Abstract

It is the first time, when genetic diversity and the common kilka population structure were investigated throughout the areal. Data about the species condition at the Upper Volga basins were updated accordingly to modern condition. Physiological and ecological adaptations to northern water basins were evaluated. Significance of interaction between some loci and the most important abiotic environmental factors at the selection was demonstrated. The results suggest that the common kilka Clupeonella cultriventris (Nordmann, 1840) is presented by uniform set of population throughout the areal. The successive expansion of the species through the cascade of the Volga's water reservoirs can be explained by complex of genetic and biochemical adaptation for sweet water habitat. It was supposed that the sweet water populations originated from Saratov's backwaters sweet water population. Seasonal fluctuations of abiotic and biotic environmental factors have significant influence on genotype distribution at the newly formed population. This book is intended for use by ichthyologists, ecologists, environmental protection and management of natural resources specialists. In Russian.

36. Finding of topmouth gudgeon Pseudorasbora parva(Temminck et Schlegel) (Actinopterygii: Cyprinidae) in the Brahmaputra River basin (Tibetan Plateau, China)

Author

Makhrov, A., Artamonova, V., and Karabanov, D.

Abstract

Two individuals of Pseudorasbora parvawere caught in a small irrigating canal flowing into the upstream reach of the Brahmaputra River. The taxonomic status of these specimens was confirmed by morphological analysis and analysis of the mitochondrial cytochrome coxidase subunit I (COI) sequences (known as barcoding).

37. Topmouth gudgeon Pseudorasbora parva(Cyprinidae)—A new species in the ichthyofauna of Azerbaijan

Author

Karabanov, D., Kodukhova, Yu., and Mustafayev, N.

Abstract

The paper presents the morphological and biological description of the topmouth gudgeon Pseudorasbora parva(Temminck et Schlegel, 1846) (Actinopterygii: Cyprinidae) from the water bodies of Azerbaijan. Low variability of morphological features in the studied populations is shown. The maximum age of the fish is 6+, the age of most adult fish is 3+ and 4+ and the immature fish are of age 0+ and 1+. The absolute fecundity ranges from 430 to 8690 eggs with an average value of 1940 eggs. It is known that the topmouth gudgeon has spread in the territory of western (Akstafa and Kazakh regions) and southern Azerbaijan (Lenkoran region).
