Bilan des perturbations phytoplanctoniques observées sur les côtes françaises en 1986 ArchiMer
Belin, Catherine; Berthome, Jean-paul.
In 1986, 23 discolored waters were observed ; dinoflagellates often were the cause of them. Many developments of Prorocentrum minimum occured ; two of them were associated with shel1fishes mortalities. At contrary, other species which are suspected to be toxic for shellfishes, as Gyrodinium aureolum and Gyrodinium spirale, have not been associated with mortalities, although they have been observed in several areas. The developments of Dinophysis (cf. acuminata or sacculus) caused provisional prohibitions of shellfishes selling, especially in the south of Brittany. Another specie was also implicated in toxicities : Prorocentrum lima. Human intoxications and economic consequences were rather important.

Bridging the gap between BSE risk assessment and consumer perception of the surveillance system in Japan OAK
KADOHIRA, Mutsuyo; HILL, Glen; SAWADA, Manabu; YOSHIDA, Seiko; 門平, 睦代; ヒル, グレン; 澤田, 学; 吉田, 省子.
Since the first case of bovine spongiform encephalopathy (BSE) was encountered in Japan in 2001, the country quickly responded with a change from passive to active surveillance. The response has not been a smooth one, though, and news media have contributed to opening the public’s eyes to inadequate behavior from government sources responsible for monitoring and protecting the health of consumers. The resultant information“gap” has served to augment the typical Japanese perceptions of risk assessment, as assessed in surveys from 2003 to 2005. Such false beliefs have caused consumers to call for 100% testing of animals for BSE despite accepted scientific standards which do not support such comprehensive and costly surveillance. Instead, testing agencies...

Changes in epidemiology of rotavirus in the Triângulo Mineiro region of Brazil: lack of two consecutive rotavirus seasons BJMBR
Dulgheroff,A.C.B.; Figueiredo,E.F.; Gouvêa,V.S.; Domingues,A.L.S..
Rotaviruses are the main cause of infantile acute diarrhea, and a monovalent (G1P[8]) vaccine against the virus was introduced into the Brazilian National Immunization Program for all infants in March 2006. The objectives of this study were to determine the rate and genotype distribution of rotavirus causing infantile diarrhea in the Triângulo Mineiro region of Brazil during 2011-2012 and to assess the impact of local vaccination. Fecal specimens were analyzed for detection and characterization of rotavirus using polyacrylamide gel electrophoresis, reverse transcription followed by polymerase chain reaction (PCR), and PCR-genotyping assays. Overall, rotavirus was diagnosed in 1.7% (6/348) of cases. Rotavirus positivity rates decreased 88% [95% confidence...

Coastal zones inventory by high resolution satellites ArchiMer
Loubersac, Lionel.
The development of tools for assessing impacts on coastal environments is a reality. These impact assessments need both baseline and monitoring studies. Satellite remote sensing data would be useful for coastal inventories (baselines) and monitoring if high spatial and temporal resolutions are yield compatible. An overview of the various sensors that could be used is presented. The constraints linked to the different resolutions are exposed. An example based on Spot simulated data and trends are developed.

Comprendre la structure et la dynamique du phytoplancton en réponse aux forçages naturels et anthropiques, et contribuer au développement des outils d’analyses automatisées. Vers un Système Intégré d’Observation. ArchiMer
Lefebvre, Alain.
Les écosystèmes marins sont soumis à des pressions d’origine anthropique très importantes depuis ces dernières décennies. Parmi ces pressions, les apports excessifs de nutriments vont impacter directement le phytoplancton et indirectement d’autres niveaux trophiques compromettant ainsi les biens et services écosystèmiques. On parle alors d’eutrophisation, phénomène répandu à l’échelle mondiale. La Manche orientale et la baie sud de la mer du Nord ne font pas exception. La partie française de cette zone est marquée par des proliférations massives de la Prymnésiophycée, Phaeocystis globosa, qui aboutiront au développement d’une mousse abondante et nauséabonde sur le littoral comme à des dysfonctionnements au sein des habitats benthique et pélagique. C’est...

Contamination de l'etang de Thau par Alexandrium tamarense. Episode de novembre a decembre 1998 ArchiMer
Abadie, Eric; Zouher, Amzil; Belin, Catherine; Comps, Marie-annick; Elziere-papayanni, Panayota; Lassus, Patrick; Le Bec, Claude; Marcaillou-le Baut, Claire; Nezan, Elizabeth; Poggi, Robert.
A bloom of the toxic dinoflagellate Alexandrium tamarense was observed for the first time in Thau iagoon between November and December 1998. Maximum cell concentrations detected in shellfish farming areas (85 000 Cells/1) were high enough to make mussels and clams unsuitable for human consumption (max. 850 ug. STX eq.100 g'1) while toxic levels in oysters did not exceed, or even reach, the international public health threshold established for PSP toxins. This event, new to French Mediterranean waters, was investigated by both local and national veterinary services and by the Ifremer teams involved in the National Monitoring Network for Phytoplankton and Phycotoxines (Réphy). The chronological and operational description of the event was compared with data...

Défis de la surveillance des maladies chez les coquillages marins en France ArchiMer
Lupo, Coralie; Francois, Cyrille; Arzul, Isabelle; Garcia, Celine; Joly, Jean-pierre; Renault, Tristan.
The basic concepts and objectives of animal disease surveillance are common to all types of animal production. Yet, the procedures for implementation have been mostly developed for terrestrial animal productions. Disease surveillance in marine shellfish calls for specific measures in view of the peculiarities of marine biology and rearing techniques. The main objective of disease surveillance in marine shellfish is to detect as early as possible exotic and newly emerging diseases. With this objective in mind, a national surveillance network for surveillance of mollusc diseases called Repamo has been developed. It combines passive reporting and risk-based surveillance.

Dépistage des sources de pollutions microbiologiques en Seudre amont et dans le bassin de Marennes Oléron ArchiMer
Auger, Christian; Courtois, Olivier; Kantin, Roger; Masson, Daniel; Piquet, Jean-come; Roesberg, Didier.
The oyster culture basin of Marennes - Oléron is characterized by the tastiness of its oysters and the good quality of its waters, and thus of its shellfish. On that account, the quasi-totality of the production areas are ranked A for non-burrowing shellfishes, thus confirming the privileged character of the basin. This microbiological and chemical quality contributing to the reputation of the basin's shellfish farms needs to be preserved. In this purpose, the Regional Shellfish Culture Section of Marennes - Oléron (SRC) approached the Ifremer in order to continue the monitoring of the microbiological quality carried out on different production areas susceptible to be affected by some bacteriological contaminations leading to a deterioration of the...

Effets climatiques sur les écosystèmes marins. Exemple du recrutement des Crustacés Cirripèdes sur la côte ouest du Cotentin ArchiMer
Dreves, Luc.
A nuclear power plant is set up at Flamanville (Channel; West coast of the Cotentin). For monitoring studies, one species (or a group of species) has been chosen in each major unit for a reference population dynamics study. Hard bottoms are covered by several species of barnacles. These species present different temperature affinities, and have reached here an equilibrium stage. The recruitment period of Balanus balanoides, the main species, has been determined. A relationship is established between the wintry temperature and the numerical importance of its spring recruitment.

Epidemiological surveillance, an essential tool for animal health and public health MV&Z
Côrtes, José de Angelis.
Characterized as a regular activity, the purpose of epidemiological surveillance is to obtain knowledge about health conditions and disease occurrence, providing support for control and / or erradication programs. Because of its comprehensive, dynamic and permanent nature, this activity has been qualified as a key function of national animal and human health systems. Epidemiological survey is its main tool and the means to obtain data includes passive and active surveillance, disease surveillance and monitoring, a more specific activity that has the objective of obtaining additional knowledge about aspects of an epidemiological pattern or performance of health-related operations.

Evaluation de la faisabilité et de la pertinence des protocoles « macrodéchets de fond » et « zooplancton gélatineux » testés sur les campagnes halieutiques côtières de l'Ifremer en 2017 ArchiMer
Lehmann, Léa.
The optimization of Ifremer's survey as a support of MSFD monitoring has been available since 2016 on the offshore fisheries surveys. Several protocols have been implemented, such as the “seafloor litter” and “gelatinous zooplankton” protocols. The aim of both protocols is to respectively collect data about the spatio-temporal evolution of waste and determine their origin, and to monitor the biodiversity of gelatinous zooplankton. From September to November 2017, they were tested on coastal surveys: NOURSOM, NOURNEINE, NOURMONT, ORHAGO, and NURSE. These surveys were primarily deployed to estimate the bentho-demersal species stocks as well as their spatio-temporal and trophic dynamics by a standardized sampling. Thus, this paper aims to assess the...
