| 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... |

| La première étude basée sur l’interprétation des données de la base Stylog‐module ferme, intitulée «Premières approches pour l’analyse de données d’élevages de crevettes marines en nouvelle Calédonie» a identifié de possibles indicateurs de productivité (Frappier et al., 2008). L’objectif du travail présenté ici vise à identifier les conditions zootechniques et environnementales ayant abouti aux meilleures performances. Ceci a été rendu possible par la mise au point d’une méthode de caractérisation des conditions dans lesquelles se sont déroulées les bons élevages, eux même identifiés par une méthode standardisée (scripts développés en langage R). L’étude des arbres de décision visant à caractériser les bons élevages en termes de productivité a permis... |

| Cette fiche biotechnique présente deux expérimentations visant à réduire voire substituer l'usage de l'érythromycine en élevage larvaire de Litopenaeus stylirostris. La première testant la bactérie Roseobacter gallaeciensis comme probiotique, associée ou non à des changements d'eau différents, n'a pas donné de résultats positifs malgré des résultats intéressants de croissance et de survie, obtenus sur des larves de mollusques au Laboratoire de Physiologie des Invertébrés de L'IFREMER de Brest. La méthode de culture de cette bactérie en algues axéniques n'avait pas été reproduite au LAC et devra certainement être prise en compte dans la perspective d'un autre essai. La deuxième expérimentation testait deux souches bactériennes locales comme probiotiques... |

| Shrimp farming in New Caledonia relies on the culture of a domesticated strain of Litopenaeus stylirostris introduced from Mexico at a time when genetic principles were of little or no consideration. Since then, advances in agriculture and for some aquatic species of importance led caledonian shrimp farmers to reconsider the appropriateness of a genetic improvement strategy adapted to local biotechnical and economical constraints. This questioning involves many different and interrelated aspects: scientific and technologic (genetics, biosecurity, quarantine, ), economic and organizational (financing, diffusion of genetic improvement) and pedagogic (awareness of farmers). Local institutions, producers associations, research centre and sanitary services... |

| Penaeus stylirostris shrimp imported from Hawaii for a genetic program and kept at the Saint-Vincent research facility had progressively developed a high sensitivity to IHHNV, the etiological agent of the Infectious, Hypodermic, and Hematopoietic Necrosis. Fears were that the virus could not only be transferred to their offspring, but also that the New Caledonian strain of Penaeus stylirostris, so far considered as resistant, could become sensitive by an off balance of its hosts/pathogen equilibrium. In October 2008, a joint decision between Uprac (shimp owner), Davar (New Caledonian Animal Health Authority) and Ifremer (scientific partner) was taken to terminate all pure breed and hybrid Hawaiian populations remaining in the ponds, and to implement an... |

| Two recurring syndromes threaten the viability of the shrimp industry in New Caledonia, which represents the second largest export business. The "Syndrome 93" is a cold season disease due to Vibrio penaeicida affecting all shrimp farms, while the "Summer Syndrome" is a geographically restricted vibriosis caused by a virulent lineage of Vibrio nigripulchritudo. Microbiological procedures for diagnosis of these diseases are time-consuming and do not have the ability to discriminate the range of virulence potentials of V. nigripulchritudo. In this study, we developed a multiplex PCR method to simultaneously detect these two bacterial species and allow for pathotype discrimination. The detection limits of this assay, that includes an internal amplification... |

| Ce document constitue le bilan détaillé des résultats du projet DEDUCTION (2007-2010) , action par action. Le projet DEDUCTION "DEveloppement DUrable de la Crevetticulture, Traitement de l’Information et Observatoire du système en Nouvelle-Calédonie" est un projet de recherche et de développement en soutien à la filière crevetticole néo-calédonienne. C'est un programme très horizontal et pluridisciplinaire en poursuivant et développant les ouvertures scientifiques, techniques et thématiques établies à la faveur de DESANS. Son ossature s’articule autour de 4 actions : 3 actions de recherche et une action transversale devant faciliter les interfaces entre la recherche et sa finalité, entre les chercheurs et les partenaires locaux (GFA, Provinces,... |

| In order to have a standardised database gathering most information on New Caledonian prawn farms a software, called “Stylog-module ferme”, was developed and implemented by Ifremer with the help of shrimp farmers. Data recording results in more than 2 million data from 250 crops since the beginning of the project (2003). The main objective is to help the researchers in understanding the processes taking place in a cultured pond. It also provides a follow-up of the prawn farming industry (evolution of management practices, health surveillance system…) and to facilitate sharing of information between the different partners of the industry (prawn farmers, research and local authorities). Finally, this decision-making tool also helps shrimp farmers for routine... |

| The Summer Syndrome is a new shrimp disease that has been affecting a shrimp growout farm in New Caledonia since end of 1997. It was recognized to be caused by a systemic vibriosis due to Vibrio nigripulchritudo. This new disease turned out almost immediately enzootic in the shrimp farm involved and has affected all its crops ever since. Since the year 2000, V. nigripulchritudo strains have been found in several shrimp farms, although Summer Syndrome is still limited to one particular area, affecting, since 2003, two adjoining farms. As part of a multidisciplinary research program, a high-frequency survey was carried out during the summer 2002-2003 in two shrimp farms: one affected farm and another one in which pathogenic strains could be isolated but... |

| Vibriosis is a major disease problem in shrimp aquaculture. 'Syndrome 93' is a seasonal juvenile vibriosis caused by Vibrio penaeicida which affects Litopenaeus stylirostris in grow-out ponds in New Caledonia. This study assessed the toxic activities of extracellular products (ECPs) from V: penaeicida, V. alginolyticus and V, nigripulchritudo using in vivo injections in healthy juvenile L. stylirostris (= Penaeus stylirostris) and in vitro assays on shrimp primary cell cultures and the fish cell line epithelioma papulosum cyprini (EPC). Toxic effects of ECPs were demonstrated for all pathogenic Vibrio strains tested both in vivo and in vitro, but for shrimp only; no effect was observed on the fish cell line. ECP toxicity for New Caledonian V. penaeicida... |
