Ecology: Habitat :
Large and medium size lowland rivers , backwaters and well vegetated lakes . Spawns in shallow, warm and well vegetated riverine habitats without current .

Biology :
Lives up to 80 years in the wild. Spawns for the first time at 2-3 years and 1-2 kg . Spawns in April-June, in northern areas until August, when temperature reaches about 20°C. In spawning grounds , males defend small territories and build nests of plant material , dig shallow depressions or clean spawning substrate such as willow (Salix) roots . Nests are defended by males until larvae emerge . Spawns in pairs. During spawning act, the male embraces the female. Eggs hatch in 2-3 days and larvae remain in nest until yolk sack is absorbed (2-4 days). A nocturnal predator , feeding near bottom and in water column . Very sensitive to extra-aquatic sounds . Head sensory canal system allows to track the wakes [a trail of hydrodynamic and chemical signatures left by a swimming fish] of prey up to 10 seconds old over distances up to 55 times the length of the prey. Larvae and juveniles benthic and negatively phototactic, feeding on a wide variety of invertebrates and fish. Adults feed on fish and other aquatic vertebrates .[2].
