Caractéristiques de dragues et pêcheries
Provedor de dados: 5
Autores: Pitel, Mathilde; Berthou, Patrick; Fifas, Spyros.
Basically, a dredge is a bottom-towed gear and consists of a metal frame with a blade or teeth, to dig into the sediment and extract the shelled molluscs, and a mesh bag to collect the catch. Whereas hand dredging is observed on some intertidal beds (Donax trunculus in France), the use of dredge generally needs a fishing boat. There is a great diversity of dredge types, with specific designs used to target different species in particular beds:   Manual dredges for Donax (Donax trunculus), Warty venus (Venus verrucosa) and clams (Venerupis pulastra, Ruditapes sp)   Dredges for King scallops (Pecten maximus)   Dredges for Warty venus (Venus verrucosa)   Dredge for Queen scallops (black and white, Chlamys varia and Chlamys opercularia)   Dredges for small...

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...

Contamination chimique du milieu marin : de la mesure à l'évaluation des risques
Provedor de dados: 5
Autores: Abarnou, Alain.
This activity report entitled (“Chemical contamination of the marine environment: from measurement to risk assessment”) summarizes the main stages my career at Ifremer from November 1975 to june 2013. The first chapter deals with the seawater chlorination and chlorinated waters released into the sea, the identification and the conditions of the formation of various by-product of these processes. The second chapter concerns PCBs, their nature, their chemical analysis in environmental matrices. PCBs are considered as the best examples of persistant and bioaccumulable compounds and therefore, in all this report they are flagship contaminants to which other groups of studied substances are compared. The third chapter refers to studies performed within marine...
