Phenology and biological traits of migrating salmon (Salmo salar) sampled by trapping in the survey in the Oir river (France)

Latest version published by Institut national de recherche pour l’agriculture, l’alimentation et l’environnement (INRAE) on Dec 3, 2020 Institut national de recherche pour l’agriculture, l’alimentation et l’environnement (INRAE)

Since 1984, monitoring has been carried out to observe migration phenology and quantify the abundance of migratory salmon in the Oir basin. In the downstream part of the Oir River, a trapping system controls salmon migration by means of 2 traps, one for the descending fish and the other for the ascending fish. On this occasion, biometric characteristics are developed to characterize the population in order to feed this data set.

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.

Sampling Methods

The traps are surveyed in the morning every day and several times a day during periods of high migration throughout the year. Biometric measurement of the fish are recorded after their anesthesia with benzocaïne. The fish length is measured from the tip of the mouth to the fork of the caudal fin (1 millimeter precision). Fish are then weighed (0.2 g precision for smolts and 0.5 g for adults). Sex is determined on the basis of phenological criteria and maturity status is assessed by a gentle pressure on the belly that allows to get sperm in mature males. All the fish sampled are then released.

Study Extent Oir river : Latitude ranges from 48.6840 to 48.5985; longitude ranges from -1.2949 to -1. 0994. The Oir River is located on the southern edge of Normandy. It is a tributary of the Sélune, a coastal river that flows into the Bay of Mont Saint-Michel. The Oir is 21 km long and has a mean gradient of 1.1%. Annual mean discharge is 1.1 m3/s and the drainage basin area is 85.4 km2, which is dominated by sedimentary schist and metamorphic hornfels with granite inclusions. Agriculture is the main human activity and land use. Migratory fish cannot access the upper Sélune because a dam located 15 km from the sea blocks them. The Oir, with a 16 km long section accessible to Atlantic salmon, is the main spawning ground and the most productive tributary of the Sélune hydrographic network. The migratory fish monitoring station has been in operation since 1983 (GPS coordinates Lambert II extended: E 333834 - N 2409347). It is located on the entrance canal of the Cerisel mill and has two up and down trapping systems. It is located downstream of the Oir about 1.5 km from its confluence with the Sélune. Functional all year round, they allow to follow the migration of salmon.

Method step description:

  1. The migratory fish monitoring station has been in operation since 1983. Adults and smolts salmon are monitored by means of 2 traps, one for the descending fish and the other for the ascending fish. Salmon are monitored by trapping at the Cerisel Mill, both traps operating the whole year. Trap configuration allows only partial capture depending on the flow which requires to estimate the effectiveness of the traps.
