Résumé : International audience
We explore the relationships within Serraniformes (Li et al., 2009) using a dense taxon sampling and seven nuclear markers. Six had already used been for teleost phylogeny (IRBP, MC1R, MLL4, Pkd1, Rhodopsin, and RNF213) at other scales, and one (MLL2) is new. The results corroborate the composition of Serraniformes described in previous publications (some Gasterosteiformes, Perciformes and Scorpaeniformes). Within the clade, Notothenioidei and Zoarcoidei are each monophyletic. Cottoidei was not monophyletic due to placement of the genus Ebinania (Psychrolutidae). Our independent data confirm the sister-group relationship of Percophidae and Notothenioidei as well as the division of Platycephaloidei in four different groups (Bembridae, Platycephalidae, Hoplichthyidae and Peristediidae with Triglidae). Within Cottoidei, Liparidae and Cyclopteridae formed a clade associated with Cottidae, the genus Cottunculus (Psychrolutidae), and Agonidae. Serranidae and Scorpaenidae are not monophyletic, with the Serranidae divided in two clades (Serraninae and Epinephelinae/Anthiinae) and Scorpaenidae including Caracanthidae and the genus Ebinania (Psychrolutidae). We discuss some morphological characters supporting clades within the Scorpaenidae.

Résumé : International audience
This study determined the movements of a Giant Grouper, Epinephelus lanceolatus, in which an acoustictag was surgically implanted and monitored by an array of six VR2W acoustic receiver units from August 2010 toJanuary 2013 in the remote, uninhabited Chesterfield Islands, Coral Sea (800 km West of New Caledonia). Our datarevealed a home reef area (residency rate of 44.9%) with an increased activity revealed by movements at dawn anddusk toward and between two adjacent reef passages, probably for foraging. The fish was absent from its residentreef between October and December 2010 and 2012, corresponding to the time known for spawning aggregationsof this species in New Caledonia. A skipped spawning seems to have occurred in 2011. We hope these data will becomplemented in the future by locating the spawning site or sites and thus provide adequate conservation measures.The Coral Sea links two World Heritage Sites, the Australian Great Barrier Reefs and the New Caledonian coral reefs.It would be fitting to create a Marine Protected Area for the Chesterfield Islands between these two major conservationareas of the sea.

Résumé : Species with a very high potential for aquaculture, allowing development projects on a short terms basis: the seabass originating from S.E. Asia. Species, potentially interesting but presenting some drawbacks, as difficulties to perform larval rearing or presenting pathological problem. Species considered as difficult to rear and not retained like Siganus argenteus , Siganidae or Caranx ignobilis , Carangidae. The future development of finfish in Polynesia is emphasized and a project of sea bass netcage culture in Polynesian lagoon is presented.

Résumé : In the Caribbean, snappers (Lutjanidae) and groupers (Serranidae) are often heavily exploited by artisanal or industrial fisheries. This paper analyzes the catches of an artisanal fishery selectively targeting these species with a moderate fishing pressure in the Bay Islands (Honduras), and discusses the implications on the understanding of the early stages of development of reef fisheries. Although snappers and groupers are targeted with handlines and spearguns in the whole archipelago, the differences in species diversity and size structure of the catch reveals various exploitation patterns. In most areas, a depletion is observed for the most vulnerable snapper and grouper species, and most other species are mainly exploited in their juvenile phase; clear signs of an intensification process are apparent in one of the areas. The comparison of the relative production in the Bay Islands with other reef fisheries in the Caribbean suggests that higher values may be related to moderate fishing pressure and appropriate combinations of fishing effort and selectivity. This example shows how fisheries strictly targeting a high quality resource with selective fishing techniques can be quite productive even at high levels of effort, but also that they are progressively lead to broaden their species range (sooner or later at the expense of the most vulnerable, often large-sized, species) while increasingly using less selective gears.

Résumé : Centropomidae and Serranidae, sometimes collectively misnamed "sea basses", are suitable for aquaculture in pens, ponds, and raceways around the tropical and subtropical latitudes of the world. Western Atlantic Ocean species were recently considered for farming. South Florida, Mexico, Central and South America and the Antilles areas of the Caribbean Basin have extensive areas suitable for farming groupers and snook. Principal species of interest are the common snook (Centropomus undecimalis ), the fat snook (C. parallelus ), the Nassau grouper (Epinephelus striatus ), Black seabass (Centropristis striatus ), Gag (Mycteroperca microlepis ), and jewfish (E. itajara ).

Résumé : 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 species are known only from Reunion, indicating endemism of about 1.0%. The most speciose families (Labridae, Gobiidae, Serranidae, and Pomacentridae) were also among the most speciose at the neighbouring Mauritius Island (except gobiids), and, generally, on other islands in the Indian Ocean area (Maldives, Chagos, Madagascar and Christmas Island). The Gobiidae only represented 5.4% of the ichthyofauna, which was similar to the ratio for Aqaba (Red Sea), contrasting with 8.0% recorded for the Maldives, 13.0% at Chagos or other higher percentages recorded in the Pacific Ocean. The Apogonidae and Scaridae are relatively poorly diversified at Reunion, also in contrast with the Maldives, Madagascar, Chagos, Aqaba (Red Sea) and certain Pacific areas. The recent geological origins of Reunion Island and the low diversity of its marine biotopes are probably the most significant factors explaining both the total species richness and species richness of some major families.
L'ichtyofaune de l'île de La Réunion a été étudiée au cours de plusieurs travaux portant sur l'écologie des poissons et sur les pêcheries artisanales. Les informations issues de ces études, ainsi que d'autres sources, ont été compilées dans la présente liste des poissons marins de l'île. Un total de 885 espèces appartenant à 150 familles est recensé. Neuf espèces ne sont connues que de La Réunion, indiquant un endémisme proche de 1,0%. Les familles les plus diversifiées (Labridae, Gobiidae, Serranidae et Pomacentridae) sont aussi parmi les plus diversifiées à l'île Maurice voisine (à l'exception des Gobiidae), ainsi que dans d'autres îles de l'océan Indien (Maldives, Chagos, Madagascar et Christmas). Les Gobiidae ne représentent que 5,4% de l'ichtyofaune totale, ce qui est semblable à ce qui est connu à Aqaba (mer Rouge), mais contraste avec les 8,0% trouvés aux Maldives, les 13,0% trouvés aux Chagos ou d'autres pourcentages élevés dans l'océan Pacifique. Les Apogonidae et les Scaridae sont relativement peu diversifiés à La Réunion, ce qui contraste également avec ce qui est connu des Maldives, Madagascar, Chagos, la mer Rouge et certaines régions de l'océan Pacifique. Le jeune âge géologique de l'île et la faible diversité de ses biotopes marins pourraient être parmi les facteurs les plus importants pouvant expliquer la faible richesse spécifique totale et la richesse spécifique de certaines familles.
