Abstract

Stellate tabpole-goby Benthophilus stellatus (Sauvage, 1874) is one of 5 representatives of the goby family (Gobiidae) in Belarus, discovered in 2011 in the Dnieper River. Until now, this species within Belarus is practically haven’t been studied and is of interest for the study as a new species in the freshwater watercourses. Standard ichthyological methods of trapping and methods of processing the material have been used in the study. A total of 39 morphometric characteristics are investigated, however, the comparison with the specimens from the natural habitat was carried out by individual indicators using a two-sample t-test for independent samples (tst). The analysis of stellate tabpole-goby plastic characteristics from the Belarusian section of the Dnieper River is presented for a first time and the meristic characteristics data of the species on this section of the river is supplemented. There were significant differences on 3 meristic and 11 plastic features from the individuals of the stellate tabpole-goby from the Kakhovka reservoir (Ukraine, the lower reaches of the Dnieper River).
