Élevage de la palourde japonaise Ruditapes philippinarum dans le bassin d'Arcachon. Bilan des dix dernières années et perspectives de développement ArchiMer
Robert, Rene; Deltreil, Jean-pierre.
Farming of the Japanese clam Ruditapes philippinarum took place for the first time in 1980 in the Arcachon basin. After an experimentation period of about ten years, a farming strategy, taking into consideration the distinctive features found in the bay, was able to emerge. For example, in order to fight against clam predators, crabs such as Carcinus maenas, and balistes such as Balistes capriscus, vertical protection coupled with prior ground gravelling, and laying of nets over the beds during the summer months, have become necessary. The best raising technique seems to rest on early spring planting of middle size spats (T5), after checking that no brown rings are visible. If clam growth seems to be better in oceanic zones, it looks similar in other areas...

Essai de culture de l'huître plate Ostrea edulis dans le bassin d'Arcachon. Résultats préliminaires ArchiMer
Robert, Rene; Pichot, Yves; Comps, Michel.
From 1988 to 1989, a study has been conducted pertaining to the growth of the flat oyster Ostrea edulis, as well as Marteilia refringens and Bonamia ostreae outbreaks. Commercial mono specific farming (flat oysters), with low density or mixed (flat and hollow oysters) along with higher density, has been taking place in the Arcachon basin oceanographic sectors, where main hydrobiological parameters were acquired simultaneously. The excellent growth of the flat oyster was witnessed in mono specific farming. However this growth was average in mixed farming, probably due to higher total oyster density and interspecies competition. Regardless of the type of farming, Marteilia refringens infection was very quick and may have been related to climatic bay water...

Etude de la prolifération des algues vertes dans le bassin d'Arcachon ArchiMer
Manaud, Francois; Maurer, Daniele; Trut, Gilles; Auby, Isabelle.
Introduction Massive proliferations of algae and, in particular green macroalgae, have been known all over the continents for several decades. They affect various littoral sites and belong to diverse species (Ulva, Enteromorpha and especially Cladophora). In 1990, on the North Brittany shore, more than 80 000 m3 ulvas have been mechanically removed by affected communities. Up until recently, the Arcachon basin escaped from such phenomenon, even if the diversity and quantity of algae found there had already undergone increasing periods in the past. However, the first algae proliferations only started in the 80's, which scale was large enough to be a nuisance to all activities taking place in the basin. At first (starting in1982), those proliferations were...

La petite pêche en Aquitaine - le bassin d'Arcachon - Halieutique, socio-économie, usages et réglementations. 1999-2000 ArchiMer
Caill-milly, Nathalie; Leaute, Jean-pierre; Trouillet, Brice; Laborde, Jean-louis; Goumy, Cécilia; Prouzet, Patrick; Grandpierre, Alde; Lissardy, Muriel; Corlay, Jean-pierre.
Introduction : Intra-basin fishing is not grasped as well, partly because of a lack of distinction between pure professional fishing units and conchological units and on the other hand because of the large amount of ships. Poorly adapted codification of the equipment found in the basin is also contributing to this lack of information. Studies on the subject do exist, but the elements necessary to publish notices are not always gathered, this is leading to the proposal of a geographical systemic analysis on the basin. The steps that are being taken are complementing the development of the Geographical Information System already in place in the basin since 1993 through DEL at the Arcachon Ifremer as well as the PECOSUDE European study ¿ caractéristiques des...
