Description
Since 1994, monitoring has been carried out to observe migration phenology and quantify the abundance of migratory eels in the Scorff basin. In the downstream part of the Scorff River, a trapping system (2 traps) control silver eel migration. On this occasion, biometric characteristics are developed to characterize the population in order to feed this data set.
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 16,519 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Project Data
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.

Study Area Description | ERO DiaPFC is a Research Infrastructure based on three 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 |
Design Description | The issue of 'Research Observatory on Diadromes Fish in Coastal Rivers (ORE DiaPFC) is to study the evolution of diadromous fish populations as a result of environmental changes (climate change and changes related to agriculture ) that affect these rivers. |

- Principal Investigator
Sampling Methods
Silver eels have been monitored by trapping at the Tan Mill, downstream trap operating the whole year and Leslé Mill during less than 2 month. Traps configuration allows only partial capture depending on the flow.
Study Extent | Silver eels have been monitored since 1994.The two traps are surveyed in the morning every day throughout the year on the River Scorff in Brittany. |

Method step description:
- Silver eels have been monitored since 1994 by trapping at the Tan Mill, downstream trap operating the whole year. Trap configuration allows only partial capture depending on the flow. A second trap at Leslé Mill installed for smolt trapping (april- may) allows the accidental capture of a few eels.
