Ce rapport a été réalisé à la demande de la Direction Départementale de la Protection des Populations de l’Hérault (DDPP34). Les résultats en toxines lipophiles réglementées (Acide Okadaïque, Dinophysis toxines et Pectenotoxines uniquement) dans les moules et les huîtres prélevées au point « Parc Leucate 2 » dans le cadre du REPHYTOX, ainsi que les dénombrements du phytoplancton toxique du genre Dinophysis réalisés dans le cadre du REPHY dans la lagune de Leucate, sont présentés sur des graphiques permettant une visualisation temporelle des épisodes de contamination entre janvier 2014 et décembre 2020. |

An investigation into the distribution of Dinophysis spp. in coastal waters off the south coast of Ireland was carried out in July 2007. Dinophysis acuta was present as a sub surface layer containing up to 55,000 cells L-1. The population had a high percentage of viable cells (mean: 89%; median: 94%; n = 24) with a high specific division rate (~0.55 d-1). The layer, of approximately 5 m thickness, did not coincide with the fluorescence maximum and was present as a patch of horizontal dimension less than 10 km x 7 km. Both conventional and towed undulating CTD used in conjunction with high vertical resolution sampling methods showed the patch of Dinophysis to move with a similar speed and direction as the coastal flow, which ran parallel to the coast in the... |

Dinoflagellate species of Dinophysis are obligate mixotrophs that require light, nutrients, and prey for sustained growth. Information about their nitrogenous nutrient preferences and their uptake kinetics are scarce. This study aimed to determine the preferred nitrogen sources in cultures of D. acuminata and D. acuta strains from the Galician Rías Baixas (NW Spain) and to compare their uptake kinetics. Well-fed versus starved cultures of D. acuminata and D. acuta were supplied with N15 labeled inorganic (nitrate, ammonium) and organic (urea) nutrients. Both species showed a preference for ammonium and urea whereas uptake of nitrate was negligible. Uptake rates by well-fed cells of D. acuminata and D. acuta were 200% and 50% higher, respectively, than by... |
