| Fishing performances of four different types of boats (pirogues, outboard, whalers, schooners) are studied through the analysis of the temporal evolution, between July 1985 and June 1988, for four parameters: numbers of active fishing boats,- total number of fishing trips, - average number of trips/boat, - average trip duration. The trends from these analysis reveals that the boats involved in the handline fishery in seychelles have evolved considerably. These changes must be taken into consideration in the case of an eventual reorganisation of the fleet. |

| 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... |

| 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. |

| 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... |

| Shark species, both oceanic and coastal, are very common to Seychelle waters. In the past, however, the demand for shark and shark products has always been very erratic. The ever-increasing international concern for the species and potential conflicts between fishermen and conservation groups has highlighted the issue. In the Seychelles, the shark are caught by gillnets in inshore waters and by hook-and-line and purse seine offshore. Until very recently there were no regulations controlling the shark fishery, but, partly in response to initiatives by a local conservation group, fishing for sharks with nets has been banned since 1 August 1998. A review is provided of the present situation of the fishery whilst underscoring the difficulties of formulating a... |

| Net fishing is an important component of the artisanal fishery of the Seychelles. It is composed of beach seine, encircling and set gillnets. This report reviews net fishery and its impact on the environment and fish stocks and provides a framework for its management. There are no current management measures for the traditional net fisheries except that all nets above 50 metres requires a license with a lead seal bearing the licence number. Certain irresponsible uses of these nets have ben acknowledged, principally the 'Met outaz' fishing strategy, incidental catch of marine mammals and the presence of commercially important juvenile fish in the beach seine fishery. SFA has addresses these issues rationally and management options are explored followed by... |

| 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... |

| This report reviews the lobster catch during the months of November and December 1992. In total, 38 fishing units were licenced: 26 on Mahe, 7 on La Digue and 5 on Praslin. 8 licence holders provided no information and claimed that they undertook no fishing trips at all. Of the remainder, each fishing unit comprised an average of 3 men. 2 fishing units used traps as the only catching method, 27 used snorkelling and 1 a combination of traps and snorkelling. For the two month period, an estimated catch of 4.9 tonnes of Spiny Lobster for all sites were landed; of which Mahe contributed an estimated 2.8 tonnes. For the month of November only, a total catch of 2.7 tonnes of lobsters were estimated and for the month of December a total of 2.2 tonnes were... |
