NIMR.<br />
d) Commercial Fish Abundance<br />
Observations made whilst exploring the reefs have shown the existence <strong>of</strong> a<br />
number <strong>of</strong> commercial fish species <strong>of</strong> relatively high abundance, namely blackspotted<br />
sweetlips (Plectorhinchus gaterinus), goldspotted sweetlips (Plectrohinchus<br />
flavomaculatus) and several species <strong>of</strong> snapper (Lutjanidae spp). In particular, site 2 had<br />
high numbers <strong>of</strong> black spotted and gold spotted sweetlips present. All <strong>of</strong> the surveyed<br />
sites had abundant populations <strong>of</strong> surgeonfish and parrotfish. Low numbers <strong>of</strong> groupers<br />
were observed during commercial fish swims.<br />
A small number <strong>of</strong> the commercial fish species looked for were present at site 1 at<br />
NIMR. Highest abundances were recorded for surgeonfish (Acanthuridae spp.),<br />
parrotfish, and black spot snappers and emperors (Figure 12). Other recorded families<br />
include snappers, sweetlips, goatfish, triggerfish, and fusiliers.
