Aquaculture of Microalgae in New-Caledonia (AMICAL): development of a co2 supply device for intensive microalgae culture. assessment of the device with carbon budget of cultures in microcosm. ArchiMer
Nakagawa, Kento; Coulombier, Noemie; Le Dean, Loic; Brun, Pierre; Chim, Liet.
Aquaculture diversification has been set as a major policy by New Caledonia public authorities. This has been set up to carry by ADECAL Technopole which carries projects in view of developing cultivation marine species native from Caledonian waters. In this context, the development of micro-algal cultures has been identified as a priority. The study presented has been co-funded by Glencore company in New Caledonia and achieved under the program entitled Aquaculture of MIcro-algae in new-CALedonia (AMICAL) and has two objectives: (i) designing a device to bring dissolved CO2 into micro-algae cultures with a minimum release in atmosphere of this green-house gas and (ii) to assess this device by carrying out carbon budget of micro-algae cultures in...

Dinoflagelles toxiques sur les cotes francaises pendant l'ete 1983.Validite du test-souris pour le controle routinier de secteurs mytilicoles contamines par la toxine du Dinophysis. ArchiMer
Marcaillou-le Baut, Claire; Le Dean, Loic; Truquet, Philippe.
Following exceptional outbreak of toxic dinoflagellate species in Vilaine Bay (summer 1983) a survey was carried out: variations in phytoplankton abundance and distribution in water and in mussel guts were followed. In the same time toxicity studies using mouse-test were performed with contaminated shellfishes, and mouse-test calibration was attempted. In spite of sampling and analysis conditions could be open to criticism, results obviously showed relation between shellfishes toxicity and occurrence of responsible species: Dinophysis acuminata.

Hydrologie et distribution de dinophysis en juin 1988, dans la frange côtière nord-Gascogne ArchiMer
Lassus, Patrick; Truquet, Philippe; Le Dean, Loic; Bardouil, Michele.
During the oceanographic cruise of June 1988, phytoplankton and correlated hydrological parameters were studied in the coastal area between Camaret and Ile d'Oléron. 62 stations were sampled in the 0-30 m layer within the 50 m depth limited coastal area. Observations focused on two toxic dinoflagellate species: Dinophysis spp and Gyrodinium aureolum. Dinophysis spp is more abundant in the Loire/Vilaine area, which is.characterized by high surface Nitrate levels, high 30 m depth Phosphate levels and Chlorophyll a amounts higher than elsewhere during the survey. This particuliar pattern can be related to the Nutrient outputs of Loire and Vilaine Rivers. Max. Dinophysis concentrations were observed in Vilaine bay (very high Phosphate levels) and in Douarnenez...

Etudes préliminaires sur la sensibilité d'organismes planctoniques marins vis à vis de deux insecticides et d'un herbicide ArchiMer
Marcaillou Le Baut, C; Bardouil, Michele; Bocquene, Gilles; Le Dean, Loic; Truquet, Philippe.
This work is the preliminary synthesis of some toxicological tests conducted on three pesticides. This recapitulation would not have been possible without the contribution of our trainees, Misses V. Perles and H. Le Boulicot and MM. M. Falchier and G. Gaty who contributed largely to this study, supervised by the laboratory staff. The obtained results cannot be considered as definitive. The urge to answer the needs did not leave us enough time to fine tune and/or complete the results; for example we still have not determined the lethal dose for 50% of the individuals. [...]
