Histological and Electrophoretic Analysis of Carpathian barbel (Barbus carpathicus Cyprinidae) Skin and Mucus in Environmental Context

摘要

Natural environment monitoring and identification of river or lake water pollution plays an important role for human comfort and safety. Some fish, as water-living animals, are especially sensitive to any water quality changes. Fish skin forms a natural border between the water and internal organs of the animal’s body; therefore, the skin must be able to provide defense and resistance against any factors dangerous for the fish. Some seasonal changes can influence the skin morphology and physiology (mucus composition), blurring the assessment of the skin’s reaction to any contamination.
