Description of morphological parameters of respiratory gill surface of gudgeon Gobio gobio (L.) from the diverse waters of Perm region

Morphological parameters of gudgeon gills of different types of Perm reservoirs were decrypted. A comparison of absolute and relative area of the gill surface of fish in ponds with different anthropogenic load was been. It was showed a rather high stability of the indices studied, as well as a large relative area of respiratory surface in fish from a flowing body of water.
