Arpachay river.
