Changes of the content of ammonia, total nitrogen and protein in organs and tissues of carp under the long-term impact of the heightened concentration of the allochthonous nitrogen have been investigated. It was stated that in the organisms of fish occur active processes directed to the fixation and excretion of the ammonia. It was marked that the most noticeable changes of physiological and biochemical parameters under the impact of mineral nitrogen occur in the blood plasma.
