Stellate tadpole-goby Benthophilus stellatus (Sauvage, 1874) in the Cheboksary Reservoir

Abstract

Some meristic characteristics of the population of the stellate tadpole goby from the Cheboksary Reservoir are given for the first time. All studied specimens were sexually mature females of age 1+. In the fall, the stellate tadpole goby feeds exclusively on mollusks (% of occurrence): Lithoglyphus naticoides (85%), Dreissena sp. (6%), Valvata sp. (6%), and Bithynia sp. (3%).

Alien Species of Fish in the Littoral of Volga and Kama Reservoirs (Results of Complex Expeditions of IBIW RAS in 2005-2017)

“…DNA-barcoding of these fish [Kodukhova et al, 2016] did not confirm the idea that Volga's population of stellate tadpole goby is represented by Don River species B. durrelli [Boldyrev, Bogutskaya, 2007]. By now, stellate tadpole goby is regularly found in the reservoirs of the Lower and Middle Volga [Kasyanov, Klevakin, 2011;Shakirova et al, 2015], in the Cheboksary reservoir within the territory of Nizhniy Novgorod area (Klevakin et al, 2005), and a single adult specimen was caught in the Rybinsk Reservoir [Kodukhova et al, 2016].…”
