Dados Sobre o Projeto

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.

Métodos de Amostragem

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.

Descrição dos passos do método:

1. trout 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.
2. Age is verified from scale reading according to standard methods described by Baglinière & al (2020) Bagliniere, J.-L., Hamelet, V., Guéraud, F., Aymes, J.-C., Goulon, C., Richard, A., Josset, Q., Marchand, F., 2020.
