A study of recruitment of marine invertebrates around Masig Island and Marsden Island, in central Torres Strait commenced in November 2006 and ended in November 2008.Terracotta settlement plates (11 cm x 11 cm) with well pitted surfaces were deployed at three locations on the northern side of each island, with locations two hundred metres apart. Each location was further divided into three sites, each twenty metres apart. At each site, five plates were deployed, roughly one metre apart, at both six metres and twelve metres depth. The settlement plates were attached to a stainless steel base plate anchored to the reef and rested approximately one centimetre above the reef allowing for settlement and recruitment of organisms on both sides of each plate.The plates were deployed in November, at the start of summer, and in May, at the start of winter. At the end of each season, the top and underside of each plate, which was identified using a small numbered-tag on both sides on one corner, was photographed in situ, removed and a new plate deployed. During the first year plates were also photographed in situ after four months in each season to provide information about the recruitment of benthic organisms within a season.Abundance and percent cover of organisms was assessed from images of tiles displayed by Microsoft Windows XP Picture and Fax ViewerTM on a PC screen. This research was undertaken to assess the recruitment of sessile marine invertebrates in central Torres Strait across seasons and years. Recruitment of the wild commercial bath sponge species, Coscinoderma matthewsi, was of specific interest.
