Sociability / Life stage (?) | Not entered |
Reproductive frequency (?) | Iteroparous |
Reproductive type (?) | Sexual Comments: The dimorphism between the sexes (apart from during the breeding season) is not easily visible. The dorsal fins of males are slightly larger and closer to each other than in females. The ventral fins also differentiate the sexes as they are shorter and of different shape in males. Breeding males are much darker than females, sometimes almost black with distinct irregularly scattered bright bluish-green spots. Spots of the same colour, but arranged in even, horizontal rows are present on the dorsal and anal fins. Also in the breeding season males have inflated areas on the head. |

J.]., Germany: AULA-Verlag, 135-156 Comments: Amur sleeper is a predator with morphological features that enable hunting of a large variety of aquatic organisms with inclusion of relatively big prey items. |

Salinity tolerance range (?) | Venice system: 1. Limnetic [<0.5psu] 2. β-Oligohaline [0.5-3psu] References: Paavola M, Olenin S, Leppäkoski E (2005) Are invasive species most successful in habitats of low native species richness across European brackish water seas?

Habitat modifying ability potential (?) | Keystone species Comments: When evaluating the potential impact of this species on ecosystems it might be concluded that several taxonomic groups of native hydrofauna, both macroinvetebrates and vertebrates would be potentially affected by the presence of this new predator. |
