|Scientific Name:||Syngnathus carinatus (Gilbert, 1892)|
Siphostoma carinatum Gilbert, 1892
|Taxonomic Source(s):||Dawson, C.E. 1985. Indo-Pacific Pipefishes (Red Sea to the Americas). The Gulf Coast Research Laboratory Ocean Springs, Mississippi, USA.|
|Taxonomic Notes:||The Order for this Family has changed from Syngnathiformes to Gasterosteiformes (Nelson 2006)|
|Red List Category & Criteria:||Data Deficient ver 3.1|
|Contributor(s):||Acero, A. & Findley, L.|
This species is restricted to the upper Gulf of California. It is a shallow water species that occurs in estuarine habitats that are increasingly disturbed by coastal development and aquaculture. However, very little is known about the population status of this species and the impact of current threats. It is therefore assessed as Data Deficient.
|Previously published Red List assessments:|
|Range Description:||Syngnathus carinatus is endemic to the northern Gulf of California (Fritzsche 1980, Dawson 1985).|
Native:Mexico (Baja California, Sonora)
|FAO Marine Fishing Areas:|
Pacific – eastern central

|Population:||Syngnathus carinatus is not abundant. There have been no dedicated surveys or population estimates to date. Further research is needed in order to determine population size and trends in abundance for this species.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Syngnathus carinatus is found on sand substrata, estuaries, beaches, and soft substrata (L. Findley pers. comm. 2007). Little is known about its feeding, but it likely consumes prey similar to that of other pipefishes, including mysids, gammarid shrimps, and harpacticoid copepods (Kendrick and Hyndes 2005). They are ovoviviparous, and males brood the embryos beneath their tail prior to giving live birth (Breder and Rosen 1966, Dawson 1985). This species is found at depths to 36 m.|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Use and Trade:||This species has not been specifically identified in trade, but pipefishes in general are often targeted and/or caught as bycatch in shrimp trawls and traded for use in the aquarium trade, as curios, and for traditional medicines (Vincent et al. 2011). This species may be involved but levels of offtake are unknown.|
|Major Threat(s):||Coastal development such as marina construction and aquaculture development has caused much of the estuarine habitat of this species to be degraded (L. Findley pers. comm. 2007). In addition, the damming of the Colorado River and water divergence from other rivers has placed estuaries in the region at risk due to hypersaline conditions (Rowell et al. 2008, A. Cisneros-Montemayor pers. comm. 2016).|
|Conservation Actions:||This species occurs in at least one marine protected area with questionable enforcement (the Alto Golfo de California Biosphere Reserve; L. Findley pers. comm. 2007).|
