SHORT-TERM VARIATION OF BACTERIAL COMMUNITIES CONCENTRATION AND ACTIVITY IN AQUACULTURE ECOSYSTEMS. Two kinds of short-term experiments were carried out on sea-water bacterial communities of shrimp aquaculture in Polynesia at the Centre Océanologique du Pacifique (Tahiti). A 12 m3 sea-water tank was considered. The total number (AOC) and hétérotrophie activity of bacteria were studied during a 48 hours experiment with a 2 hours sampling time The total bacterial community was about 10? bacteria, and nitrifying bacteria were about 10 bacteria ml-1 and could showed doubling time of 7 hours. Several nitrogen sources were added in five liter flasks. With N-NH4 enrichment no great changes in activity and number could be seen. With organic nitrogen the number of... |

Il ne prétend pas rendre compte de l'ensemble des données collectées depuis cette précédente édition. Cependant, il a pour ambition de présenter de manière synthétique, l'activité et la situation économique de la flotte de pêche française métropolitaine (façades mer du Nord Manche, Atlantique et Méditerranée), à destination d'un public très large. La Synthèse des flottilles de pêche 2007 est une compilation de fiches synthétiques, chacune d'entre elles étant construite sur le même format. : - La fiche de synthèse France Métropolitaine Elle décrit la flotte des façades Mer du Nord Manche, Atlantique et Méditerranée.

After a reminder on the program SYSCOLAG (Coastal and Lagoons Systems), of the regulatory and legislative context in territorial economic planning on the coast, we describe the structure of the developed methodological tool. We clarify then the method according to its three main trunk roads: effects of the activities and uses on the economy of the territory, the effects of the activities and uses on the natural environment and the living environment, the evaluation of the interactions between activities and uses. We apply the method exposed in a frame demonstrator by taking the scenario of the lagoon and coastal territory of the Thau Basin (Hérault). A set of appendices, including in particular evaluation grids are supplied with support for the... |
