| In the booming context of shrimp culture in French Caledonia, some research actions need to be considered in order (i) to make sure this production will not impact the quality and biodiversity of the coastal environment it is contingent upon (ii) for the field to highlight, based on objective bases, its good "environmental image", for an efficient commercialization of its products. In the framework of the MOM project, a number of actions have been carried out: Action 1: A bibliographical synthesis of the impact of shrimp culture on coastal environment has been conducted, taking into account the works carried out throughout the world and in French Caledonia in order to draw the main issues the Territory will have to deal with. It seems necessary to start... |

| En 1996, le vieillissement des fonds de bassins aquacoles de crevettes était présenté comme hypothèse explicative de la dégradation des rendements de production sur certains sites d’élevage. Un travail conséquent avait été réalisé à l’époque dont l'objectif était, à partir d'un inventaire des différents sédiments des fermes aquacoles du Territoire, de mettre en évidence une éventuelle évolution de ce sédiment au fil des cycles d'élevage et son influence sur la productivité. L’objet de ce document est de numériser et de compiler les différentes fiches techniques diffusées à l’époque sous forme papier aux aquaculteurs de la filière crevette de Nouvelle-Calédonie. |

| L’aquaculture de crevettes Litopeneus stylirostris, qui est apparue en 1970 en Nouvelle-Calédonie, est devenue une activité économique importante aujourd’hui avec 17 fermes en production et un tonnage de 2000 tonnes en 2004. Situées sur des zones d’arrière mangrove, les fermes exercent une pression sur l’environnement limitrophe, notamment les mangroves. Le rejet des eaux usées des fermes aquacoles dans le lagon semble constituer le principal impact sur l’environnement côtier. La présente étude qui a été lancée dans le cadre du programme ZoNéCo a pour principal objectif l’évaluation d’éventuels impacts de l’aquaculture sur les mangroves de Nouvelle-Calédonie. Elle s’attache : - d’une part à étudier l’évolution des différentes strates végétales d’une... |

| Les marais maritimes sont des espaces littoraux de niveau inférieur à celui des hautes mers de vive eau qui ont été structurés par l'homme dans les infrastructures côtières abritées (slikke, schorre). Ils représentent au total une superficie de 27000 hectares dans les régions Pays de Loire, Poitou-Charentes et Aquitaine dont 13 % sont endigués et en exploitation (Manaud et al, 1992). Dans le cadre de la revalorisation du marais, des activités aquacoles se sont développées au cours de ces quinze dernières années : la vénériculture, la pénéiculture et la pisciculture semi-intensive du bar (Dicentrarchus labrax) ou la daurade royale (Sparus aurata). Cette aquaculture nouvelle s'étend actuellement sur 300 hectares et aura produit 150 tonnes de poissons en... |

| In tropical shrimp ponds, the increasing of feed input, concomitantly with the stocking shrimp biomass, induces an eutrophication of the ecosystem. Although difficult to maintain, its stability is required to guarantee the success of the culture. A 110-day period of phytoplankton and bacterioplankton stock and dynamics in an earthen pond (1.2 ha area, 1 m depth) was monitored using flow cytometry to provide baseline information on community characteristics and ecosystem instability. Seven autotrophic cell types were identified over the whole sampling period. Prokaryotic cells included Synechococcus sp., a group named UNK which presented an atypical new flow cytometric signature and picoeukaryotes (PEUK). Nanophytoplankton cells were represented by 4... |

| La particularité des sols côtiers de Nouvelle-Calédonie est d’être essentiellement formés de latérites, exploitées depuis des décennies pour leurs teneurs en éléments traces métalliques (ETM) tels que le nickel, le chrome, le cobalt ou le manganèse. De par sa forte productivité en matière organique, la mangrove constitue un réservoir important de matière organique dissoute (MOD) qui peut être transportée vers l’Océan sur de grandes distances. Les observations menées soulèvent la question du rôle puit/source que joue la mangrove vis-à-vis de la dynamique des ETM à l’interface Terre-Mer à l’aval des massifs miniers de Nouvelle-Calédonie. Le projet TREMOR a ainsi, pour objectif d’apporter des éléments de réponses à cette question en s’appuyant sur les... |

| Shrimp aquaculture in New Caledonia is subject to seasonal mortalities during grow-out due to highly virulent Vibrio nigripulchritudo (Vn). To understand the mechanisms affecting shrimp resistance and leading to significant mortality, a shrimp ecophysiology and immunology survey was conducted on two farms, the first considered as a "control" farm (HC), the second affected by the disease (DF). Mortality observed during the survey at DF started 50 days after stocking and was typical of this disease. The main observations regarding shrimp were: (a) growth was not affected by the disease and was faster in the DF than in the HC pond; (b) disease did not affect one sex more than the other, or a specific part of the population in terms of weight; (c) the physical... |

| Penaeid shrimp reared in earthen ponds are exposed to sediment, which can, in some instances, induce a stress. In seawater, the osmoregulatory capacity (hyporegulation) is a useful tool to compare the physiological condition of shrimp exposed to various stressors. By keeping some shrimp in cages at different locations of a single pond heterogeneous in terms of sediment quality, it was possible, using osmotic pressure (OP), to identify some locations where the stress was maximum and some others where it was minimum. Simultaneously, sediment samples were taken and analysed in order to evaluate some physico-chemical parameters that could be related to the stress observed in the shrimps kept in the cages. This approach allowed to show a significant positive... |

| An experiment was conducted in six earthen ponds with 20 shrimps m(-2) Litopenaeus stylirostris (Stimpson) during the warm season in New Caledonia to study the dynamics of wastes in relation with water exchange rate (WER). The nitrogen budget was established, taking into account the different forms of nitrogen in the water, sediment, feed and shrimp. Data from a wide range of treatments applied in unreplicated ponds were treated using regression analysis to establish the relationship between WER and partial nitrogen budget, sediment characteristics and shrimp performance. To compare effluent quality between treatments during the season, data were analysed using the non-parametric sign test. The water outflow was characterized by a decrease in the... |

| Tropical shrimp aquaculture systems in New Caledonia regularly face major crises resulting from outbreaks of Vibrio infections. Ponds are highly dynamic and challenging environments and display a wide range of trophic conditions. In farms affected by vibriosis, phytoplankton biomass and composition are highly variable. These conditions may promote the development of harmful algae increasing shrimp susceptibility to bacterial infections. Phytoplankton compartment before and during mortality outbreaks was monitored at a shrimp farm that has been regularly and highly impacted by these diseases. Combining information from flow cytometry, microscopy, pigment and phylogenetic analysis, the presence of Picocyanobacteria, Prasinophyceae and Diatomophyceae were... |

| New Caledonian shrimp farming feasibility studies started in the mid-seventies. Today ca. 2000 tons of Litopenaeus stylirostris, introduced in 1978, are semi-intensively produced each year. Since fifteen years, production has been impacted by two seasonal vibriosis, the “Summer” syndrome caused by Vibrio nigripulchritudo in relation to pond bottom and water column quality, and the “Winter Syndrome” caused by Vibrio penaeicida in relation to drastic temperature drops . With the ambition of elucidating processes possibly leading to mortality outbreaks in ponds, Ifremer has been conducting a research program since 2003 under the DESANS project (2003-2006) and the present DEDUCTION project, equally funded by the South and North Provinces and by the Government... |
