Abstract
The study gives a description of histopathological analysis of internal organs of Caspian sar-delle (sprat) (Clupeonella cultriventris caspia). There were found some orbicular dimensionaltu-mors in its liver and spleen that conform to signs of metastasizing carcinomas (insulomas). Such tumors have been identified at anchovy sprat earlier. The histologic analysis has revealed circulatory embarrassment and vascular changes, hemolysis, tissues edema, redundant development of connective tissue. The polymorphism of both hepatocyte and their cores has been found in the liver. The presence of the modified structural elements (insulomas) in a spleen is an evidence of tumor metastasizing. It is determined that the morphological changes in internal organs of Cas-pian sardelle are similar to the violations found in internal organs of anchovy sprat.
