The live seahorse trade in Los Angeles

Global seahorse populations (Hippocampus spp.) are under pressure from habitat degradation, accidental capture (bycatch), and direct exploitation. Seahorses are primarily traded for use in traditional Chinese medicine and its derivatives, but they are also sold as dried curiosities and live for ornamental display in aquariums. In 2002, all seahorse species were included on Appendix II … Read more The live seahorse trade in Los Angeles

Potential techniques for marking and tagging seahorses

Marking seahorses for research and husbandry was first undertaken in the early 1990’s. In the last fifteen years there has been notable progress adapting marking and tagging methods for perciform fish to the dissimilar morphology of seahorses, but published data remain scarce.

Home range behaviour of the monogamous Australian seahorse, Hippocampus whitei

We provide a quantitative account of local movements in the monogamous Australian species Hippocampus whitei, as a rare report of home range size in fishes living in seagrass habitats. Our study took place in shallow Posidonia seagrass beds in Port Jackson (Sydney Harbour), principally during January to March. Daily monitoring of individual seahorses during underwater … Read more Home range behaviour of the monogamous Australian seahorse, Hippocampus whitei

Life history, ecology and conservation of European seahorses

My thesis examined the implications of life history and ecology for population-level responses of the European long-snouted seahorse (Hippocampus guttulatus Cuvier 1829) to habitat alteration, exploitation and a recommended minimum size limit for seahorse management. The research employed a mark-recapture study, underwater visual censuses (UVCs) and catch data from an unrelated experimental sampling program in … Read more Life history, ecology and conservation of European seahorses

Phylogeography of Southeast Asian seahorses in a conservation context

This thesis investigates the potential role of historical isolation of ocean basins in promoting diversification among marine organisms in Southeast Asia. It also questions the possible effects of Pleistocene exposure of the Sunda Shelf on present day marine distributions and genetic diversity. Four species of exploited seahorses (genus Hippocampus), with differing ecological parameters, are used … Read more Phylogeography of Southeast Asian seahorses in a conservation context

Life history and ecology of seahorses: implications for conservation and management

We present the first synthesis of the life history and ecology of seahorses, compare relationships for seahorses with other marine teleosts and identify research needs. Seahorses occurred primarily amidst temperate seagrasses and tropical coral reefs. Population densities were generally low, ranging from 0 to 0·51 individuals m−2, but reached 10 m−2 in some patches. Inferred life spans … Read more Life history and ecology of seahorses: implications for conservation and management

A Guide to the Identification of Seahorses

Developed in collaboration with TRAFFIC North America, the Guide to the Identification of Seahorses includes detailed descriptions and images all species currently recognized by Project Seahorse, the leading authority on seahorses and their relatives. It provides a straightforward methodology for identifying seahorses. Download Identification Guide (pdf) Lourie, S.A., S.J. Foster, E.W. T. Cooper, and A. … Read more A Guide to the Identification of Seahorses

Bycatch of lined seahorses (Hippocampus erectus) in a Gulf of Mexico shrimp trawl fishery

Bycatch studies have largely ignored population level effects on fish species of little commercial interest. Here we analyze bycatch of the lined seahorse (Hippocampus erectus) in the bait-shrimp trawl fishery in Hernando Beach, Florida, providing the first fisheries data for this species. Based on catch per unit of effort (CPUE), size, sex, and reproductive status … Read more Bycatch of lined seahorses (Hippocampus erectus) in a Gulf of Mexico shrimp trawl fishery
