Analysis of interpopulation and interspecies morphological differences between Far Eastern redfins of the genus Tribolodon (Teleostei: Cyprinidae)

Resumo

The morphological variability in sympatric populations of the Far Eastern redfins Tribolodon brandti and T. hakonensis from bays of the Sea of Japan was studied by analyzing the standard set of measurements that is used for the description of cyprinid fishes. It has been established that the interpopulation morphological differences between individuals within each species exceed the differences between species. The main causes of intraand interspecies differences have been revealed.
