Marine Ecological Journal| Summary: | Intraspecific differentiation of the sprat Sprattus sprattus phalericus (Risso) was studied in the western part of the Black Sea. The set of intraspecific formations of different rank was selected on the base of the spatial distribution of eggs, larvae, juveniles and adult fishes; migratory behavior, biological specificity, presence of natural isolating mechanisms, etc. Two forms - «Rumanian» and «Crimean», which corresponding to requirements for population as elementary evolution unit, were selected. The ecological condition of the populations was described and some factors of were selected. The ecological condition of the populations was described and some factors of their formation were considered, also some management measures were proposed. |
