“…Therefore this list can be seen as near complete, though future surveys may reveal new additions. The diversity of these reefs is similar to others in the Western Indian Ocean (WIO) that have used visual censuses as their primary data collection method (Maggs et al, 2010;Chabanet & Durville, 2005;Gillibrand, Harries & Mara, 2007;Durville, Chabanet & Quod, 2003). When authors have chosen to comprehensively include species present in historical records (e.g.…”

“…If this still wasn't possible, they were labelled 'unknown'. Eight trophic categories were used, as in Gillibrand, Harries & Mara (2007); Chabanet & Durville (2005); and Durville, Chabanet & Quod, (2003). These were: herbivore; omnivore; browser of sessile invertebrates; diurnal carnivore; nocturnal carnivore; piscivore; diurnal planktivore; and nocturnal planktivore.…”

The coral reefs around Praia do Tofo, southern Mozambique, are known for their aggregations of marine megafauna but as yet few studies have comprehensively examined their broader biodiversity. This study is the first to assess the ichthyofaunal diversity of this economically important area. Methodology involved SCUBA and snorkel underwater visual censuses conducted between February and May, 2016, and the use of photographic records from 2015 to capture rare species. A total of 324 species, representing 79 families, were recorded from 16 reefs in the region. The area shows comparable species diversity and notably high family diversity in relation to other areas of the Western Indian Ocean. The trophic structure of the reefs, similar to that recorded in the wider region, suggests the reefs are in good health and fairly resilient to disturbance. This study highlights the area’s high biological value beyond its megafauna and lends support to greater management of these ecosystems for the benefit of the associated human population.

“…These authors examined a smaller area than the current study and recorded 334 species by conducting visual observations across a twelve month period. In contrast, Chabanet and Durville (2005) recorded more than 50 fewer species around Juan de Nova island through 30 hours of visual surveying. This highlights that sampling effort does not solely account for the high fish diversity recorded in the PTPB area.…”

“…These results provide a higher estimation of fish species richness than is predicted by the Coral Fish Diversity Index. The diversity of the PTPB area is similar to that recorded in other areas of the southwestern Indian Ocean where visual observations have been the primary data collection method (Table 3) (Maggs et al ., 2010; Chabanet & Durville, 2005; Gillibrand, Harries & Mara, 2007; Durville, Chabanet & Quod, 2003). In particular, SR theor shows high similarity to areas in southern Mozambique and South Africa that are fully or partially protected (e.g.…”

Reef fishes of praia do Tofo and praia da Barra, Inhambane, Mozambique

The coral reefs around Praia do Tofo and Praia da Barra, southern Mozambique, are known for their aggregations of marine megafauna but few studies have examined their reef fish biodiversity. This study assesses for the first time the ichthyofaunal diversity of the seas around Praia do Tofo and Praia da Barra. Methods involved underwater observations during recreational dives between February and September 2016, and the use of photographic records from 2015. A total of 353 species, representing 79 families, were recorded from 16 patch reefs in the region. The area shows comparable species diversity to others in the southwestern Indian Ocean, suggesting these reefs are in good condition. But high primary productivity driven by coastal upwelling may make fish diversity and trophic structure unreliable measures of the health of these reefs. Future studies investigating the sustainability of this ecosystem would benefit from utilising a wide range of reef health measures.

“…In spite of their reduced terrestrial area (from 30 km 2 for Europa to 1 km 2 for Tromelin; absence of terrestrial area for Bassas da India), these islands share an exceptional natural heritage including many marine and terrestrial endemic species. At a regional scale the Iles Eparses are some of the most pristine ecosystems, largely preserved from anthropogenic impacts due to their geographical isolation and a historically very limited human occupation (Le Gall et al, 1985;Barré and Servan, 1988;Le Corre and Jouventin, 1997;Le Corre and Probst, 1997;Probst et al, 2000;Le Corre and Safford, 2001;Probst et al, 2001;Durville et al, 2003;Boullet, 2005;Chabanet and Durville, 2005;Boullet, 2006;Gravier-Bonnet and Bourmaud, 2006a;Gravier-Bonnet and Bourmaud, 2006b;Quod et al, 2007;Boullet, 2008a;Boullet, 2008b;Bourjea et al, 2011;Poupin et al, 2013a;Poupin et al, 2013b;Boullet, 2014;Dumeau et al 2014;Chabanet et al, 2016;Conand et al, 2016;Poupin, 2016;Quétel et al, 2016). The Iles Eparses are among the last sanctuaries of marine and terrestrial tropical biodiversity in the southwest Indian Ocean (Quétel et al, 2016).…”
