About the Observatory

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

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

From a practical perspective, the ORE DiaPFC performs three complementary types of activities:

1) Long-term in situ monitoring: collecting long-term data series (observatory mission) to attempt to comprehensively understand population dynamics, and obtain operational outputs to manage, conserve and restore these populations or their habitats. For certain species (eel, salmon and trout), individual tagging and recapture programmes (PIT tag) have been in operation since 1993.

2) Experimental research: implementing more ad hoc research activities to address specific questions or methodological barriers. The experiments are conducted in the natural environment, at experimental facilities (artificial channels, lotic mesocosms, microcosms, etc.), or in silico via simulation.

3) Modelling:  continued development of demographic genetic simulation models.
