Journal Article
2015
Life-history variables for three incidentally captured species of seahorse (Kellogg's seahorse Hippocampus kelloggi, the hedgehog seahorse Hippocampus spinosissimus and the three-spot seahorse Hippocampus trimaculatus) were established using...
Journal Article
2015
The effective design of species conservation programs is reliant on information such as extant geographic distribution, taxon-specific life-history characteristics, and the relative influence of historic processes and contemporary environmental...
Journal Article
2015
A significant decline in the seahorse populations in the Ria Formosa has been recently reported and holdfast availability suggested as a particularly important variable that influences the abundance of the long-snouted seahorse (Hippocampus...
Journal Article
2015
Comparisons of three sets of surveys in the Ria Formosa Lagoon, Portugal, over a 13 year period (2001–2002, 2008–2009 and 2010–2013) revealed significant population fluctuations in at least one of the two seahorse (Hippocampinae) species living...
Journal Article
2015
For many small-scale, tropical reef fisheries, landed catch may be the only data that can be monitored to assess the impacts of management. This is true for seahorses Hippocampus comes that are obtained as part of a multi-species fishery in the...
Journal Article
2014
In this study, the spot pattern in Hippocampus guttulatus was analysed using a computer programme algorithm that allowed individual comparison. This methodology was first tested in a controlled environment using 51 adult and 55 juvenile H....
Journal Article
2014
Ecologically sound fisheries management and improving future food security require that small fish by-catch in tropical shrimp trawl fisheries is maintained at, or reduced to, sustainable levels; restricting trawling in particular places, or at...
Journal Article
2014
1. In principle, the database generated by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) offers an unparalleled opportunity to analyse trade in species of conservation concern. 2. The value of the...
Journal Article
2014
Two seahorse species, Hippocampus spinosissimus and Hippocampus trimaculatus, sampled in east and west coastal waters of Peninsular Malaysia, fed mostly on crustacean prey; small caridean shrimps and amphipods as adults (both species), and copepods...
Journal Article
2014
Concerns regarding the sustainability of the seahorse Hippocampus spp. trade led to their listing on CITES Appendix II in 2002, with implementation in 2004. In 2007 we interviewed wholesale traders of seahorses in Hong Kong, China, seeking...
Journal Article
2014
All possible tools need to be marshalled for marine fish conservation. Yet controversy has swirled around what role, if any, the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) should play for marine fishes....
Journal Article
2014
Small-scale fisheries catch and effort estimates are often built on incomplete data because they overlook women’s fishing. Women do participate in small-scale fisheries, and often in ways distinct from men’s fishing. Hence, the inclusion of women’s...
Journal Article
2014
Marine ecosystem–scale fisheries research and management must include the fishing effort of women and men. Even with growing recognition that women do fish, there remains an imperative to engage in more meaningful and relevant gender analysis to...

Ending illegal, unregulated, and unreported fishing would bring hope for ocean wildlife.
Journal Article
2014
Marine debris, mostly consisting of plastic, is a global problem, negatively impacting wildlife, tourism and shipping. However, despite the durability of plastic, and the exponential increase in its production, monitoring data show limited evidence...
Journal Article
2013
Assessing connectivity of the marine environment is a fundamental challenge for marine conservation and planning, yet conceptual development in habitat connectivity has been based on terrestrial examples rather than marine ecosystems. Here, we...
Journal Article
2013
1. Coral-reef managers must detect and reverse collapses in habitat and evaluate the success of such interventions. Since these responsibilities must be met with limited time and resources,methods used should balance statistical power with practical...
Journal Article
2013
The recent decline of the seahorse populations in the Ria Formosa lagoon could indicate the presence of a stressful factor due to habitat loss. Artificial structures have been successfully used as a recovery tool to cope with habitat degradation...
Journal Article
2013
To understand how a sedentary fish responds to displacement and identify key habitat characteristics for that fish, we translocated long-snouted seahorses (Hippocampus guttulatus) within their natural habitat but far beyond their home range. After...
Journal Article
2013
The present research provides the first demographic reference points for tropical seahorses, relevant to conservation of this largely tropical genus Hippocampus, which is listed on the Convention on International Trade in Endangered Species of Wild...

Position Statement
April 18, 2009
Project Seahorse recognizes that a sustainable trade in syngnathids for the public aquarium market has a role to play in the conservation of seahorses and pipefishes (syngnathids). All consumers of...
Position Statement

Project Seahorse supports environmentally and socially responsible syngnathid aquaculture. Syngnathid aquaculture has received much attention recently both as a potentially lucrative commercial...
Position Statement
April 18, 2009
Project Seahorse encourages the careful management of captive syngnathids so as to ensure that casual releases into natural habitats do not occur. Syngnathid populations are threatened in some parts...
Position Statement
April 18, 2009
Project Seahorse cautions against mating across different species (hybridization) of seahorses and pipefishes (syngnathids). Trade in hybrid offspring of such matings may compromise captive breeding...

As with many fish species, seahorses (genus Hippocampus) attain their highest species richness in Southeast Asia/Australasia. It is likely that the complex geological history of the region and the effects of Pleistocene sea-level changes have...
