Size-age and sex population structure have been studied for the aboriginal stellate tadpole-goby Benthophilus stellatus and Don tadpole-goby B. durrelli in the Don River basin. The females of Don tadpole-goby mature at a body length of about 35 mm, stellate tadpole-goby females, at 50 mm. Most breeders of Don tadpole-goby (~74%) are characterized b...

... for the Sea of Azov, are slightly larger. It was previously believed that all spawners die after spawning in the second year of life (Ilyin, 1927a(Ilyin, , 1927b). In the Tsimlyansk Reservoir, most spawners die as one-year-old I, but single specimens of one-year-olds II and twoyear-olds I (2.) are noted. Thus, one-year-old II males SL 83-94 mm (Fig. 3b) were noted along with YOY ( Fig. 3a) caught at the end of December 2015, judging by the clear winter ring on otoliths, while rare specimens SL > 90 mm, caught in the spring, were twoyear-olds I (Fig. 1). Individuals of both sexes older than two years have also been noted for Berg tadpolegoby B. leobergius in the southern part of the ...
