  • IUCN Red List Assessment, Doryrhamphus janssi

    Threats (see Appendix for additional information) Doryrhamphus janssi is threatened by coral reef habitat loss due to coastal development and pollution; destructive fishing practices such as dynamite fishing and trawling; and the effects of climate change including ocean acidification and rising sea surface temperatures (Bruno and Selig 2007; Carpenter et al. 2008; De’Ath et al. 2012; Normile 2016).

    This species would likely benefit from international measures to mitigate anthropogenic climate change.

    One third of reef building corals face elevated extinction risk from climate change and local impacts.
