Lucas, Ronan / Courties, C. / Herbland, Alain / Goulletquer, Philippe / Marteau, Anne-laure / Lemonnier, Hugues - 2010In tropical shrimp ponds, the increasing of feed input, concomitantly with the stocking shrimp biomass, induces an eutrophication of the ecosystem. Although difficult to maintain, its stability is required to guarantee the success of the culture. A 110-day period of phytoplankton and...Contributeur (s):

Lemonnier, Hugues / Courties, Claude / Mugnier, Chantal / Torreton, Jean-pascal / Herbland, Alain - 2010A field survey was conducted on two intensive shrimp farms using similar technical practices: one (DF) historically affected by a vibriosis, the other (HC) in which the pathogen has been observed although no mortality event has occurred. Because historical data suggest that eutrophication process...Contributeur (s):

Shrimp farming in New Caledonia typically uses a flow-through system with water exchange rates as a tool to maintain optimum hydrological and biological parameters for the crop. Moreover, the effluent shows hydrobiological characteristics (minerals, phytoplankton biomass and organic matter)...Contributeur (s):

Debenay, J.p. / Della Patrona, Luc / Herbland, Alain / Goguenheim, H - 2009This study was carried out in shrimp ponds from New Caledonia, in order to determine the cause of the exceptional proportion of abnormal tests (FAI) (often >50%, sometimes >80%). FAI was positively correlated to the quantity of easily oxidized material (EOM) deposited on the bottom of the...Contributeur (s):

Debenay, Jean-pierre / Della Patrona, Luc / Herbland, Alain / Goguenheim, Hemitti / Peignon, Jean-marie - 2009Meiofauna is a functional group made of small benthic metazoans 45 to 500µm in size. Although protista, foraminifera living in this kind of environment are often put in to the meiofauna. Meiofauna has been studied in New Caledonia for its double role as biological indicator for monitoring pond...Contributeur (s):

Guillaud, Jean-francois / Aminot, Alain / Delmas, Daniel / Gohin, Francis / Lunven, Michel / Labry, Claire / Herbland, Alain - 2008Seasonal variations in nutrient inputs are described for the main rivers (Loire and Vilaine) flowing into the northern Bay of Biscay. The river plumes are high in N/P ratio in late winter and spring, but not in the inner plume during the summer. Conservative behavior results in most nutrients...Contributeur (s):

Della Patrona, Luc / Brun, Pierre / Herbland, Alain - 2007Shrimp culture in New Caledonia has developed according to the "intensified" semi-intensive model which uses ponds that stretch over several hectares. Local shrimp farms are for the most part installed in "tannes", barren, highly saline areas of the back mangrove forest. These...Contributeur (s):

Lemonnier, Hugues / Herbland, Alain / Salery, Lucas / Soulard, Benoit - 2006The "Summer Syndrome", a septicemic vibriosis caused by Vibrio nigripulchritudo, is responsible for one of the two main seasonal mortalities which affect shrimp aquaculture in New Caledonia. It was identified for the first time in December 1997 in an intensive shrimp farm (called farm DF...Contributeur (s):

Petitgas, Pierre / Masse, Jacques / Bourriau, Paul / Beillois, Pierre / Bergeron, Jean-pierre / Delmas, Daniel / Herbland, Alain / Koueta, Noussithe / Froidefond, Jean-marie / Santos, Maria - 2006The spatial pattern in hydro-plankton and fish distributions and their relationship were analysed based on the spring 2000 fisheries acoustic survey. The importance of this survey was that it was a multi-disciplinary platform which collected an extensive set of parameters in the hydro-plankton...Contributeur (s):

Lemonnier, Hugues / Thomas, Yoann / Legrand, Alexandre / Martin, Jean-louis / Herbland, Alain - 2006In the booming context of shrimp culture in French Caledonia, some research actions need to be considered in order (i) to make sure this production will not impact the quality and biodiversity of the coastal environment it is contingent upon (ii) for the field to highlight, based on objective bases...Contributeur (s):

Labry, Claire / Delmas, Daniel / Herbland, Alain - 2005Previous studies conducted on the continental shelf in the Southeast Bay of Biscay influenced by Gironde waters (one of the two largest rivers on the French Atlantic coast) showed the occurrence of late winter phytoplankton blooms and phosphorus limitation of algal growth thereafter. In this...Contributeur (s):
