Phenology and biological traits of migrating trout and sea trout (Salmo trutta) sampled by trapping in the survey in the Bresle river (France)

Description :

 Since 1982, migratory trouts 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 trout migration and since 1994 an upstream trap captures trouts 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

Title : ORE-DiaPFC Observatoire de Recherche en Environnement des poissons diadromes sur les Petits Fleuves Côtiers  - ERO DiaPFC Ecological  Research Observatory on Diadromous Fish in coastal streams
Abstract : 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-L'Institut Agro-UPPA 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 : - INRAE : French National Institute for Agricultural, Food en Environment Research 
- OFB : French Office for Biodiversity. 
- Since 202, data collected on troutin 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
