  1. Type: brief

    Surveys of 21 reef sites around the inner granitic islands of the Seychelles. Benthic cover of corals and other organisms were quantified along with the abundance diversity and size of reef associated fishes.

  2. Type: full

    These surveys were first conducted in 1994 by Simon Jennings, now at the Centre for Environment, Fisheries and Aquaculture Science in the UK, and have been subsequently repeated in 2005, 2008 and 2011 by Nick Graham of James Cook University and Shaun Wilson, now at the Western Australian Department for Environment and Conservation. In each year 7 sites on granitic reefs, 7 sites on continuous carbonate reefs, and 7 sites on patch reefs were surveyed. 16 replicate surveys were conducted at each reef site. 9 of the 21 sites are within no-take marine protected areas, while the remaining 12 sites are open to fishing. The data have been used to assess the effectiveness of fisheries management in Seychelles, and more recently to evaluate the impact of the 1998 climate change driven coral mortality event which killed up to 90% of the corals on these reefs.
