It is estimated that fish aggregating devices (FADs) are now used for over 40% of world tropical tuna catches, making this technique a major phenomenon for high seas fisheries worldwide, and one that has experienced great expansion over the past three decades. The question of whether the FAD is a good or a bad tool for the exploitation of marine resources depends on many parameters. To respond to this question, it is necessary to distinguish different scales of exploitation (artisanal vs. industrial) and various types of FADs (anchored vs. drifting), but it is also very important to gather more data and conduct further research on this topic to gain a better understanding of the phenomenon and of its impacts. As such, twelve years after the first... |

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... |

Automated acoustic receivers are now widely used by biologists to study the behavior of fish. However, currently available acoustic receivers require physical recovery of the units to download stored data. Such operation is often difficult in remote study areas like in the open ocean. We present a new satellite-linked acoustic receiver (Vemco VR3-Argos) that allows downloading data through a satellite uplink (Argos). The VR3-Argos can last up to one year, sending GPS positions and tag data at regular time intervals. We illustrate the advantages of this new technology with tagging data from 121 fish of seven species (yellowfin tuna, bigeye tuna, skipjack tuna, wahoo, dolphinfish, silky shark and oceanic triggerfish) caught and released around drifting fish... |

This paper describes the fishing activity in Martinique, French West Indies. It draws up the balance sheet of acquirements about marine resources of the island. The difficulties of fisheries management are discussed with reference to biologists and economists works in the last ten years. We also show how management efforts to decrease fishing pressure on reef resources has induced the implantation of a new technology: the Fish Aggregating Deviee. The differing histories of development of FADs in the French West Indies are compared. The positive results from the introduction of the FADs and the estimated risks due to the transferance of fishing pressure on the continental shelf is presented. The use of FADs to enhance the exploitation of marine resources is... |

Fishing with a beach seine for catching small pelagic fishes is a traditional activity in Martinique. Since the early eighties, an important decrease in the number of fishermen practising this activity has been recorded. In the context of high exploitation of reef resources, the beach seine presents a low selectivity, catching too many juveniles of demersal fish. The fads established in coastal areas, have been successfully used in others regions of the world for exploiting small pelagics. Thus, it could allow to favour a change of exploitation style of these resources in Martinique. In partnership, Ifremer, the Regional Council and the Fishing Committee have began an evaluation of the potentialities for this type of structures around the island. To... |

Commercial longline fishing data were analyzed and experiments were conducted with gear equipped with hook timers and time-depth recorders in the Reunion Island fishery (21 degrees 5'S lat., 53 degrees 28'E long.) to elucidate direct and indirect effects of the lunar cycle and other operational factors that affect catch rates, catch composition, fish behavior, capture time, and fish survival. Logbook data from 1998 through 2000, comprising 2009 sets, indicated that swordfish (Xiphias gladius) catch-per unit of effort (CPUE) increased during the first and last quarter of the lunar phase, whereas albacore (Thunnus alalunga) CPUE was highest during the full moon. Swordfish were caught rapidly after the longline was set and, like bigeye tuna (Thunnus obesus),... |

The follow-up of the activity of the boats practising offshore fishing in the North-West of the La Réunion Cbaies of the Possession and Paul Saint) was carried out over one year(April 86 - March 87) thanks to the application of a strategy of sampling allowing the collection of the following statistics: total effort and by machine, captures total and by species.The study allowed a first approach of the space-time distribution of the activity of the fleet. It reveals the very high participation of the yachtmen in the halieutic exploitation of the studied sector. It also highlights the importance of tunas in the captures, which in weight are largely majority. |

Daily growth increments measured in the otolith of Thunnus atlanticus were used to estimate the age and growth of individuals. which were sampled from an artisanal fishery operating around fish aggregating devices (FADs) moored off Martinique Island. In this study, 76 otoliths were analysed for fish ranging from 20 to 68 cm fork lengths (FL). The fish were caught using trolling lines at depths ranging from 0 to 10 m. Counts were made, under a light microscope, on the external part of the transverse section of the sagittae, from the primordium to the ventral edge. The mean coefficient of variation of the age reading was 2.4%. To validate readings, the number of increments for 11 individuals was counted using both optic and scanning electron microscopes. The... |

Monitoring the abundance of green turtles (Chelonia mydas) is necessary to assess population trends and risks of collapse. This note presents a study aimed at comparing three techniques for the direct estimation of green turtle numbers in their foraging habitats (seagrass beds and reef flats). The experiment was carried out at Mayotte Island, Western Indian Ocean. The techniques involved were surveys by snorkel, and aerial surveys using a microlight aircraft and a paramotor. Each technique had shortcomings and advantages. While each technique provided estimations of turtle numbers only surveys by snorkel permitted identification of species and sex, whenever visibility and turtle behaviour permitted. Along the shorelines, and over foraging areas, the... |

Data on the potential exploitation of deep demersal fish species in Reunion Island are very limited. The Regional Comitee for Sea Fisheries and Marine Breeding, with the scientific and technical support of Ifremer of La Reunion, has launched prospecting campaigns to identify and characterize deep-sea fish species (between 150 to 600 m deep), with an innovative method of catching with electric reel. The catches made concern mainly 5 main species (yields, frequency of catch, commercial interest). A new species, the brillant pomfret (Eumegistus illustris), as well as the longtail red snapper (Etelis coruscans), are the both main resources that can be exploited by the electric reel technique. They represent more than 60% of the overall catches made during the... |

Contrary to the situation in Europe, Réunion Island is the only French department whose fishing has increased considerably for five years, as far as artisanal fishing linked to DCPs (Fish Concentration Plans), but also semi-industrial longline fishing and industrial fishing in southern oceans are concerned. Two capital events contribute to the quick development of tuna fishing and provide Reunion Island with access to its pelagic resources. The setting up in 1988 of the first DCPs by the French Research institute for the exploitation of the sea (Ifremer) resulted in a real upheaval of artisanal fishery and relaunched a sector which had been slowing down since 1980. In 1991, witnessing the success of Asian longline boats unloading on Reunion Island, a local... |

The authors deal with the coastal fisheries in the Reunion Island. In a first chapter they describe the geographical environment of this island (volcanism, climate, cyclones, hydrology, currents water masses) which has an influence on fisheries results. The second and third chapter describe the commercial species of the Reunion island (pelagic fishes: Scombridae as Thunnus albacares, Katsunonus pelamis, Euthynnus affinis, Thunnus obesus, Gymnosarda unicolor, Thunnus alalunga, other fishes as Xiphias gladius, Makaira mazara, Istiophorus platypterus. The fourth chapter deals with the fishing gears and the catching methods. The fifth chapter is devoted to fishery economics, financing |

This work presents a methodological synthesis for the in situ monitoring of fish aggregating devices (FADs) using a combination of optical, echosounder and SCUBA observations conducted in the vicinity of drifting FADs. The acoustic methods allowed, according to the devices used, the description of the spatial organisation and dynamics of biotic scattering layers, individual fishes, schools, shoals and mammals, while visual, photographic and video observations permitted species identification within a range of 0 to ~ 25 m. Based on these results, we elaborate on the interest to combine acoustic and visual methods, and present an autonomous instrumented drifting buoy for remotely monitoring fish diversity and abundance in the pelagic ecosystems. The... |
