May for reproduction (at 6 °C); reaches sexual maturity at three years of age. The
largest and most tasty goby!
Population trends. Rather abundant, caught with stake nets and drag seines; 1989
landings on the Romanian littoral 23 t, on the Bulgarian littoral - 23 t; in Turkey 2101,
in Russia 810 t. Stocks endangered by periods of hypoxia following algal blooms,
when hundreds of dead specimens are thrown on the beaches. In August 1989,
massive numers of dead fish were recorded along the Romanian littoral.
Threats. Eutrophication and algal blooms followed by hypoxia.
Conservation measures taken. Construction of artificial reefs in the Dniester River
estuary strongly increased the local abundance of gobiids.
Conservation measures proposed. Mitigation of anthropogenic stress; building of
different types of artificial reefs; full protection in breeding seasons.
