2018Teleosts and elasmobranchs are the lowest vertebrates that possess adaptive immunity akin to mammalian ones. However, the fish immune system is different from that of mammals, that is, a lack of bone marrow, lymph nodes and germinal center. Their immune system is also characterized by the fact that their surface is covered by live cells with mucus in ...

Myoglobin polymorphism in the pollan (Osteichthyes: Coregoninae)
Animal Blood Groups and Biochemical Genetics, 1975SummaryThree electrophoretically separable phenotypes of heart and lateral line muscle myoglobin were found in the Irish pollan (Coregonus pollan). This polymorphism appears to be under the control of two co‐dominant alleles. The allele frequencies were found to be virtually identical in samples from two lakes which have probably been isolated since ...

Perea fluvialilis aucl. from the Pleistocene Eastern Europe (Likhvin) is identified with P. lepidosoma of the Miocene Western Siberia. Together with recent P. schrenkii of Balkhash lake they are assigned to the subgenus Dengizperca. Recent Euro-Asiatic and North-American perches are suggested to belong to the genus Perea s. str.

The presence and features of epithelium structures on surface of head and on scales, shape and structure of the scale plates in fish of the genus Barbus are shown to be species-specific. Based on scale structure the genus Barbus is proposed to be divided into three species groups: 1 ??? B. barbus, B. tauricus, B. kubanicus, B.
