Spatial behavior of two coral reef fishes within a Caribbean Marine Protected Area ArchiMer
Garcia, Jessica; Mourier, Johann; Lenfant, Philippe.
A better understanding of the key ecological processes of marine organisms is fundamental to improving design and effective implementation of marine protected areas (MPAs) and marine biodiversity. The movement behavior of coral reef fish is a complex mechanism that is highly linked to species life-history traits, predation risk and food resources. We used passive acoustic telemetry to study monthly, daily and hourly movement patterns and space use in two species, Schoolmaster snapper (Lutjanus apodus) and Stoplight parrotfish (Sparisoma viride). We investigated the spatial overlap between the two species and compared intra-specific spatial overlap between day and night. Presence-absence models showed different diel presence and habitat use patterns between...

Utilisation des données satellite pour la surveillance marine dans les Antilles ArchiMer
Huguet, Antoine.
Le traitement des données satellite permet d’établir des climatologies très longues souvent sur plusieurs dizaines d’années. Ces traitements fournissent des produits utilisables notamment dans le cadre de la réponse à la Directive Cadre sur l’Eau sur plusieurs indicateurs : transparence, température et biomasse. Leur utilisation a été largement étudiée en métropole et a donné des résultats intéressants. L’idée de les reprendre pour les DOMs semble encore plus pertinente du fait des séries temporelles in situ plus limitées. L’apport du satellite devrait donc permettre d’avoir des séries plus longues et d’apporter une vision globale à la surveillance de l’environnement côtier. Ce document, à destination de l'OFB, présente dans un premier temps les...

Techniques de pêche utilisées en Martinique pour l’exploitation des grands poissons pélagiques du large ArchiMer
Flament, Margaux; Monet, Nans; Pau, Cedric; Reynal, Lionel.
In the West Indies, artisanal vessels target pelagic fish off the coast using several fishing gears in the same trip, which complicates their codification based on ICCAT references. This paper describes the fishing techniques used in Martinique in exploiting offshore pelagic species. A distinction is made between two métiers, fishing for large pelagic species on free schools or around driftwood and fishing close to anchored fish aggregating devices. These two métiers can be used in the same trip. Fishers can also suspend their use to catch small offshore pelagic species such as flying fish. Each gear enables a species group to be targeted. However, data collection carried out at landing sites does not allow assignment of catches to each of the gears used...

Mise au point technique de l'élevage de l'ombrine Sciaenops ocellata à la Martinique ArchiMer
Soletchnik, Patrick; Goyard, Emmanuel; Thouard, Emmanuel.
Depuis maintenant plus de trois ans, l'équipe IFREMER de Martinique travaille à la mise au point technique de l'élevage de l'ombrine subtropicale (Sciaenosp ocellata), dans des conditions intensives. En matière de reproduction, l'équipe IFREMER a engagé dès 1987, une opération de transfert de la technologie Américaine de maturation et ponte grâce au contrôle environnemental de la température et de la phtopériode. Près de 50 millions d'oeufs ont été produits en 1989, à partir de 5 femelles de 5 à 6 kg. En terme d'alevinage, les "résidus d'expérimentation" ont été de 12 000, 18 000, 9 000 et 89 000 alevins sevrés (1 à 2g), respectivement pour les années 1987, 88, 89 et 1990. En 1990, l'objectif principal de démonstration de la faisabilité de la technique...

Premiers essais d'élevage larvaire de l'ombrine subtropicale (red fish) Sciaenops ocellatus dans les conditions intensives en Martinique ArchiMer
Soletchnik, Patrick; Thouard, Emmanuel; Goyard, Emmanuel; Baisnee, D; Yvon, C; Baker, P.
Two batches of red drum larvae were air shipped from hatcheries in the U.S.A. and stocked in two intensive tank experiments at densities oc 7 :.nd 2-3 larvae per liter. Food items include live rotifers, copepods, brine shrimps. squid and commercial fish pellets. Growth rates were similar in both experiments up to day 20 (12-1" mm) but differences in feeding schedules and an infestation by the dinoflagelate Amyloodinium sp. affected the growth from day 20 to 43 in the second trial. Significant mortalities occurred in the tanks during the first feeding period (days 2 to 7) and again from days 17 to 20 as the result of cannibalism. Survival between day 2 and day 44 was 44% in the first trial. Abnormal inflation of the swim bladder and infection with...

Blackfin tuna (Thunnus atlanticus) fishing around FADs in Martinique (French West Indies) ArchiMer
Taquet, Marc; Reynal, Lionel; Laurans, Martial; Lagin, Alain-sabin.
This paper examines the fishing of blackfin tuna (Thunnus atlanticus) around Fish Aggregating Devices (FADs) in Martinique (French West Indies). It is based on the compared analysis of catches from monthly experimental fishing surveys and sampling of commercial landings. The data collected in these two different ways allowed comparison of blackfin tuna length frequencies. A large part of the commercial landings were made up of young immature tuna with a fork length of less than 40 cm, whereas the experimental longline catches were mainly made up of fish with a fork length ranging between 55 and 75 cm. We give evidence that these discrepancies were mostly due to the fishing technique used. Indeed, contrarily to the experimental surveys, Martinican fishermen...

Traitement des données phytoplanctoniques et pigmentaires disponibles dans les DOMs. Analyse complémentaire des nouvelles données acquises et proposition de nouvelles acquisitions et approches complémentaires. Livrable 2 : rapport sur l’application de possibles indices phytoplanctoniques dans les DOMs à partir de l’analyse des données disponibles ; proposition de métriques et seuils. Rapport final ArchiMer
Gailhard-rocher, Isabelle; Artigas, Luis-felipe; Belin, Catherine; Lamoureux, Alice.
Le paramètre choisi pour l’évaluation de l’indice biomasse de l’élément de qualité phytoplancton est la chlorophylle-a, et la métrique utilisée est le percentile 90. Des grilles doivent être définies pour pouvoir assigner à chacune des masses d’eau la classe de qualité qui lui correspond du point de vue de cet indice. Différentes grilles, adaptées aux eaux très oligotrophes des trois départements outre mer que sont la Martinique, la Guadeloupe et La Réunion, ont été testées, et les résultats de ces simulations sont présentés ici. Les états des lieux initiaux et les études menées localement avaient déjà conduit à proposer des grilles. En Guadeloupe, les seuils provisoires retenus pour l'indice biomasse sont ceux initialement fixés à l’état des lieux de...

Un engraissement côtier résultant de l’érosion des bassins-versants cultivés : exemple de la baie du Galion à la Martinique ArchiMer
Saffache, P.
The progradation of the shores of the Gallon Bay (Martinique) has been measured based on diachronic mapping analysis. The sedimentary volume which accumulates along the coast and in the bay (under the water surface) is unknown. Erodibility has been surveyed on a square meter scale and extrapolated to the watersheds. The results show that most sediments originate from the farmed surfaces, they are then entrained by the runoff and the Gallon river and deposited along the coast, where the bathymetry and currentology of the bay facilitate sediment retention. The harmful effects of anthropogenic influence in the area are discussed.

Le Dispositif de Concentration de Poissons (DCP): une alternative à la forte pression de pêche sur les ressources récifales de la Martinique ArchiMer
Taquet, Marc.
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...

First records of the red lionfish (Pterois volitans) in Martinique, French West Indies: monitoring invasion status through visual surveys ArchiMer
Trégarot, Ewan; Fumaroli, Marine; Arqué, Alexandre; Helli, Claire; Maréchal, Jean-philippe.
The red lionfish (Pterois volitans) was first recorded in Martinique on 1 February 2011. Three years later, despite control measures to prevent the increase of lionfish population densities, the species is now well established. Maximum density has reached 1320 individuals ha−1 in some locations and the maximum fish size of 41 cm total length has been observed. A monitoring program was initiated by the Marine Institute of Martinique (OMMM) in 2011 to monitor the invasion and adjust local control efforts. Our results highlight how fast lionfish have been able to invade new littoral areas, especially hard bottom habitats. It took two years for them to completely colonize the west coast of Martinique, despite increasing capture efforts. It is expected that...
