Journal of Applied Ichthyology, 21:242-262. |
Sociability / Life stage (?) |
|
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. |
Developmental trait (?) | Spawning References: Bogutskaya NG, Naseka AM (2002) Perccottus glenii Dybowski, 1877. Freshwater Fishes of Russia. Zoological Institute RAS. http://www.zin.ru/Animalia/Pisces/eng/taxbase_e/species_e/perccottus/perccottus_e.htm |
Characteristic feeding method / Life stage (?) |
References (not structured): Miller P, Vasil'eva ED (2003) Perccottus glenii Dybowsky 1877. In: The Freshwater Fishes of Europe. Vol. 8/I Mugilidae, Atherinidae, Atherionopsidae, Blennidae, Odontobutidae, Gobiidae 1 [ed. by Miller, P. 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. |
Mobility / Life stage (?) |
|
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. |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Anthropogenic chemical compounds References: Petrovskiy, A. B., Ksenofontov, D. A., Kozhanova, E. I., Reshetnikov, A. N. 2024. Concentrations of Trace Elements (Mn, Zn, Cu, Fe, Ni, Co, and Cd) in Invasive Fish Perccottus glenii in Water Bodies of Moscow. Russian Journal of Biological Invasions, 15(1), pp. 112-118. |
Known human health impact? | Not known Comments: Negative effects on human health unknown. |
Known economic impact? | Known References: Verreycken, H. 2015. Risk analysis of the Amur sleeper Perccottus glenii. Risk analysis report of non-native organisms in Belgium, Rapporten van het Instituut voor Natuur-en Bosonderzoek, 27. Comments: In aquaculture facilities, juveniles of Amur sleeper are competitors for food to many species of gobies, ruffe, perch, minnows, loaches; to common bitterling Rhodeus amarus and other fish species for chironomid larvae and crustaceans and among reared fishes to yearlings of carp. |
Known measurable environmental impact? | Known References: Verreycken, H. 2015. Risk analysis of the Amur sleeper Perccottus glenii. Risk analysis report of non-native organisms in Belgium, Rapporten van het Instituut voor Natuur-en Bosonderzoek, 27. Comments: The environmental impacts of Amur sleeper in are through competition for food and predation but also possibly through pathogen pollution and disruption of trophic interactions. |
