Beliaeff, Benoit; Chim, Liet; Della Patrona, Luc; Goyard, Emmanuel; Herlin, Jose; Labreuche, Yannick; Walling, Emilie; Ansquer, Dominique; Brun, Pierre; Castex, Mathieu; Coatanea, Denis; Courties, Claude; De Lorgeril, Julien; Dufour, Robert; Frappier, Julie; Goarant, Cyrille; Huber, Matthias; Lemaire, Pierrette; Lemonnier, Hugues; Loubersac, Lionel; Le Roux, Frederique; Lucas, Ronan; Patrois, Jacques; Peignon, Jean-marie; Pham, Dominique; Ramage, Yannick; Soulard, Benoit; Vic, Marlene; Vourey, Elodie; Wabete, Nelly.
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...

Diagenetic Processes in Aquaculture Ponds Showing Metal Accumulation on Shrimp Gills ArchiMer
Lemonnier, Hugues; Royer, Florence; Caradec, Florian; Lopez, Etienne; Hubert, Clarisse; Rabiller, Emilie; Desclaux, Terence; Fernandez, Jean-michel; Andrieux-loyer, Francoise.
The gill is the organ by which many toxic metals are taken up by crustaceans. Iron is known to precipitate at its surface, a phenomenon recently observed in some tropical aquaculture ponds. The present study uses a field approach to understand better the environmental conditions and ecological processes involved in this deposit. Because shrimp are exposed to reduced products originating from organic waste accumulated in the sediment, spatial variation in pH, redox potential and concentrations of dissolved metals in pore water were investigated in these ponds. Total organic carbon, acid volatile sulfide and pyrite were also analyzed in the solid phase. Fe2+ in pore waters showed high spatial variability between ponds and within the same pond with...

Spatial and temporal extension of eutrophication associated with shrimp farm wastewater discharges in the New Caledonia lagoon ArchiMer
Thomas, Yoann; Courties, Claude; El Helwe, Yasmin; Herbland, Alain; Lemonnier, Hugues.
Shrimp farming in New Caledonia typically uses a flow-through system with water exchange rates as a tool to maintain optimum hydrological and biological parameters for the crop. Moreover, the effluent shows hydrobiological characteristics (minerals, phytoplankton biomass and organic matter) significantly higher than that of the receiving environment. Separate surveys were carried out in a bay (CH Bay) with a medium-size intensive farm (30 ha) (PO) and in a mangrove-lined creek (TE Creek) near a larger semi-intensive farm (133 ha) (SO). Net loads of nitrogen exported from the semi-intensive farm and the intensive farm amounted to 0.68 and 1.36 kg ha(-1) day(-1), respectively. At CH Bay, discharge effects were spatially limited and clearly restricted to...

Caractérisation des sédiments des fonds de bassin des différentes fermes aquacoles de Nouvelle- Calédonie : Compilation des fiches techniques publiées de 1998 à 2000 ArchiMer
Lemonnier, Hugues.
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.

Combined effect of exposure to ammonia and hypoxia on the blue shrimp Litopenaeus stylirostris survival and physiological response in relation to molt stage ArchiMer
Mugnier, Chantal; Zipper, Etienne; Goarant, Cyrille; Lemonnier, Hugues.
The effect of ambient ammonia, hypoxia and combination of both on survival and the physiological and immunological response of the blue shrimp Litopenaeus stylirostris in relation to molt stage was studied. Shrimp were submitted to 44.0-71.5 mg 1(-1) total ammonia-N corresponding to 2.0 mg 1(-1) unionized ammonia NH3-N and/or to 1.5 mg O-2 1(-1) (4.3 kPa) for 24 hours. Survival was recorded and the molt stages of both dead and surviving shrimp determined. Only shrimp in intermolt and premolt stages were sampled for analysis of haemolymph. Haemolymph was assayed for osmoregulatory capacity (OC), magnesium ion (Mg2+), calcium ion (Ca2+), total proteins, oxyhaemocyanin, lactate, glucose and total haemocyte count (THC). Low mortalities were recorded for...

Nutrient and microbial dynamics in eutrophying shrimp ponds affected or unaffected by vibriosis ArchiMer
Lemonnier, Hugues; Courties, Claude; Mugnier, Chantal; Torreton, Jean-pascal; Herbland, Alain.
A field survey was conducted on two intensive shrimp farms using similar technical practices: one (DF) historically affected by a vibriosis, the other (HC) in which the pathogen has been observed although no mortality event has occurred. Because historical data suggest that eutrophication process may directly or indirectly play a role in the disease outbreak, we focussed our research on its dynamics. A higher variability of the phytoplanktonic compartment linked to an imbalance in the molar N:P ratio was observed in farm DF compared to farm HC, implying a modification on the linkage between the bacteria and phytoplankton compartments at DF. The beginning of the mortality outbreak at DF followed a shift from picoto nanophytoplankton. The organic matter...

SEARSÉ (volet 1) Signature des eaux des rivières et des estuaires dans le sud-ouest de la Nouvelle-Calédonie ArchiMer
Lemonnier, Hugues; Royer, Florence; Lopez, Etienne; Berne, Stéphanie; Boher, Laura; Coignot, Elise; Desnues, Anne; Dupouy, Cécile; Helly, Maëlle; Gérard, Philippe; Gunkel-grillon, Peggy; Jamet, Léocadie; Lemestre, Monica; Liufau, Félise; Siano, Raffaele; Soulard, Benoit.
De par des mutations économiques, démographiques et sociétales, que connaît à ce jour la Nouvelle-Calédonie, des pressions anthropiques ne cessent de croître sur les milieux littoraux et côtiers. Les rivières sont d’importants vecteurs de transport de sédiments et d’éléments dissous. Ces apports, s’ils sont essentiels pour le fonctionnement des écosystèmes côtiers, peuvent être néfastes en cas d’excès (sels nutritifs, métaux et autres contaminants). Le projet SEARSE a pour objectifs de qualifier et de quantifier les apports des rivières et suivre leur devenir dans les panaches dans le lagon autour du grand Nouméa.

Monitoring mangrove forests after aquaculture abandonment using time series of very high spatial resolution satellite images: A case study from the Perancak estuary, Bali, Indonesia ArchiMer
Proisy, Christophe; Viennois, Gaelle; Sidik, Frida; Andayani, Ariani; Enright, James Anthony; Guitet, Stephan; Gusmawati, Niken; Lemonnier, Hugues; Muthusankar, Gowrappan; Olagoke, Adewole; Prosperi, Juliana; Rahmania, Rinny; Ricout, Anais; Soulard, Benoit; Suhardjono,.
Revegetation of abandoned aquaculture regions should be a priority for any integrated coastal zone management (ICZM). This paper examines the potential of a matchless time series of 20 very high spatial resolution (VHSR) optical satellite images acquired for mapping trends in the evolution of mangrove forests from 2001 to 2015 in an estuary fragmented into aquaculture ponds. Evolution of mangrove extent was quantified through robust multitemporal analysis based on supervised image classification. Results indicated that mangroves are expanding inside and outside ponds and over pond dykes. However, the yearly expansion rate of vegetation cover greatly varied between replanted ponds. Ground truthing showed that only Rhizophora species had been planted,...

TREMOR ( Volet 1) Transfert des éléments traces métalliques par la matière organique dissoute colorée ArchiMer
Dupouy, Cécile; Juillot, Farid; Lemonnier, Hugues; Mounier, Stéphane; Boher, Laura; Bessard, Marie; Jamet, Léocadie; Gérard, Philippe; Gunkel-grillon, Peggy.
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...

Feasibility of polyculture of blue shrimp Litopenaeus stylirostris and goldlined rabbitfish Siganus lineatus in a mesocosm system ArchiMer
Luong, Trung Cong; Hochard, Sebastien; Royer, Florence; Lemonnier, Hugues; Letourneur, Yves.
The study was conducted to (1) estimate the effects of polyculture of blue shrimp Litopenaeus stylirostris with goldlined rabbitfish Siganus lineatus on production, environmental quality and water and sediment metabolism and (2) to determine if blue shrimp and goldlined rabbitfish polyculture is possible. The experiment was carried out for 12 weeks in a mesocosm system that consisted of 12 circular outdoor mesocosm fiberglass tanks (1.7 m2, 1275 L water volume). Shrimp (2.9 g) were randomly stocked at density of 15 shrimp.m− 2 without rabbitfish (control), with rabbitfish (25.5 g) at low density (1.2 fish.m− 2) (LDRB) and high density (2.4 fish.m− 2) (HDRB). Results indicated that goldlined rabbitfish S. lineatus did not affect shrimp growth performance....

Dynamics of phytoplankton communities in eutrophying tropical shrimp ponds affected by vibriosis ArchiMer
Lemonnier, Hugues; Lantoine, Francois; Courties, Claude; Guillebault, Delphine; Nezan, Elisabeth; Chomerat, Nicolas; Escoubeyrou, Karine; Galinie, Christian; Blockmans, Bernard; Laugier, Thierry.
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...

Eutrophication in a tropical pond: Understanding the bacterioplankton and phytoplankton dynamics during a vibriosis outbreak using flow cytometric analyses ArchiMer
Lucas, Ronan; Courties, C.; Herbland, Alain; Goulletquer, Philippe; Marteau, Anne-laure; Lemonnier, Hugues.
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...

Biological, physiological, immunological and nutritional assessment of farm-reared Litopenaeus stylirostris shrimp affected or unaffected by vibriosis ArchiMer
Mugnier, Chantal; Justou, Carole; Lemonnier, Hugues; Patrois, Jacques; Ansquer, Dominique; Goarant, Cyrille; Le Coz, Jean-rene.
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...

Desclaux, Terence; Pischedda, Marine; Lemonnier, Hugues; Soulard, Benoit; Le Gendre, Romain.
Ce rapport fait suite au stage de Marine Pischedda (Master 2 La Rochelle) réalisé au sein de l’unité de recherche "Lagons, Ecosystèmes et Aquaculture Durable en Nouvelle-Calédonie" (LEAD/NC) de l’Ifremer entre février et juillet 2016. Cette étude a été conduite sur quatre bassins versants du Grand Nouméa : la Coulée, la Dumbéa Est, la Dumbéa Nord et la Couvelée. L’objectif principal était de démontrer la pertinence de l’utilisation de modèle pluie-débit au pas de temps horaire (GR4H en l’occurrence) sur les bassins versants calédoniens. Le cadre plus général de ce travail était d’aboutir à une représentation affinée du continuum terre-mer par le couplage des modèles GR4H et MARS3D développés pour simuler la circulation côtière. Les périodes d’étiages ayant...

Effets des renouvellements en eau sur l'écosystème des bassins d'élevages semi-intensifs de crevettes en Nouvelle-Calédonie durant la saison froide ArchiMer
Lemonnier, Hugues; Brizard, Raphael.
Une expérience a été réalisée en conditions hivernales dans six bassins de terre pour déterminer l'effet des taux de renouvellement sur la production de crevettes Penaeus stylirostris, sur les caractéristiques de l'eau et du sédiment des enceintes d'élevage. Les budgets d'azote ont été établis en prenant en compte les différentes formes azotées dans l'eau, dans le sédiment, dans l'aliment et dans les crevettes. Un épisode de mortalité a été obserVé en cours d'élevage et peut être attribué à une epizootie dénommée "syndrome 93». Ce dernier était concomitant à une phase de croissance phytoplantonique et a été d'autant plus important que la biomasse phytoplanctonique dans le bassin d'élevage était élevée. Bien qu'une dilution importante de la colonne d'eau se...
