Etymology: Neogobius: Greek, neos = new + Latin, gobius = gudgeon (Ref. 45335). More on author: Pallas.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; brackish; benthopelagic. Temperate; 4°C - 20°C (Ref. 2059); 56°N - 36°N, 25°E - 54°E
Eurasia: Azov and Black Sea basins. Invasive in rivers of northern Black Sea basin, recorded in 1997 from middle Vistula (Poland), reaching from Dniepr via a navigation canal. In Danube upriver to Hungary, in Dniepr up to Belurus. Introduced in Lake Balaton, Hungary around 1970.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm SL male/unsexed; (Ref. 59043); max. reported age: 5 years (Ref. 59043)
soft rays: 12 - 17. This species is distinguished from its congeners entering freshwater in the Black Sea basin by the following characters: first branched ray of second dorsal about twice as long as penultimate ray; completely scaled nape; pelvic-disc fraenum with small rounded lobes and the length is less than 1/6 of width at base; pelvic disc reaching 90-100% of distance between its origin and anus; scales in midlateral series 55-61 + 2-4; posterior part of first dorsal without black spot (Ref. 59043).
Occurs in inshore habitats, estuaries and brackish- and fresh-water lagoons and lakes; large to medium sized rivers and streams; on sand or mud bottom. It is one of the most abundant fish in lowland rivers. This species lives up to 5 years; spawns for the first time at 2 years; spawning season in April to July, locally until September, when temperature is above 13°C; females may repeat spawning during a season. Males with body completely black with yellow fin margins during the spawning season; these excavate nests under any kind of hard substrate and guard eggs until hatching; with adhesive eggs deposited on stones, shells and aquatic plants. Feeds on a variety of invertebrates, especially molluscs (Ref.59043).
Deposits oval eggs on stones. Male guards the eggs for 3-4 days (Ref.26211).Males have completely black body with yellow fin margins during spawning season. (Ref.59043).
