Abstract: Field survey and stock assessment of shallow-water echinoderms, with emphasis on commercially valuable holothuroids (sea cucumbers), conducted around Yap Island, Federated States of Micronesia, from 27 July to 9 August 2007. The study surveyed 19 reef and lagoon sites using timed swims to estimate catch per unit effort, size distributions, and species composition. A total of 66 echinoderm taxa were identified, including 33 holothuroids, with at least four species likely new to science. Key commercial species documented include Holothuria whitmaei, Holothuria scabra, and Thelenota ananas. The report evaluates population structure, habitat distribution, and harvesting pressures associated with the beche-de-mer trade, and provides initial fisheries management recommendations including moratoria, size limits, and marine protected areas. It serves as both a biodiversity baseline and an applied fisheries management reference for Yap State.
