Descripción
Since 1982, migratory eels have been captured on the Bresle basin, first as a bycatch from salmonid trapping, then to observe migration phenology and quantify their abundance. 15 km from the river estuary a trapping system controls silver eels migration for a period of 6 months per year (3-6 months per year historically) and since 1994 an upstream trap captures yellow eel in their upstream migration 3 km from the estuary. On the occasion of the capture, biometric characteristics are taken 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.

Métodos de muestreo
Since 1977, trapping of upstream-migrating elvers to the upstream parts of the Bresle River has been carried out by using an eel climbing ramp, which provides the eels with a substrate (brushes) that allows them to climb to the trap. Then they are counted and weighted alltogether, or measured in length individually.
| Área de Estudio | Elvers are monitored by trapping on the facilities of Eu. As a consequence of its location, the trap does not cover the whole river and a bypass exists a few hundred meters downstream. The effectiveness of the trap is not monitored. |
|---|
Descripción de la metodología paso a paso:
- Elvers have been monitored since 1994 on the Bresle. The trap, which is located, at a distance of 3 km from the estuary, is checked twice a day throughout the elvers’ period of activity, ranging from march to November.
