About the Observatory

Environmental Research Observatory (ORE) on Diadromous Fish in Small Coastal Rivers (DiaPFC)

The ORE DiaPFC combines long-term in situ monitoring of amphihaline migratory fish populations and their environment, experimental facilities and in silico simulation tools.

From a practical perspective, the ORE DiaPFC’s activities are organised into three complementary strands:

1) Long-term in situ monitoring: through the collection of long-term data series (observatory mission) aimed at gaining a comprehensive understanding of population dynamics over time, and operational outputs for the management, conservation and restoration of these populations or their habitats. For certain species (eel, salmon and trout), individual tagging and recapture programmes (Pit Tag) have been in place since 1993.

2) Experimental research through the implementation of more ad hoc research initiatives to address specific questions or overcome methodological barriers. In this case, long-term monitoring is supplemented by experiments conducted either in the natural environment, in experimental facilities (artificial channels, lotic mesocosms, microcosms, etc.), or in silico via simulation.

3) Modelling, with the continued development of demogenetic simulation tools.
