說明
Since 1993, an annual campaign is conducted to quantify the abundance of juvenile Atlantic salmon in the Oir basin. It is usually done in September and according to the protocol of Prévost and Baglinière (1995). The electric fishing protocol of Prévost and Baglinière (1995) is used, which is specific to Atlantic salmon young of the year (0+ parr) . Sampling is restrited to areas with shallow running water flowing on coarse bottom substrate i.e. the preferred habitat of young of the year salmon.This data set consists of the abundance and biological traits measured on the fish sampled on this occasion. Observations made on this occasion are descriptive data (species, sex, maturation and biometric (length, weight). In addition, scales samples are taken to determine the age of the fish.

計畫資料
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.

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. |

Sampling is conducted at 11 sites spread over the mainstem and over the 2 main tributaries in the area of the Oir hydrographic network colonized by Atlantic salmon. Since 2016, 1 site is sampled over the network colonized by Atlantic salmon to vérify this limit. The sites are the same every year and are visited once a year in the beginning of autumn (September).
| 研究範圍 | Oir river, CdSandre=I9280600 Latitude between 48.6840 and 48.5985; longitude between -1.2949 and -1. 0994 Source latitude and longitude : 48.6667 -1.1138 Last confluence point latitude and longitude : 48.6305 -1.2943 Oir river is located in the south of the Manche department, the Oir is a tributary of the Sélune, small Normandy coastal river flowing into the Bay of Mont Saint-Michel. The course of the Oir, long 21 km, east west, has an average gradient of 11 ‰. Its watershed of 87 km², dominated by sedimentary schist land and corneal including some granitic enclaves. The water is near neutral and reasonable quality but with high nitrate levels. On this basin, human activities are mainly from agriculture (meadows, fodder crops, dairy cattle). The upstream Sélune is not accessible to migratory fish. They are blocked to fifteen kilometers from the sea by a dam. Oir river, with its 12 Km accessible to migratory fish spawning tributary is the most productive of the network |

方法步驟描述:
- Juvenile salmon are caught by electrofishing. Until 2021, a 400 Hz pulsed current generator and then a direct current generator were used and the following procedure is followed: 1 Two large dip-nets with metal frames are placed facing the current, lying on the bottom, and kept at a fixed position. 2 The anode scans an area of about 4-5 m upstream of the dipnet in the vein of water filtered by them. 3 Fish attracted by the anode and shocked go down into the nets guided by the electrode and driven by the water flow. 4 If necessary, the fish stuck on the bottom or in aquatic vegetation are recovered by a small hand net. 5 - Individuals are transferred into a bucket previously filled with water. The whole team moves laterally several meters (the carrier of the martin fisherman taking care not to step on the area he will next explore with the anode) out of the area that has just been disturbed by the electric field, then steps 1-5 are repeated. When one bank is reached, the progression is a few meters upstream. 5 The sampling at a given site stops after 5 minutes of actual fishing time - ie during which the electric field is applied in the water - measured directly on the counter of the electric fishing equipment. Juvenile abundance is quantified by the number of 0+ captured for a unit effort (5 minutes of fishing under the conditions specified above).
- Age is verified from scale reading according to standard methods described by Baglinière & al (2022).
