Provedor de dados: 5
Autores: Masson, Daniel; Courtois, Olivier; Masson, Nadine; Guesdon, Stephane; Rocher, Gregory; Margat, Sylvie.
The carrier ship's deballasting activity in french ports and coastal areas can introduce unwanted or noxious species,with detrimental economical and sociological consequences upon shore based activities ; These activities represent one of the most preeminent sources for employment and incomes along the french coasts ,via coastal fishing,aquaculture,tourism. A ship's ballast water study in sorne french ports has been carried out ,to seek for presence of harmfull or pathogenic organisms.Results let appear pathogenic bacteriae in half of the ships,and weIl known toxic phytoplancton species (from Spain ,north Africa) The technical problem of ballast water treatment is considered.

Autores: Verlaque, Marc; Belsher, Thomas; Deslous-paoli, Jean-marc.
A detailed study of vegetative and reproductive phases of several populations of a common species of Ulva from Thau Lagoon (France, Mediterranean Sea) showed that the material is in good agreement with Asiatic Ulva pertusa Kjellman. Since October 1994, the date of its first observation in Thau Lagoon, U. pertusa has developed abundant reproductive populations. It is highly probable that this species was introduced at Thau along with oyster transfers from the Pacific. Ulva pertusa is new to the Mediterranean Sea.

Evaluation du risque d'introduction d'espèces indésirables par l'intermédiaire des eaux de ballast des navires
Provedor de dados: 5
Autores: Fouche, Dominique; Masson, Daniel.
The discharge of ship's ballast waters in coastal areas is considered as a vector for exotic species introduction, a threat for the local ecosystems or even the mariculture activities. The most worrying are the toxic phytoplanktonc. Unwanted effect presently documented in the world were rewieved. The risk analysis applied to this problem is discussed. Regulations and research programs about ballast waters in several countries were also overviewed. A ship's arrivai study in Charente-Maritime (France) let appear a large percentage of them were coming from areas where the occurrence of toxic phytoplankton blooms are common. Known technical solutions, populations and guidelines are recorded. A non exhaustive list of toxic phytoplankton blooms occurences in...
