Syngnathus auliscus is a widespread Eastern Pacific pipefish that inhabits shallow waters with vegetation. There are no known major threats to this species, and no current indication of significant population decline from coastal development within its range. It is listed as Least Concern.
|Previously published Red List assessments:|
|Range Description:||This species is endemic to the Eastern Pacific region, and is found from Southern California, USA and the Gulf of California, Mexico to northern Peru (Fritzsche 1980, Dawson 1985).|
Native:Colombia; Costa Rica; Ecuador; El Salvador; Guatemala; Honduras; Mexico; Nicaragua; Panama; Peru; United States
|FAO Marine Fishing Areas:|
Pacific – southeast; Pacific – eastern central

|Population:||To date there have been no dedicated surveys or population estimates for S. auliscus. Further research is needed in order to determine population size and trends in abundance for this species.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This demersal species is usually found among vegetation in bays and estuaries, and occasionally among floating Sargassum species (Dawson 1985). Little is known about its feeding habits, but it likely consumes small benthic and/or planktonic crustaceans such as mysids, harpacticoid copepods, and gammarid shrimp like other pipefishes do (Kendrick and Hyndes 2005, Garcia et al. 2005). They are ovoviviparous, and the males brood embryos beneath their tail prior to giving live birth (Breder and Rosen 1966, Dawson 1985).|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Use and Trade:||This species was not present in the dried trade from 1998-2001 (Vincent et al. 2011a). It may be used in the aquarium trade as other pipefishes often are Vincent et al. 2011b), but this has not been observed and levels of offtake are unknown.|
|Major Threat(s):||There are no major threats known for this species. However, since it is found in estuaries, coastal development and pollution may be a local threat to this species in some areas of its range.|
|Conservation Actions:||There are no known conservation measures for this species. However, its distribution falls into a number of Marine Protected Areas in the Eastern Tropical Pacific region (WDPA 2006).|
