Assimilation of shrimp farm sediment by Holothuria scabra : a coupled fatty acid and stable isotope approach ArchiMer
Mathieu-resuge, Margaux; Le Grand, Fabienne; Schaal, Gauthier; Kraffe, Edouard; Lorrain, Anne; Letourneur, Yves; Lemonnier, Hugues; Benoît, Julie; Hochard, Sébastien.
Deposit-feeding sea cucumbers are efficient nutrient recyclers and have the potential to contribute to the limitation of organic matter load in polyculture or integrated aquaculture systems. Assessing how they assimilate organic matter originating from other farmed species is therefore important for the development of such multi-species farming systems. Here, a coupled stable isotope − fatty acid approach was used to characterize the assimilation of organic matter from shrimp (Penaeus stylirostris) farming by Holothuria scabra in an experimental culture system. H. scabra were reared in mesocosms on shrimp farming-originating sediment with and without additional food sources (maize and fish meals). Although fatty acid results did indicate that...

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...

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...

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...

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...

Effect of water exchange on effluent and sediment characteristics and on partial nitrogen budget in semi-intensive shrimp ponds in New Caledonia ArchiMer
Lemonnier, Hugues; Faninoz, Sebastien.
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...

Effects of blue shrimp Litopenaeus stylirostris and goldlined rabbitfish Siganus lineatus in mono- and polyculture on production and environmental conditions ArchiMer
Trung Cong, Luong; Lemonnier, Hugues; Hochard, Sebastien; Royer, Florence; Letourneur, Yves.
This study was conducted to compare the effects of shrimp and rabbitfish in mono- and polyculture stocked at high biomass on production and environmental conditions in a mesocosm system. Shrimp (14 g) and/or rabbitfish (19 g) were stocked in four treatments with different density but with the same total biomass (236 g m−2), including shrimp monoculture (SM) (17 shrimp m−2), shrimp–fish polyculture (SF) (11 shrimp and 4 rabbitfish m−2), fish–shrimp polyculture (FS) (6 shrimp and 8 rabbitfish m−2) and fish monoculture (FM) (12 rabbitfish m−2). After 10 weeks of experiment, shrimp survival and biomass were low in the treatments where shrimp were dominant (SM, SF), while rabbitfish survival and biomass were high in all the treatments. Shrimp mortality was...

Effet des conditions environnementales sur le développement des pathologies à Vibrio dans les élevages de crevettes en Nouvelle-Calédonie ArchiMer
Lemonnier, Hugues.
Shrimp aquaculture in New Caledonia is a developing industry, exclusively based on the species Litopenaeus stylirostris. However, it is subject to mortalities during grow out as observed all over the world. Since 1993, shrimp reared during the cold period are affected by a disease named "syndrome 93". As a consequence, the whole industry has become seasonal and produces essentially during the warm season. The climatic conditions during the periods of transition between the two main seasons could be responsible for an environmental stress and the origin reason for mortality outbreaks. Stocking density is the main risk factor. It increases the probability of the appearance and development of the epizooty in the pond. The "Summer Syndrome", a septicemic...

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...

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...

Evaluation de l’impact de l’aquaculture de crevettes sur les mangroves de Nouvelle-Calédonie ArchiMer
Virly, Sabrina; Buisson, Damien; Clough, Barry; Lemonnier, Hugues; Richer De Forges, Bertrand.
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...

Expériences sur l'influence des sédiments du bassin d'élevage sur la physiologie de Penaeus stylirostris. Rapport des travaux menés du 26 novembre au 7 décembre 1955 à la Station Saint Vincent ArchiMer
Cochard, Jean-claude; Goarant, Cyrille; Boglio, Eric; Lemonnier, Hugues.
The influence of the soil quality of culture pond on the physiological state of Penaeus stylirostris reared in earthen shrimp pond in New Caledonia was investigated by the measurement of the osmoregulatory capacity and magnesium hemolymph concentration of samples of 20 of these shrimp captured in the pond and maintained for 24 or 48h in cages laid on the bottom. A first experiment was affected by the occurrence of a pathology caused by Vibrio penaeicida probably due to initial handling stress. The second experiment showed that the osmoregulatory capacity is depresssed as a function of the soil quality : the more it is reduced the more the depression is important.

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....

Influence of sediment characteristics on shrimp physiology: pH as principal effect ArchiMer
Lemonnier, Hugues; Bernard, E; Boglio, E; Goarant, Cyrille; Cochard, Jean-claude.
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...
