| Coastal populations of maritime countries in eastern Africa rely on fish as a primary source of protein, but baseline information on the abundance of fish communities on these coastlines is often lacking. We used baited remote underwater video stations to compare the abundance and diversity of reef fishes targeted by fishing at two sites in southern Mozambique, one at Lighthouse Reef within the Bazaruto Archipelago National Park and the other to the south at San Sebastian Reef on the San Sebastian Peninsula. Fish that are known targets of fisheries (mostly small-scale and artisanal) had an abundance that was almost three-times greater at San Sebastian Reef (80.22 ind. h–1 [SE 18.00]) than at Lighthouse Reef (29.70 ind. h–1 [SE 8.91]). Similarly, there was... |

| The ichtyofauna of Geyser and Zelee coral banks (north of Mozambique canal) was investigated in 1996, this work being the first quantitative study on this area. Quantitative data were collected on 11 stations (mean depth 18 m) by visual observations along 50 m transect, widened to 2 m for small sedentary species, and to 5 m for commercial species with a large action range. The main descriptors of the fish communities (species richness, abundance per species) and the trophic structure (omnivorous, herbivorous, carnivorous, browsers of sessile invertebrates) were described and analysed.A total of 294 fish species, belonging to 43 families were recorded. The species richness varied from 45 to 83 species / station, and the abundance, from 292 to 1322... |

| • In order to assess the sustainability of fish resources in the Natural Marine Park of Mayotte (Western Indian Ocean), indicators and monitoring protocols must be determined. • This study relied on the underwater video technique STAVIRO for assessing fish communities and resources. A pilot survey was conducted in Nov. 2014 in the south-east quarter of the Mayotte lagoon, an area encompassing the marine reserves of Longogori, M’Bouzi and the Saziley Marine Park. Out of 115 stations collected, 104 were analysed for habitat and fish, based on a list of 527 species with fishing, ecological, or emblematic interest (cf. AMBIO/A/1). • 43 indicators were computed, analysed, and for some mapped. The PAMPA computing tool was used in this purpose. • 130 fish species... |
