Etymology: Pseudaspius: Name from Greek 'pseudo-' for 'false' and 'aspius' which refers to the European genus Aspius (synonym of Leuciscus); originated from Greek 'aspis' meaning 'poisonous snake' like 'Egyptian cobra' (Peyman and Jalal, 2011).. More on author: Dybowski.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; demersal; anadromous (Ref. 51243); depth range - m (Ref. ), usually - m (Ref. ). Temperate; 10°C - 24°C (Ref. 13614); 55°N - 34°N, 89°E - 148°E

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 1441); max. published weight: 1.5 kg (Ref. 56557); max. reported age: 10 years (Ref. 56527)
Spawns from May to September. Spent adults descend to sea after spawning. Immature specimens occur in the mouths of rivers the whole year round; the young descend to the sea upon attaining a length of 7-9 cm (Ref. 1441).
