Abstract

Since 1984, monitoring has been carried out to observe migration phenology and quantify the abundance of migratory adults trout and sea trout  in Nivelle basin. A trapping system controls adults salmon migration by means of 2 traps, one in the downstream part and an other upstream to estimate the effectiveness. On this occasion, biometric characteristics are developed to characterize the population in order to feed this data set.

Project details

Project title: Observatoire de Recherche en Environnement des poissons diadromes sur les Fleuves Côtiers - Ecological Research Observatory on Diadromous Fish in coastal streams
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
Study area descriptions/descriptor: 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.

Methods

Method step description: Adult brown trout and sea trout have been monitored since 1984 by trapping at Uxondoa trap in the Lower Nivelle operating the whole year. Trap configuration allows only partial capture depending on the flow. A second upstream trap at olha in the upper Nivelle (since 1992) allows to estimate the effectiveness.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), sexed 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 description: Nivelle river, CdSandre=S52-0400 Latitude between 43.2426 and 43.3912; longitude between -1.4799 and -1.6694 Source latitude and longitude : 43.2173 -1.5231 Last confluence point latitude and longitude : 43.3854 -1.6639 The Nivelle is a 39 km long coastal stream of Pays Basque. It has its source in Spain and flows into the Bay of Biscay at Saint-Jean-de-Luz. Its drainage basin has a surface area of 238 km2, and is dominated by marly-calcareous formations. It is essentially agro-pastoral with more than 50% of the land area made of moors (Dumas, 2003). The oceanic climate, mild and wet (1700 mm year-1 in St-Pe´e-sur-Nivelle), provides a mean annual discharge of 5.4m3 s-1 downstream from the confluence of the main tributary, the Lurgorrieta, and 7 m3 s-1 at the mouth. The water, neutral to slightly alkaline, is of good quality upstream from Saint-Pée-sur-Nivelle, but deteriorates downstream.
Sampling description: The Uxondoa and Olha traps are in continuous operation from March to January, except during periods of high flooding. The traps are checked at least once a day.
