Go to Species Summary

Eudontomyzon mariae   (Berg, 1931)
Family:	Petromyzontidae (Lampreys) , subfamily: Petromyzontinae			picture (Eumar_u0.jpg) by Levin, B.
Order:	Petromyzontiformes  (lampreys)
Class:	Cephalaspidomorphi (lampreys)
FishBase name:	Ukrainian brook lamprey
Max. size:	22.2 cm TL (male/unsexed; Ref. 12283); max. reported age: 8 years
Environment:	demersal; potamodromous
Climate:	temperate; 57°N - 41°N
Global Importance:	fisheries: of no interest; bait: usually
Resilience:	Low, minimum population doubling time 4.5 - 14 years (K=0.35-0.50; tm=8)
Distribution:	Europe: Drainages of the Baltic Sea (Odra, Vistula, Neman), northern Black Sea (Sava, Drava, Danube [except Tisza, Timis, and Cerna rivers], Prut, Dnieper, Dniester, Don, Kuban, and in rivers of Georgia from Bzyb' in south to Chorokhi in north), Aegean Sea (Vardar), and Caspian Sea (Volga - Sura River) (Ref. 58030). One record in the upper Morava system (Czechia) (Ref. 59043).
Diagnosis:	Dorsal spines (total): 0-0; Dorsal soft rays (total): 0-0; Anal spines: 0-0; Anal soft rays: 0-0. WIth 62-73 trunk myomeres; trunk mottled in live ammocoetes older than 2.5 years. The caudal fin is dark grey to black in adults and ammocoetes older than 1.5 years. The shape of the caudal fin is spade-like.
Biology:	Non-parasitic freshwater lamprey; inhabits the mountain and foothill zones of watercourses containing clear water with a strong current and gravel-sand substrate. The ammocoetes larvae live in detritus-rich sand-mud substrates in areas of weak current, frequently beneath overhanging banks. Ammocoetes feed on diatoms and detritus; adults don't feed. Ammocoetes used as live bait (Ref. 12283). Preyed on by the chub (Leuciscus cephalus) and other predators in the period of their spawning (beginning of May to beginning of June). This species spawns on gravel and sand substrates, also possibly over hard white clay (Ref. 58030)
Threatened:	, (Ref. 36508)
Dangerous:	harmless
