Short description आकृति विज्ञान | मौरफोमैटरिक्स

Diagnosed from congeners in Black and Caspian Sea basins by having straight or slightly arched mouth, 9½ branched dorsal rays, 50-62 scales on lateral line, usually 10½ branched anal rays, and large eye, diameter 50-65% of interorbital distance (Ref. 59043).

जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Occurs in lowland and piedmont rivers with moderate to strong current and in reservoirs. Commonly found in river main courses in rapids, sandy shallows and river curves. Larvae and juveniles with superior mouth prey on small invertebrates. After 3-4 months, juveniles measuring about 3-3.5 cm SL change to adult feeding mode and graze benthic diatoms and detritus from hard substrate in habitats with strong currents. Breeds on gravel or rock bottom in shallow riffles of larger rivers or in smaller tributaries with moderate to strong current. Most of the year in the middle and upper stretches of rivers, moves to lower stretches or to larger tributaries during winter. Deposits sticky eggs which adhere to gravel. (Ref. 59043).
