This study comprehensively documents fish diversity of the family Syngnathidae in Malaysia and its adjacent waters. The results from the present study and records of syngnathids from museum collections and reviewed literature were collated. High species richness with a total of 50 species encompassing all subfamilies of the Syngnathi- dae, the Hippocampinae, Doryrhamphinae, Syngnathinae and Solegnathinae, were recorded from Malaysian waters. Two species Siokunichthys bentuviai Clark 1966 and Syngnathus pelagicus Linnaeus 1758 were previously not known to be distributed within the Malaysian region. Highest species richness was recorded from the Semporna Islands, Sabah. Habitats where syngnathids were recorded include marine macroalgal beds, coral reefs, coastal areas, estuaries, rivers and streams. Syngnathid fishes appear to be cryptic, live in low densities and display patchy distributions. The major threats to syngnathid conservation in Malaysia include overexploitation, by-catch, habitat destruction and degradation, recreational activities and pollution.

This article analyses the pressures on seahorses and explores conservation responses. It focuses on seahorses (Hippocampus spp.) but also considers pipefishes and seadragons, especially where they can fill gaps in seahorse knowledge. The charisma of many syngnathids can make them good flagship species for threats and solutions in marine conservation. The article combines a synthesis of published literature with new data on the trade in seahorses for traditional medicine, aquarium display and cur...

A total of 1951 species of freshwater and marine fishes belonging to 704 genera and 186 families are recorded in Malaysia. Almost half (48%) are currently threatened to some degree, while nearly one third (27%) mostly from the marine and coral habitats require urgent scientific studies to evaluate their status. Freshwater habitats encompass the highest percentage of threatened fish species (87%) followed by estuarine habitats (66%). Of the 32 species of highly threatened (HT) species, 16 are fre...

Seahorses (genus Hippocampus) form a group of over 30 species of enigmatic and charismatic marine fish that are attracting increasing global concern for their threatened status. Particular issues include the overexploitation of seahorses in target and bycatch fisheries and their utilization for traditional Chinese medicines. Seahorses are also thought to be highly vulnerable to habitat loss and deterioration throughout their circumglobal range in temperate and tropical shallow seas. A suite of u...

During the past six years, 15 new seahorse species (Syngnathidae: Hippocampus) have been described on the basis of morphological characters. This approach is known to be problematic, and most species names in Hippocampus are now considered to be synonyms. Genetic methods have great potential to resolve the confused taxonomy of the genus, but none have yet been incorporated into species descriptions. In the present study, mitochondrial control region and cytochrome b DNA sequences, as well as mor...

Seahorses and their syngnathid relatives have provided a focus for efforts to ensure sustainable use of marine resources, with new international trade controls (CITES Appendix II) implemented in May 2004. We demonstrate how a study of international trade can be used to assess relative levels of threat and set domestic research and conservation priorities. Australia has remarkably high syngnathid biodiversity with at least 14 seahorse species, two endemic sea dragon species, and 90 species of pip...

Hippocampus comes is presently exploited at significant rates in the central portion of 鈥 and possibly throughout 鈥 its range. The species is traded in dried form for traditional medicine and alive for the aquarium trade. Here we provide the most current life history, abundance and distribution information available for H. comes. These data should be helpful to researchers, and to management agencies in countries signatory to the Convention on International Trade in Endangered Species of Wild Fa...

Four distinct phylogeographical patterns across Southeast Asia were observed for four species of seahorse (genus Hippocampus ) with differing ecologies. For all species, genetic differentiation (based on cytochrome b sequence comparisons) was significantly associated with sample site (桅 桅 桅 ST = 0.190鈥0.810, P < 0.0001) and with geographical distance (Mantel鈥檚 r = 0.37鈥0.59, P < 0.019). Geographic locations of genetic breaks were inconsistent across species in 7/10 comparisons, although some sim...

Mitochondrial control region (mtDNA CR) diversity within and among 6 seahorse pop- ulations associated with the Indo-Pacific Hippocampus kuda complex (H. kuda from India, Malaysia, Indonesia and the Philippines, H. fuscus from the Red Sea and H. capensis from South Africa) was compared to determine whether there was support for the hypothesis that seahorses are able to colo- nize remote areas by means of rafting. Analyses performed on the data-set included phylogenetic re- constructions, estimat...

The alligator pipefish, Syngnathoides biaculeatus, is a cryptic species commonly found in seagrass meadows. The fish is shy and slow, and it is unknown how the predaceous fish hunts its mobile prey. This study determined its feeding behaviour in an artificial setting of open and vegetated area in an aquarium. Fish behaviour was observed and studied during the early feeding and post-feeding event. The behaviour of 14 pipefish was individually recorded for a duration of 10聽min each for each event,...

Brain size varies greatly at all taxonomic levels. Feeding ecology, life history and sexual selection have been proposed as key components in generating contemporary diversity in brain size across vertebrates. Analyses of brain size evolution have, however, been limited to lineages where males predominantly compete for mating and females choose mates. Here, we present the first original data set of brain sizes in pipefishes and seahorses (Syngnathidae) a group in which intense female mating comp...

Abstract Unsustainable wildlife trade negatively impacts wild populations of traded species. Thus to assess these population impacts and manage trade, we need to find and characterize extant populations. Seahorses are one of the most heavily traded marine animals, with almost 6 million individuals exported worldwide annually. Thailand, the top exporter, is responsible for 88% of global export volumes of dried seahorses. Here, we sought to locate seahorse hotspots in Thailand - places where seaho...

Hippocampus barbouri is one of the seahorse species found in shallow water of Malaysia. It is used as known as a global trade species in ornamental fish industry. To date, there is no documented report on seahorse aquaculture especially for H. barbouri in Malaysia even in Southeast Asia region. Seahorse aquaculture should be considered as an alternative source of seahorses to reduce the pressure on wild population. Therefore, this study was conducted to establish suitable techniques for broodsto...

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 and larval meroplankton as juveniles (for H. trimaculatus only). The similar short relative gut length (锟 0.4) of both species is consistent with a carnivorous diet. Both species are considered specialists in prey selection, focusing on slow-moving ep...
