Species Diversity of the Family Cyprinidae in the Middle and Southern Caspian Sea
Abstract
The species diversity of the Cyprinidae family distributed in the Middle and Southern Caspian Sea is of particular importance for the conservation of the ichthyological biodiversity of the region. The research has revealed that several genera and species of the Cyprinidae family are widely distributed in this area. Among them, kutum (Rutilus frisii kutum), common carp (Cyprinus carpio), bream (Abramis brama orientalis), crucian carp (Carassius carassius), roach (Rutilus rutilus caspicus), and other representatives are dominant. The formation of species composition is significantly influenced by ecological factors such as water temperature, salinity, food resources, and anthropogenic impacts. In particular, industrial pollution, regulation of water resources, and fishing pressure have led to a decline in the population density of several species. Nevertheless, some adaptive species have managed to preserve their ranges by adjusting to new environmental conditions. The research results indicate that in order to conserve the biodiversity of cyprinids in the Middle and Southern Caspian Sea, it is essential to conduct modern ecological monitoring, restore natural spawning grounds, and apply scientifically based methods in fish stock management.
