Small and abundant but understudied ribbed sculpin Triglops pingelii (Cottidae, Teleostei) from the Kara Sea (Siberian Arctic): distribution, biology, and comparison with congeners
The features of the spatial and vertical distributions, and size-age and size-sex structures of the ribbed sculpin Triglops pingelii of the Kara Sea are presented. In September 2019, this species was recorded at depths from 18 to 235 m at a bottom temperature from -1.5 to +1.6 degrees C. The densest...

In September 2019, this species was recorded at depths from 18 to 235 m at a bottom temperature from -1.5 to +1.6 degrees C. The densest concentrations were recorded northeastward of the Yamal Peninsula, at the outlet of the Gulf of Ob at a depth of 18-21 m and a bottom temperature from -1.5 to -1.0 degrees C. Individuals with a length of 46-126 mm and a body weight of 0.35-15.60 g aged 1+ to 4+ years were recorded in trawl catches. However, fish with a length of 51-90 mm and a body weight < 6 g aged 1+-2+ years dominated. Among fish > 71 mm long, the proportion of females increased sharply, reaching 100% with a length of 120 mm.
