Syngnathus abaster is a freshwater and estuarine pipefish species that inhabits coastal waters and lower reaches of rivers throughout the Caspian, Black, and Mediterranean Seas, the Atlantic coast of Europe to the Bay of Biscay, and several rivers in northern Europe and Russia. The species occupies a wide variety of habitats, and there are no known threats. Therefore S. abaster is listed as Least Concern.

Geographic Range [top]

Range Description:Syngnathus abaster inhabits coastal waters and lower reaches of rivers in the Caspian, Black and Mediterranean Sea basins, the Atlantic coast from Gibraltar to the southern Bay of Biscay; in the Danube reaching the Romanian-Hungarian border, and in the Dniepr reaching Kiev. The species has been introduced in reservoirs of the middle and lower Volga with mysids brought from the Don estuary, now spreading and already south of Moscow.

Habitat and Ecology [top]

Habitat and Ecology:Syngnathus abaster inhabits a wide range of marine, brackish- and fresh-water habitats, and is mostly associated with dense submerged vegetation but is also found on open mud bottom substrates (Kuiter 2000).

They live up to four years and spawn for the first time at one year. The spawning season occurs from April-October (Silva et al. 2006a). This species is ovoviviparous, and females lay eggs into a brood pouch on the ventral surface of the tail of males. Males fertilize the eggs as they enter the pouch. Eggs incubate in the male's brood pouch for about 20-25 days, followed by live birth (Silva et al. 2006b). This species is polygynandrous (Hubner et al. 2013). They likely feed on small invertebrates such as crustaceans, similar to other pipefish species (e.g., Garcia et al. 2005, Kendrick and Hyndes 2005). They reach a maximum length of 21 cm (Kuiter 2000).
Systems:Freshwater; Marine
Movement patterns:Unknown

Use and Trade [top]

Use and Trade: Although this species has not been directly identified in trade, pipefishes in general are often targeted and/or caught as bycatch and then traded for use in traditional medicine, as curios, and for the aquarium trade (Vincent et al. 2011). This species may be involved but it has not been recorded.

Threats [top]

Major Threat(s): There are no major threats known to be impacting this species.
