Implementation of CITES Appendix II listings for marine fishes

This Information Document makes recommendations to enhance implementation of the Convention for marine fishes included in CITES Appendix II. It is a contribution from a workshop attended by experts in marine fisheries and CITES implementation, participating in their individual capacities. A report of this workshop1 and list of participants can be found at www.iucn-seahorse.org/citesmarine. This … Read more Implementation of CITES Appendix II listings for marine fishes

Simple is good: moving toward pragmatic and effective monitoring to support CITES implementation for marine fishes and invertebrates on Appendix II

This document explores the challenges and opportunities of monitoring populations, fisheries and trade of marine fishes and invertebrates listed on CITES Appendix II, in support of ensuring sustainable trade through adaptive management. It addresses listings for a wide variety of species, including European eel, giant clams, humphead wrasse, queen conch, rays, seahorses, sharks and sturgeons. … Read more Simple is good: moving toward pragmatic and effective monitoring to support CITES implementation for marine fishes and invertebrates on Appendix II

Implementing Appendix II listings for marine fishes: important considerations when making non-detriment findings

This document summarizes key advice for making non-detriment findings (NDFs) for marine fishes1 listed on CITES Appendix II2 . It highlights the importance of, where possible: (i) making NDFs before removing specimens from the wild; (ii) making NDFs at an appropriate geographic scale; (iii) considering all types of wild extraction, and all sources of mortality, … Read more Implementing Appendix II listings for marine fishes: important considerations when making non-detriment findings

iSeahorse: seahorse conservation through citizen science.

Context Urgent action is needed to track and protect seahorse populations around the world — and the few researchers focused on these important animals worldwide are not going be able to do it alone. Seahorses are threatened by overfishing, harmful fishing practices, and habitat degradation and loss — including the destruction of coral reefs. Every … Read more iSeahorse: seahorse conservation through citizen science.

Trends in seahorse abundance in the Ria Formosa, South Portugal: recent scenario and future prospects

In the last decade, seahorse population census in the Ria Formosa identified stable populations of Hippocampus guttulatus and H. hippocampus at the highest densities described for these species worldwide. However, recent studies in the Ria reported a significant decrease in seahorse numbers of 94% for H. guttulatus and 73% for H. hippocampus. Therefore, this study … Read more Trends in seahorse abundance in the Ria Formosa, South Portugal: recent scenario and future prospects

Habitat use, movement, and vulnerability of sedentary fishes in a dynamic world

In this thesis I quantify habitat use, movement, and vulnerability for seahorses and other sedentary fishes to understand how they may respond to habitat related threats. Surviving habitat change depends on either acclimatizing or escaping. Sedentary animals could be especially vulnerable if they require specific habitats or their ability to escape is reduced. However, dynamic … Read more Habitat use, movement, and vulnerability of sedentary fishes in a dynamic world

Saving seahorses means saving our seas

With their horse-like heads, monkey-like tails, kangaroo-like pouches, and chameleon-like eyes, seahorses are among the strangest and most iconic fish species in our oceans. Adult seahorses have few predators, thanks to their ability to change colour and grow skin filaments to blend in with their surroundings. Their bony plates and spines make them unappealing to … Read more Saving seahorses means saving our seas

Seahorses, from community support to global policy change

MY Darwin Initiative grant, for Conservation biology of seahorses and pipefishes (1994-1996), has made a global conservation impact. Darwin funding allowed me to launch conservation field-work with colleagues in Vietnam and the Philippines. In collaboration with communities, we looked at the biology of seahorses and pipefishes, the ecological and socioeconomic importance of their exploitation, and … Read more Seahorses, from community support to global policy change

Biology, fishery and trade of sea moths (Pisces: Pegasidae) in the central Philippines

Sea moths (family Pegasidae) are little-studied benthic fish, found throughout the Indo-Pacific. Two species of sea moths, Pegasus volitans and Eurypegasus draconis, are caught incidentally in illegal trawl gear in the Philippines and sold into the dried fish trade. Approximately 130,000–620,000 P. volitans and 130,000 E. draconis were landed off north-western Bohol alone in 1996. An additional 43,000–62,000 sea moths (predominantly P. volitans) … Read more Biology, fishery and trade of sea moths (Pisces: Pegasidae) in the central Philippines
