Many authors noticed the actuality of fish hematological parameters usage as indices of anthropogenic influence. Blood system reflects the reaction of the body on the action of different ecological factors. The problem of heavy metals influence on hematological parameters of silver cap (Hypopthalmichtys molitrix) needs to be investigated. The aim of the work was studying of ecotoxical Plumbum and Cadmium influence on hematological indices of silver carp (Hypopthalmichtys molitrix) during the period exposition. The results of the investigations concerning the influence of Plumbum and Cadmium on some hematological indices of silver carp (Hypopthalmichtys molitrix) for 12 days exposition up to the action of these heavy metals are given in this article. Experimental part was realized at the Lviv research station of Institute of fisheries NAAS (Lviv oblast, Horodok region, Velykyi Lyubin). Experimental groups contained 10 two-years individuals each. Fish were adopted to laboratory conditions for 5 days under the temperature 19 ± 2ºС, рН = 7.3 ± 0.2, oxygen content 7–8 mg/l. Blood parameters were measured on the sixth and twelfth days at the control group and groups which were under the influence on the level of 2 and 5 MPC of the appropriate metal. It was proved that the influence of Plumbum and Cadmium causes the lowering of erythrocytes number, hemoglobin and corpuscular volume: the effect becomes stronger when he concentration increases and in time. The effect from intoxication by Cadmium comes faster than by Plumbum.
