| Ce document constitue le rapport final rendant compte des travaux réalisés dans le cadre de la convention n°8.033/MPA/SPE du 2 décembre 2008 modifiée et à l’avenant n° 0680 du 2 février 2011 entre l’Ifremer et le ministère des ressources marines de Polynésie Française. Il est mené en collaboration avec le Service de la Pêche de Polynésie (SPE). L’objet de cette convention était : la définition d’un protocole d’abattage et de conditionnement du Paraha peue (Platax orbicularis) d’élevage. Les travaux étaient centrés sur la recherche de la meilleure qualité du poisson et de l’évaluation de son évolution au cours de son stockage en vue du développement de sa filière aquacole en milieu insulaire tropical. Les différentes voies de traitement du produit péri... |

| Le polder conchylicole de Bouin (Vendée) est le principal bassin français de production de naissains d’huîtres creuses issus d’écloseries. Depuis 2007, et malgré l’installation de dispositifs de traitement de l’eau, des anomalies dans les élevages voire des mortalités affectent la production des écloseries et nurseries du secteur, ainsi que celle de microalgues en grand volume d'une entreprise spécialisée. Les observations des professionnels orientent la recherche de la cause de ces mortalités sur les contaminants chimiques, notamment les pesticides utilisés par l'agriculture, dont les exploitations du polder agricole, qui jouxtent le polder conchylicole. Comme l'ont montré de nombreux travaux, certains de ces produits altèrent la qualité de l’eau de mer... |

| Because of its rapid growth, its good reputation and the promising aquaculture experiences conducted in Norway and Scotland, cod is considered as a good candidate for cold water aquaculture. The aim of this paper is to present the work carried out in France since 1999: the selection of cod as a promising candidate for aquaculture and the assessment of its rearing performances in this environment. |

| Mimesis is a relatively widespread phenomenon among reef fish, but the ontogenetic processes relevant for mimetic associations in fish are still poorly understood. In the present study, the allometric growth of two allopatric leaf-mimetic species of ephippid fishes, Chaetodipterus faber from the Atlantic and Platax orbicularis from the Indo-Pacific, was analyzed using ten morphological variables. The development of fins was considered owing to the importance of these structures for mimetic behaviors during early life stages. Despite the anatomical and behavioral similarities in both juvenile and adult stages, C. faber and P. orbicularis showed distinct patterns of growth. The overall shape of C. faber transforms from a rounded-shape in mimetic juveniles to... |

| Marine fish farms use many antibacterial agents to prevent or fight bacterial diseases. The major part of the orally supplied drugs reach the environment, either directly due to excessive feeding and reduced appetite of the cultured fish, or indirectly after passing through the fish. Some of the drugs entering the environment may be taken up by bivalves. Comparative contamination and decontamination of Japanese oyster Crassostrea gigas and blue mussel Mytilus edulis were studied when these bivalves were kept during 10 d in seawater containing oxytetracycline (OTC) or oxolinic acid (OA) at concentrations of 0.15 and 1.50 mg l(-1). After the 10 d exposure at the seawater concentrations of 0.15 and 1.50 mg l(-1), OTC and OA concentrations in bivalve tissues... |

| Artificial insemination mastery in red drum, Sciaenops ocellatus, requires a first experimental step wOOng at getting basic biological data. Regarding males, a relation between optical density of the solution (OD) measured by spectrophotometry and sperm concentration (SC) has been established : OD O,161*SC + 0,119. Mean sperm concentration measured is 4,36.10 10 spz.mL-1. This study shows an influence of the solution of dilution on spermatozoa motility and its evolution during short term preservation. As far as females are concemed, the follow-up of final maturation through the observation of samples taken during reguIar strippings, seems to he a good technique to limit overripening and spontaneous liheration of ovules. Some artificial insemination trials... |

| Les missions réalisées fin 2004 et début 2005 ont permis de faire le point sur les coopérations potentielles entre l'INSTM et l'IFREMER. Un certain nombre de domaines de coopération et de sujets de collaboration ont été identifiés et se sont traduits (ou se traduiront) par des actions de coopération (missions, stages, formations) soutenues financièrement par le SCAC de l'Ambassade de France à Tunis. La coopération entre l'IFREMER et l'INSTM dans le domaine de l'aquaculture a été très active dans le cadre du programme« Aquaculture 2001 » (1997-2001). Depuis cette période les relations se sont limitées à la préparation du programme DORAD qui était la suite d' «Aquaculture 2001 » . En l'absence du financement FSP sollicité pour DORAD, les deux organismes ont... |

| L'eau qui alimente des structures d’élevage ou encore des plateformes expérimentales aquacoles (et potentiellement l’eau qui en est issue) peut être contaminée par des agents pathogènes infectant les coquillages, et plus particulièrement les huîtres, ou encore par des agents pathogènes entériques représentant un risque pour les consommateurs. Par ailleurs, la production possible d'huîtres tétraploïdes dans les installations d’élevage implique l’étude de solutions de traitement adaptées pour éviter tout rejet de gamètes, larves ou naissain d’animaux polyploïdes dans l'environnement. Le projet DESIMER a donc pour objectif d’étudier et de comparer différentes techniques de désinfection de l’eau de mer : la chloration, l’ozonation et le rayonnement UV afin de... |

| The uptake and elimination of six PBDE congeners (BDE-28, -47, -99, -100, -153, -209) were studied in juvenile common sole (Solea solea L) exposed to spiked contaminated food over a three-month period, then depurated over a five-month period. The results show that all of the studied PBDEs accumulate in fish tissues, including the higher brominated congener BDE-209. Several additional PBDE congeners were identified in the tissues of exposed fish, revealing PBDE transformation, mainly via debromination. The identified congeners originating from PBDE debromination include BDE-49 and BDE-202 and a series of unidentified tetra-, penta-, and hepta- BDEs. Contaminant assimilation efficiencies (AEs) were related to their hydrophobicity (log K-ow) and influenced by... |

| Red drum larvae were fed from day 11 to day 24 post-hatch, with Artemia (LP group) or two isoproteinic-formulated diets with varying lipid levels, 15% (L15 group) and 30% (L30 group). The lipid fraction was composed of a mixture of cod liver oil and soy lecithin. Larvae fed Artemia exhibited the greatest length, L30 diet induced a larvae length significantly greater than that obtained with L15 diet (P < 0,05). No difference was observed in larvae survival among the three dietary groups. The increase in dietary lipid concentration led to an increase in amylase and trypsin secretion levels in 24-day-old larvae. The pancreatic secretion level measured in L30 group was close to that of LP group, suggesting that the maturation of the pancreatic functions was... |

| Growth of juvenile pollack was assessed at five constant temperatures (9, 12, 15, 18 and 21 degrees C) in an 84-day trial. Duplicate groups of 75 fish (initial weight 143 +/- 2 g) were held in O-2 saturated water (102-103% saturation) and fed to apparent satiation. Growth increased as temperature increased from 9 degrees C up to a plateau at 12-15 degrees C (NS differences between 12 and 15 degrees C) followed by a decrease from 18 degrees C. No growth occurred at 21 degrees C. For the overall period, specific growth rates were 0.52% and 0.53% day(-1) at 12 and 15 degrees C compared to 0.40% day(-1) at 18 degrees C. Feed intake was maximum at 15-18 degrees C (0.68-0.69% day(-1)) and it was significantly lower at 21 degrees C (0.45% day(-1)). Apparent feed... |

| Whatever the hydraulic gestion, an épuration of the fishes sewages is possible with the integrated system studied. The main action is situed in the intermediary pond with a significant decrease of nutrients, especially ammonia, and particulate mineral matters. The oyster's pond have no significant action on nutrients, but their action is real on chlorophyll which become limiting factor in 20% renewal system. One of the effluent, system 1 (renewal 10%) had high suspended matter and low nutrient concentrations. The other (renewal 20%) was poor in supcnded matters (chlorophyll). The system 2 give best oyster's growth, close to traditional nursery performances, with an highest mortality (32%). In the first system, suspended matter concentrations are too high... |

| The pollack Pollachius pollachius is a commercially important fish, considered as a candidate for aquaculture in France. Rearing attempts are promising (Suquet et al., 1996), and more information is required about its reproduction, to contribute to a better management of breeders for this species. This study was designed to examine the first maturity in pollack and the effects of conditions such as origin and delayed reproduction season, on gonad maturation, reproductive and growth performances of adults. |

| Oysters, being filter feeders, can accumulate some human pathogens such as norovirus, a highly infectious calicivirus, most common cause of acute gastroenteritis worldwide. Accumulated virus decays over a period of days to weeks, possibly rendering contaminated oysters safe again. Sensitive molecular methods have been set up for shellfish analysis but without answering the question of infectious virus detection. Using the Tulane virus (TV), a norovirus surrogate that recognizes the same ligand as human norovirus in oyster tissues, the genome and infectious virus decay rates were estimated using inverse linear regression in a Bayesian framework for genome copies. Infectivity decreased faster than genome copies but infectious viruses were detected for... |

| Sea bass, Dicentrarchus labrax (mean weight: 748 +/- 13 g), were maintained before and during vitellogenesis in 1, 3, 8, 16 and 32 m(3) tanks, and then they were transferred to 2 m(3) tanks, for the spawning season. During the first 2 months of the experiment, the growth rates were significantly lower in smaller tanks (1 m(3)). In August, the oocyte diameters were significantly lower in smaller tanks (1, 3 and 8 m(3)) than in larger (16-32 m(3)) tanks. At the end of the experiment, the fish mean weight in the 1 m(3) tanks was significantly lower than in the 3 m(3) tanks, but oocyte diameters and plasma oestradiol concentrations were not significantly different between the volumes. This shows a longer acclimation requirement in smaller volume rearing.... |

| The fishing of pollack which concerns essentially, France, United Kingdom and Norway, and at a lower level Ireland and Denmark, is situated between 10 and 15000 tons a year. In 1996, France was the first producer of Pollack. Since 1980, a decrease of production is observed in Europe. In France, landing reached 3000t. in 1998 (Suquet, 2001). However, the demand remaining strong, aquaculture could be a solution to satisfy the deficit between the French production and the domestic demand. |
