Summary The large Amu‐Darya shovelnose sturgeon Pseudoscaphirhynchus kaufmanni is a freshwater species presented by native normal and dwarf form in the Amu‐Darya River. Immunoelectrophoretic assay for serum protein antigens of the large Amu‐Darya shovelnose sturgeon detected ontogenetic variation when fishes of various sizes, sex, and gonad maturity were studied. A comparison between the development of shovelnose antigens with sturgeon species of the genus Acipenser showed similarities. These similarities are revealed by non‐synchronous formation of different serum protein antigens comprising both transferrin components. The βA‐globulin, a main and dominant antigen of adult fish, is developed much later then other antigens in shovelnose as well as in another sturgeon species. Normal and dwarf forms of the shovelnose transferrin development are distinct. Serum protein antigens in normal shovelnose form in a like manner similar to sturgeons of the genus Acipenser . Full maturation of dwarf females of smaller size is accompanied by alterations of their physiological system related to transferrin function and synthesis for one of the transferrin components is reduced.
