Abstract—The fish diversity of intertidal rock pools in the Glorieuses Islands was investigated using clove-oil anaesthetic. That method, is easy to use and safety is well adapted for this type of census. A total of thirty two species belonging to 14 families were sampled. Of these, 19 were observed as adults in most stations and represented the ty...

Inland eruptions of the Piton de la Fournaise located in the south east part of Réunion are often and may reach sometimes the ocean.Categories of lava are mostly Aa types but in 2004, a pillow lava (pahoehoe) flow was observed underwater by our team. Types of lava depend on their silica contains which affect its viscosity. In april 2007, classic Aa...

An important eruption of Piton de La Fournaise on the Reunion Island started at April 2007. A large number of killed fishes were found floating on the sea infront of lava flows. More than 400 specimens were caught: 81 species for 42 families were identified. In the majority, these were deep species living between -100m and -1000m depth. 47 species...

Une exploration sous-marine à l'aide d'un engin de type R.O.V a été menée pour la première fois entre 100 et 400 m de profondeur sur les reliefs volcaniques de l'île de la Réunion. 20 plongées ont été effectuées dans le sud-est de l'île sur les coulées récentes et 13 dans l'ouest sur un substrat plus ancien. Des pillow-lavas ont ainsi été observées...

A field survey conducted with a R.O.V. submarine system has been carried out for the first time between 100 and 400 m deep on the volcanic slopes of Reunion Island. 20 dives were conducted in the south-east of the island on the recent volcanic lava flows, and 13 dives were conducted in the west coast, associated with older geological substrates. Pi...

This paper constitutes the first study on reef fish communities at Juan de Nova, one of the Eparses Islands in the Mozambique Channel. These remote islands, with no permanent habitation, except a small military base, represent sites which experience minimal direct human influence. Sampling was firstly done by underwater visual observations, using S...

The ichthyofauna of Reunion Island, Southwestern Indian Ocean, was sampled during several ecological and artisanal fisheries studies. Information from these investigations and from other sources were included to compile the present checklist of the marine fishes of the island. A total of 885 species belonging to 150 families was recorded. Nine spec...

In order to measure the effects of clove oil on coral colonies, we used a clove oil-ethanol solution, a chemical used in particuler to anaesthetise and collect fishes in situ, and studied its effects on the hermatypic Scleractinaire, Pocillopora verrucosa. Loss of colouration and bleaching of coral colonies followed single or repeated exposures to...

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 w...

The colonization of a fringing reef of Reunion Island by fish larvae takes place essentially from August to February with two peaks, in August-September, when the water temperatures are coldest, and in February when they are at a maximum. The number of fishes, as well as the number of sampled species, present similar values over two consecutive yea...

Three small species of Lutjanidae from Reunion Island, Lutjanus notatus, L. kasmira et L bengalensis, have been reared from juveniles captured in the sea. The initial average weight varied from 5 to 7 g depending on the species. After a growth period of 196 days, it was 34 to 37 g. The results show a higher growth rate for L kasmira and a better su...

Le programme SIREME a pour objectifs de : 1) poursuivre les inventaires d’espèces sous-marines et faire un point d'étape sur l'état de santé des récifs coralliens à travers le suivi des stations GCRMN existantes, et en rajoutant certaines composantes non prises en compte jusqu'à présent, à savoir l’étude du compartiment micro-planctonique et les maladies coralliennes ; 2) continuer la cartographie des habitats des îles Eparses (Glorieuses) et initier celle de Mayotte avec une typologie exhaustive des habitats ; 3) évaluer le degré de connectivité entre les différents sites d’étude ; 4) définir des indicateurs de suivi permettant d'évaluer l'efficacité des mesures de gestion mises en place par les gestionnaires.
