Descripción
Since 1984, monitoring has been carried out to observe migration phenology and quantify the abundance of migratory eels in the Oir basin. In the downstream part of the Oir River, a trapping system controls eel migration (a descent trap since 1984 for silver eels that descend and more recently, in 2017 an upstream trap for yellow eels). On this occasion, biometric characteristics are developed to characterize the population in order to feed this data set....

Datos del proyecto
The Research Observatory on Diadromous Fish in Coastal Streams (ORE DiaPFC) is a research infrastructure steered by INRAE in partnership with OFB and part of the OFB-INRAE R&D center. It’s focused on the study of the evolution of diadromous fish populations under the influence human induced environmental changes that affect these rivers (mainly climate and effects of agriculture). Diadromous species of primary interest are salmon (Salmo salar), trout (Salmo trutta), eel (Anguilla Anguilla), shads (Alosa sp.), and lampreys (Lampetra sp. and Petromyzon marinus). These species are threatened by the consequences of human activities. They are flagship species for the biodiversity of coastal streams. Nowadays, these streams are the main refuges for diadromous fish that have disappeared or dramatically declined on larger rivers. This ERO DiaPFC is a Research Infrastructure based on four coastal streams of the Atlantic and Channel coast of France: the Bresle and the Oir in Normandy, the Scorff in Brittany and the Nivelle in the Pays Basque. These four rivers are equipped with diadromous fish trapping facilities and are thoroughly and continuously surveyed from the mid 1980s. They are twinned with experimental ecology facilities located in Rennes (Brittany) and Saint-Pée-sur-Nivelle (Pays Basque). This set of facilities is complemented by individual-based eco-genetic simulators for in silico experimentation on virtual populations.

Descripción de la metodología paso a paso:
- Since 2017, trapping of upstream-migrating elvers to the upstream parts of the Oir River has been carried out by using an eel climbing ramp, which provides the eels with a substrate (brushes) that allows them to climb a 40% slope.
- Silver eels have been monitored since 1983 by trapping at the Cerisel Mill, downstream trap operating the whole year. Trap configuration allows only partial capture depending on the flow which requires to estimate the effectiveness of the traps.
