Threats [top]

Major Threat(s): The are no known major threats to Hippocampus sindonis.

Seahorses are vulnerable to a number of threats. This species is not known for any commercial trade, however it maybe taken as by-catch, susceptible to coastal habitat degradation, or exploited for the Chinese medicine trade or ornamental trade.

This species may be particularly susceptible to decline. All seahorse species have vital parental care, and many species studied to date have high site fidelity (Perante et al. 2002, Vincent et al. in review), highly structured social behaviour (Vincent and Sadler 1995), and relatively sparse distributions (Lourie et al. 1999). The importance of life history parameters in determining response to exploitation has been demonstrated for a number of species (Jennings et al. 1998).

Conservation Actions [top]

Conservation Actions: Hippocampus sidonis has been listed under CITES appendix II ensuring that international trade of this species is monitored. This species may be found to occur in a number of marine protected areas within its range.

Further research is needed on the biology, ecology, threats and population trends of this species.

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
