Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Distinguished from Silurus glanis by the following unique characters: one pair of mental barbels; and anal fin with 66-75½ rays (Ref. 59043).
Inhabits lowland rivers and nutrient-rich lakes. Feeds at night mainly on fish. Also preys on crustaceans, gastropods, insects, amphibians and aquatic snakes. Spawns in pairs. Attains first sexual maturity at 2-3 years of age (Ref. 59043).
Males defend small territories at the spawning sites and construct nests made of plant materials. They dig shallow depressions or clean spawnng substrate, at 2-3 m depth. They guard nests until larvae emerge. Spawns in pairs. Eggs hatch in 5 days (Ref. 59043).
