Mediterranean regional assessment: Data Deficient (DD)

This species was previously considered endemic to the Mediterranean Sea (Bombace 1993), however the fish is now known to also be found in the Black Sea, and there are unconfirmed records from the Atlantic. In the Mediterranean Sea the species has a scattered known distribution from the west coast of Italy to the Sea of Marmara. This species occupies nearshore and estuarine habitats that are under severe pressure from pollution and coastal development (see reviews in Lotze et al. 2011, Perez-Ruzafa et al. 2011). There is limited knowledge about the species' population and distribution within its range in order to assess this species' level of extinction risk. It is therefore listed as Data Deficient.

Geographic Range [top]

Range Description:In the Mediterranean Sea the species is known from scattered records from the Tyrrhenian Sea off the west coast of Italy, the Adriatic Sea (Franzoi et al. 1993), the Greek seas (Ondrias 1971, Papaconstantinou 1988), and the Sea of Marmora. Further range studies need to be carried out to determine whether these are disjunct populations or if the species occurs throughout the northern Mediterranean.

This species has previously been noted off the Mediterranean coast of France (Louisy 2002), however this appears to have been a misidentification (Hablutzel and Wilson 2011, P. Louisy pers. comm. 2014), as does a record from the Atlantic coast of Portugal (GBIF 2016). There are confirmed records of the species from the Black Sea coast of Bulgaria (Kuiter 2000).

Population [top]

Population:There is a documented population along the Italian coast, where individuals are found in high abundance (Franzoi et al. 1993), and this species was found at mean annual abundances (number of individuals per beach seine haul) of between 0.14–0.59 in the Venice Lagoon in 2002 (Franco et al. 2006). Individuals have also been found in the Greek seas (Ondrias 1971, Papaconstantinou 1988), but population sizes are unknown.
Current Population Trend:Unknown

Habitat and Ecology [top]

Habitat and Ecology:Syngnathus taenionotus is a demersal species which is found in brackish coastal lagoons, mostly amongst detritus or vegetation over shallow muddy substrata (Dawson 1986), in areas with macroalgae (Franzoi et al. 1993), seagrass beds, sparsely vegetated habitats, bare sand habitats, mudflats or salt marshes (Franco et al. 2006). It is an estuarine resident (Franco et al. 2006).

It is ovoviviparous i.e., the male broods the embryos in a pouch found under his tail (Breder and Rosen 1966).
Continuing decline in area, extent and/or quality of habitat:Yes
Congregatory:Congregatory (and dispersive)

Use and Trade [top]

Use and Trade:

The species is not traded or exploited commercially.

Threats [top]

Major Threat(s): Syngnathus taenionotus is threatened by the degradation of shallow-water habitats. Habitat loss is caused by land reclamation and coastal development, and habitat quality has decreased as a result of sedimentation, pollution and eutrophication (see reviews in Lotze et al. 2011, Perez-Ruzafa et al. 2011).

Conservation Actions [top]

Conservation Actions: No specific conservation measures are in place for this species, although its range overlaps with several marine protected areas. Further research and monitoring should be conducted to determine the wider distribution, population size, trends and threats to the species while the habitat trends need to be monitored for further declines.
