Description
Since 1982, migratory salmon have been captured on the Bresle basin to observe migration phenology and quantify their abundance. 15 km from the river estuary a trapping system controls salmon migration and since 1994 an upstream trap captures salmon 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
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 69,439 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.

| Funding | Funding - INRAE : French National Institute for Agricultural, Food en Environment Research - OFB : French Office for Biodiversity - Since 2017, data collected on salmon in the framework of the ORE DiaPFC have been included in the national program for the data collect in support of scientific advice for the Common Fisheries Policy for the European regulations on fisheries management. In this context, INRAE and OFB contribute to the National Work Program piloted by the DPMA of the Ministry of the Environment. This program is financially supported by FEAMP and FEAMPA. |
| 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. |

Sampling Methods
Trapping of smolts is conducted by means of filtering grids guiding the fish towards a waiting tank. Spawners are captured after swimming up a fish ramp where they trap themselves. For both stages, fish a measured and weighted individually, genetic and scale samples are taken on a subset of the captures, which are also tagged with individual PIT-tags.
| Study Extent | For both stages, trapping is not exhaustive and bypasses exists. Effectiveness of the trapping is thus monitored by procedure of mark-recapture. |

Method step description:
- Salmon smolts and spawners have been monitored respectively since 1982 and 1984 on the Bresle. The traps, which are located, at a distance of 3 km from the estuary (upstream - spawners) and 15 km (downstream – smolts), are checked and cleaned twice a day throughout the period of activity, ranging from December to may for smolts and march to December for spawners.
- Age is verified from scale reading according to standard methods described by (Baglinière and Le Louarn, 1987) and (Richard and Bagliniere, 1990).
