چکیده
A new three-breed cross-hybrid of carp has been obtained in the fish farm «Kirya» Chuvash region (RF). comparative assessment fingerlings showed advantages cross over other crosses grown same (Sursky malokostny and Petrovsky) on a number indicators: weight, body length, indices high-spin, physical development. In youngsters cross, intensity hematopoiesis (erythropoiesis leukopoiesis) is higher than rest studied crosses. The content lysosomal cationic protein blood neutrophils at an optimal level indicates good state cellular immunity fish.
