We adapted a visual census method, mainly used in demersal and reef fish studies, to characterize fish communities associated to drifting fish aggregating devices (FADs) in the Western Indian Ocean. Drifting FAD associated fishes from both equatorial (Seychelles) and tropical waters (Reunion Island) were examined by divers. A total of 32 species (belonging to 16 families) were observed associated with drifting FADs in equatorial waters, and 24 species (14 families) were found around FADs in tropical waters. Twenty species were found in both regions. The highest number of species observed at a single FAD was 18 (12 +/- 2, mean +/- SD) in equatorial and 13 (10 +/- 3) in tropical waters, not counting circumnatant species loosely associated with the FAD. Some... |

Climate change is one of the greatest threats to the long-term maintenance of coral-dominated tropical ecosystems, and has received considerable attention over the past two decades. Coral bleaching and associated mortality events, which are predicted to become more frequent and intense, can alter the balance of different elements that are responsible for coral reef growth and maintenance. The geomorphic impacts of coral mass mortality have received relatively little attention, particularly questions concerning temporal recovery of reef carbonate production and the factors that promote resilience of reef growth potential. Here, we track the biological carbonate budgets of inner Seychelles reefs from 1994 to 2014, spanning the 1998 global bleaching event... |

The genus Amphiprion Bloch & Schneider, 1801, is represented in the Seychelles by two species, A. akallopisos Bleeker, 1853, and the endemic A. fuscocaudatus Allen, 1972. Throughout its distributional range Amphiprion akallopisos has exclusively been recorded to associate with the clownfish anemones Heteractis magnifica (Quoy & Gaimard, 1833) and Stichodactyla mertensii Brandt, 1835. During the Netherlands Indian Ocean Programme (NIOP) Seychelles Expedition 19921993 this was confirmed for the Seychelles, although the species was predominantly found with H. magnifica, the most common host anemone in the islands. So far, Amphiprion fuscocaudatus had exclusively been reported as a symbiont of Stichodactyla mertensii. During the NIOP Seychelles... |

The evolutionary relationships between island and mainland faunas of the 24 species of insular freshwater crabs in the Afrotropical region are reviewed in the light of phylogenetic studies. Twenty insular species of freshwater crabs are endemic, and four are also found on the neighboring mainland of Africa. The Atlantic Ocean islands of Sherbro, Bioko, Príncipe, and São Tomé support five species of Potamonautidae, while the Western Indian Ocean islands of the Seychelles, Zanzibar, Pemba, Mafia, and Madagascar together have 16 species of Potamonautidae, and Socotra has three species of Potamidae. Disjunct distributions of non-endemic insular species of Afrotropical freshwater crabs with conspecifics on the mainland are the result of past lower sea levels... |

A new genus of parthenopid crab, Garthambrus gen. nov., characterised by a broad carapace with strongly raised branchial and gastric regions, distinctive rostrum, sub-cylindrical ambulatory meri and a long distal segment of the second male pleopod, is established for six deep water species from various parts of the Pacific. A new species, Garthambrus posidon spec, nov., is also described from depths of between 480 to 600 m off the Seychelles in the Indian Ocean. It differs from its closest congener, G. poupini (Garth, 1993), in having a proportionately broader carapace, less granulated carapace and chelipedal surfaces, and in the form of the carapace regions. |

Distant water fishing nations (DWFN) began longlining for tuna in the Western Indian Ocean (WIO) in the early 1950s, initiated by the Japanese soon followed by the Taiwanese (1954) and Koreans (1960). Large scale industrial purse seining began in 1983 when the French and Spanish fleets moved into the Western Indian Ocean from the tropical Atlantic. By 1986 some 6 % of the world tuna catch (143,099t out of 2,400,000t) was coming from the WIO purse seiners; by 1997 this had risen to 14 %. Virtually all the purse seiners active in the WIO are licensed to fish in the Seychelles EEZ; SFA's data therefore reflect the entire WIO purse seine catch (based upon daily catch and effort reports or logbooks which must be provided to SFA by all licensed vessels).
