In this paper we compare changes in populations of sea cucumbers that were surveyed on reef flats around Buka Island, in the Autonomous Region of Bougainville (ARB) in 1992 and 2008. Over this 16-year period, the abundances of eight species of sea cucumber declined dramatically. By 2008, six of the eight species sighted in 1992 and 2008 — Actinopyga echinites, A. miliaris, Bohadschia similis, Holothuria atra, H. coluber and H. scabra — had declined to between 1% and 5% of their 1992 abundances, providing quantitative evidence that the sea cucumber fishery in the ARB is severely overfished. In 1992, H. scabra, H. atra and B. similis constituted 92% of the sea cucumbers sighted on reef flats. These species were also the three most abundant sea cucumbers in the 2008 survey, comprising 62% of all sea cucumbers seen. Relatively high abundances of Actinopyga mauritiana and Bohadschia vitiensis were also sighted in 2008, species that were not encountered in the 1992 survey.
