Methods

Diurnally active non-cryptic species fish above 8cm were surveyed across 21 reef sites across the inner islands of Seychelles, both in no-take and in fished areas. Eight to sixteen replicate 7 m radius point counts were surveyed along the reef slope on each reef site. Fish abundance and individual body length (nearest cm) were estimated in each point count area using underwater visual census (UVC). Fish were counted in order of most mobile to sedentary, to avoid double counting. Biomass was obtained with published lengthweight relationships (Letourneur et al. 1998; FishBase)
