Zosterisessor ophiocephalus is restricted to the Mediterranean Sea, the Black Sea and the Sea of Azov. There is no population information for this species, although it is thought to be locally abundant. There are no known widespread threats. Therefore, Zosterisessor ophiocephalus is listed as Least Concern.

Geographic Range [top]

Range Description:Zosterisessor ophiocephalus is only known from the Mediterranean Sea, the Black Sea, and the Sea of Azov. In the Mediterranean, the species is known from southwestern France, from Sardinia and northern Corsica, along the western coast of Italy, Sicily (Relini and Lanteri 2010), the northern parts of the eastern coast of the Adriatic (Kovačić et al. 2012), from the Aegean, and Mediterranean Turkish coasts (Bilecenoglu et al. 2002). It is also known from Tunisia (Bradai et al. 2004) and western Libya. It has been recorded from most of the Black Sea coastal areas, with fewer records from eastern parts.
Countries occurrence:
Bulgaria; Croatia; France (Corsica, France (mainland)); Greece (East Aegean Is., Greece (mainland), Kriti); Italy (Italy (mainland), Sardegna, Sicilia); Libya; Monaco; Romania; Russian Federation (European Russia, South European Russia); Slovenia; Tunisia; Turkey (Turkey-in-Asia, Turkey-in-Europe); Ukraine (Krym, Ukraine (main part))

Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Zosterisessor ophiocephalus is a benthic species living inshore in marine and brackish waters, estuaries and lagoons and on mud and eel-grass meadows. Its habitat is more abundant in the eastern part of its distribution. The primary prey items for Z. ophiocephalus are small fish and larger crustacean (Miller 1986). Individuals of Z. ophiocephalus are sexually mature at two to three years, and the maximum lifespan is five years (Miller 1986). It is iteroparous, with females producing more than one batch of eggs within the breeding season (Franco et al. 2002). In the Mediterranean, the maximum recorded size is 21.0 cm TL and the length at maturity for females ranges from 9.8 to 12.2 cm TL and for males is 13.5 cm TL (Tsikliras and Stergiou 2014).
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: This species is harvested for food in some parts of its range. The species has commercial importance in parts of its range, including in the Black Sea and in Sivash (Berg 1965). Miller (1986) documents tissue contaminants (PCBs, DDT etc.) and heavy metal concentrations in fish from Greek and Italian habitats, which may affect consumers.

Threats [top]

Major Threat(s): The species habitat may be impacted locally but there are no known widespread threats.

Conservation Actions [top]

Conservation Actions: No species-specific conservation measures are in place or needed for Z. ophiocephalus. However, it likely occurs in marine protected areas. It was assessed globally as Data Deficient in 1996 and as Least Concern in the Mediterranean (Abdul Malak et al. 2011, IUCN 2011).
