| 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... |

| Technology for the culture of the pink shrimp Farfantepenaeus paulensis in low-cost cages and pen enclosures was developed together with artisanal fishermen of the Patos Lagoon estuary, southern Brazil. Although the production of postlarvae (PL) under laboratory conditions is well documented, survival and growth during the nursery phase cages and pen enclosures in the nature has not yet been analyzed. Therefore, the present study compared survival and growth of F. paulensis postlarvae reared either in cages or pens. Six cages (2.0 ´ 2.0 ´ 1.4 m) of PVC-coated polyester with a mesh size of 1.5 mm were stocked with 800 PL26 each. To assess the effect of the substrate, a 10 cm layer of sand was added to three of these cages to simulate a pen enclosure. No... |

| Depuis l’assec du canal d’alimentation en 2004 après le passage du cyclone Gafilo, on a constaté une augmentation massive de la densité d’Upogebia spinimanus au sein de la ferme de l’AQUALMA-Besalampy. En cas d’apparition d’une nouvelle maladie des crustacés, ce phénomène constituerait un grand risque en favorisant sa transmission chez les crevettes élevées, voire les consommateurs. Une nouvelle méthode d’approche installée par le laboratoire centrale de l’AQUALMA s’intéresse sur la prévention des risques de maladie liée à la biosécurité, en même temps des crevettes, des consommateurs et de l’environnement. Par conséquent, durant ce 5 mois de stage, des pratiques sur terrain et en laboratoire au moyen de différentes expériences à noter le suivi... |

| Se exponen los resultados del estudio de impacto ambiental llevado a cabo durante 3 años en la zona costera sur central del golfo de Guacanayabo. El estudio comprende la evaluación de la calidad de agua y de los sedimentos de las principales fuentes de abasto de la granja camaronera CALISUR y la zona costera adyacente. Los valores obtenidos de los análisis en agua y sedimentos de las áreas de estudios permitieron dar una valoración del estado ambiental de las zonas, revelando el no impacto de la granja camaronera en la zona costera, salvo en el sistema lagunar Las Playas, ecosistema muy deteriorado, dadas sus características como receptor directo de los residuales camaroneros por el sistema de producción de la granja. Según los datos... |

| It was evaluated different inclusion levels of carbohydrates (20, 25, 30 and 35%) on the performance of Pacific white shrimp fed isoprotein diets (33% crude protein) and isoenergy (4,700 kcal kg -1) diets in a complete randomized design with four treatments (n = 3). The experiment was performed in a pond with 1,200 m 2 and 1.5 m depth, where food intake, daily weight gain, feed conversion, protein efficiency ratio, and retention rates of crude protein and gross energy and survival rate of shrimp were evaluated. For the different inclusion levels of soluble carbohydrates, there were no differences for feed conversion, and retention rates of crude protein and gross energy and survival rate, resulting in means of 1.22:1, 1.2%, 0.74 and 95.0%, respectively.... |

| La ferme de l’AQUALAMA Besalampy est confrontée à un problème de mue des juvéniles de crevettes Penaeus monodon durant leurs transfert du bassin de pré-grossissement vers les bassins de grossissement. Le pourcentage des crevettes molles dépasse le seuil 10% durant la pêche. On est obligé alors d’arrêter le transfert et de le rapporter à un autre jour. L’arrêt fréquent du programme de transfert perturbe le planning déjà établi par la société. Afin d’essayer de trouver les raisons qui déclenchent spontanément la mue des juvéniles, on a effectué le suivi des paramètres physico-chimique de l’eau (pH, température, salinité, oxygène dissous, profondeur de l’eau, les marées, la gestion d’eau,…) durant l’élevage et durant le transfert. On a constaté alors que le... |

| Meiofauna abundance, biomass and individual size were studied in mangrove sediments subjected to shrimp farm effluents in New Caledonia. Two strategies were developed: i) meiofauna examination during the active (AP) and the non-active (NAP) periods of the farm in five mangrove stands characteristics of the mangrove zonation along this coastline, ii) meiofauna examination every two months during one year in the stand the closest to the pond (i.e. Avicennia marina). Thirteen taxonomic groups of meiofauna were identified, with nematodes and copepods being the most abundant ones. Meiofauna abundance and biomass increased from the land side to the sea side of the mangrove probably as a result of the increased length of tidal immersion. Abundance of total... |

| Sustainability in operations is a key consideration when discussing aquaculture’s current and future role in providing food and increasing coastal and rural employment and incomes, among other social benefits. An important problem from the economics point of view is how the economics point of view is how the externalities generated by aquaculture and those that the industry suffers are internalized. This paper extends the analysis reported in Martinez-Cordero and leung (2004) for a group of semi-intensive shrimp farms in Mexico. Modifications to the traditional Total Factor Productivity (TFP) and Technical Efficiency (TE) indicators are carried out in order to incorporate in the evaluation the environmental effects of aquacultural activities. In a... |

| Coastal tropical shrimp farming may impact the adjacent ecosystems through the release of large quantities of effluents rich in nutrients. In New Caledonia, mangroves are considered as a natural biofilter to reduce impacts on the surrounding World Heritage listed lagoon. Our main objective was to understand the influence of effluent discharge on the biogeochemistry of mangrove sediments. A monitoring of the physico-chemical parameters of mangrove sediments was carried out during a whole year, including active and non active periods of the farm. The parameters studied were: i) benthic primary production (Chl-a concentrations), ii) physico-chemical parameters of sediments (redox potential, pH, salinity, TOC, TN, TS, δ13C and δ15N), iii) concentrations of... |

| The shrimp Farfantepenaeus paulensis is considered a suitable species for culture in the Patos Lagoon estuary, southern Brazil, where its catch has been decreasing in the last few years. Considering the potential of estuarine areas for shrimp farming, the application of low-cost structures to culture shrimp, such as the pen enclosures, is being proposed as an alternative source of income for artisanal fishermen and farmers living near Patos Lagoon. From an economical standpoint, these alternative systems present several advantages over the traditional pond-based culture systems since land, water pumping and artificial aerations are not required, high natural productivity is available and inexpensive materials are employed in the construction of grow-out... |

| Abstract Shrimp farming has a great ecological, economic, and social importance in northeastern Brazil. Although the conventional farming system is widely used, biofloc technology (BFT) system has been developed to reduce environmental impacts and optimizing the production. Thus,the present study evaluated the technical efficiency of production cycles of Litopenaeus vannamei in conventional and BFT systems.We analyzed 48 production cycles in the conventional system in 2013 and 2014 and 9 cycles in the BFT system in 2014 through data envelopment analysis (DEA). The inputs corresponded to the population density (post-larvae m-2), amount of feed (kg ha-1 cycle-1), labor (man ha-1) and power supply (HP ha-1), whereas the yield (kg ha-1 cycle-1) was considered... |

| A simulation was conducted to determinate the impact caused by the combination of Litopenaeus vannamei respiratory rate (mg O2 shrimp-1 h-1), the behavior of SOTR (kg O2 h-1) of mechanical aerators as a function of salinity, as well as the oxygen consumption rate of the pond water and soil (mg O2 L-1 h-1) on the aeration of shrimp ponds (1, 10, 50 and 100 ha) stocked with different densities (10, 40 and 120 shrimp m-2), salinities (1, 13, 25 and 37 ppt), temperatures (20, 25 and 30°C), and shrimp wet weight (5, 10, 15 and 20 g). Results showed that under lower salinity, with larger shrimp, and higher stocking density, higher will be the quantity of required 2-HP aerators to keep dissolved oxygen over 50% saturation. In addition, under low salinity, with 5... |
