Experimental site in Argenton
Main activity
The Ifremer experimental site in Argenton, within LEMAR, is a tool dedicated to experimentation on marine bivalves under controlled conditions. It allows the study of the physiological response of these animals under the effect of biotic and abiotic factors of the environment, including different disturbances (e.g. pathogens, toxic algae, micro- and nano-plastics, pharmaceutical residues).
This experimental tool allows to work in a "controlled environment" in vitro/in vivo and thus to simplify the complexity of the natural environment ("free environment"). It is possible to control various factors, such as seawater temperature, pH, salinity, quality and quantity of the trophic resource, as well as the zoo-sanitary environment of the bivalves studied. Thanks to this tool, the teams can test hypotheses established in the natural environment and provide useful observations for in silico modelling.

The scientific purpose of the laboratory is based on understanding the mechanisms that regulate the functioning of marine ecosystems and their response to the multiple facets of global change (climate change, eutrophisation & invasive species).
The Argenton site is dedicated to experiments on marine bivalve molluscs under controlled conditions. It is distinguished by its exceptional water quality and the absence of shellfish farming sites or other human activities in the vicinity, thus avoiding any influence on the experiments. The research focuses on the effects of global change. The site hosts experiments carried out in collaboration with other university and CNRS researchers.
