The effect of the antibiotic chlortetracycline and the anthelmintic albendazole on morphological features, internal organs, alkaline phosphatase activity and protein content in the gills of two-year-old carp was studied. It was found that chlortetracycline and albendazole at the studied concentrations in water and short-term action do not affect the morphological features, behavior and internal organs, but change the alkaline phosphatase activity of the gills of two-year-old carp. The antibiotic chlortetracycline at concentrations of 1.10, 3.15, and 6.30 mg/dm3 of water and fish exposure for 72 h reduced the alkaline phosphatase activity of gills in carp of the first experimental group by 2.5 times, in the second – by 2.8 times and in the third – by 2.7 times regard the control; it did not affect the protein content in the gills, morphological features and internal organs of fish. We registered an increase in alkaline phosphatase activity of gills in two-year-old carp under effect of anthelmintic albendazole at at the concentration of 1.0 mg/dm3 by 28.2%, while albendazole concentration of 0.2 and 0.5 mg/dm3 did not affect the alkaline phosphatase activity as well as the level of protein in fish body. Our results indicate an important role of gill alkaline phosphatase in assessing the negative effects of antibiotics and water anthelmintics in freshwater fish.

Key words: freshwater fish, morphological features, respiratory organs, antibiotic, anthelmintic, protein.
