    Description / Table of Contents: Le Rephy et le Rephytox sont des réseaux de surveillance du littoral créés par l'Ifremer en 1984. Ils ont pour objectifs d'observer le phytoplancton et les paramètres hydrologiques associés (Rephy), ainsi que de détecter les toxines algales s'accumulant dans les coquillages (Rephytox). Cet ouvrage a pour triple ambition de : décrire le Rephy-Rephytox, fournir une vision globale des données acquises par ces réseaux pendant les trois dernières décennies, montrer l'importance des séries de données environnementales acquises sur le long terme. Le Rephy et le Rephytox sont désormais reconnus aux niveaux national et international. Chacun des réseaux est décrit en détail dans son format actuel, incluant les objectifs, les stratégies d'échantillonnage, les lieux de prélèvement, les paramètres mesurés ainsi que les méthodes. Les données sur le phytoplancton acquises par le Rephy permettent de dessiner le paysage des populations microalgales du littoral,dans l'espace et le temps, à différentes échelles. Une typologie des espèces emblématiques est ainsi proposée. L'utilisation des données dans le contexte de la directive-cadre européenne sur l'eau fournit une carte de la qualité des eaux littorales. Le traitement des séries de données phytoplancton ethydrologie par modèle linéaire dynamique (DynamicLinear Model, DLM) donne un éclairage tout à fait inédit et novateur. Un panorama détaillé sur les occurrences saisonnières des trois familles de phycotoxines présentes sur le littoral est également exposé. Cet ouvrage s'adresse en particulier aux scientifiques travaillant sur les écosystèmes littoraux, mais aussi à tout public intéressé par ces problématiques.

    Diversity and regional distribution of harmful algal events along the Atlantic margin of Europe (2021)

    Description: The IOC-ICES-PICES Harmful Algal Event Database (HAEDAT) was used to describe the diversity and spatiotemporal distribution of harmful algal events along the Atlantic margin of Europe from 1987 - 2018. The majority of events recorded are caused by Diarrhetic Shellfish Toxins (DSTs). These events are recorded annually over a wide geographic area from southern Spain to northern Scotland and Iceland, and are responsible for annual closures of many shellfish harvesting areas. The dominant causative dinoflagellates, members of the morphospecies ‘Dinophysis acuminata complex’ and D. acuta, are common in the waters of the majority of countries affected. There are regional differences in the causative species associated with PST events; the coasts of Spain and Portugal with the dinoflagellates Alexandrium minutum and Gymnodinium catenatum, north west France/south west England/south Ireland with A. minutum, and Scotland/Faroe Islands/Iceland with A. catenella. This can influence the duration and spatial scale of PST events as well as the toxicity of shellfish. The diatom Pseudo-nitzschia australis is the most widespread Domoic Acid (DA) producer, with records coming from Spain, Portugal, France, Ireland and the UK. Amnesic Shellfish Toxins (ASTs) have caused prolonged closures for the scallop fishing industry due to the slow depuration rate of DA. Amendments to EU shellfish hygiene regulations introduced between 2002 and 2005 facilitated end-product testing and sale of adductor muscle. This reduced the impact of ASTs on the scallop fishing industry and thus the number of recorded HAEDAT events. Azaspiracids (AZAs) are the most recent toxin group responsible for events to be characterised in the ICES area. Events associated with AZAs have a discrete distribution with the majority recorded along the west coast of Ireland. Ciguatera Poisoning (CP) has been an emerging issue in the Canary Islands and Madeira since 2004. The majority of aquaculture and wild fish mortality events are associated with blooms of the dinoflagellate Karenia mikimotoi and raphidophyte Heterosigma akashiwo. Such fish killing events occur infrequently yet can cause significant mortalities. Interannual variability was observed in the annual number of HAEDAT areas with events associated with individual shellfish toxin groups. HABs represent a continued risk for the aquaculture industry along the Atlantic margin of Europe and along the Atlantic margin of Europe and should be accounted for when considering expansion of the industry or operational shifts to offshore areas.
