Descripción
Since 1984, monitoring has been carried out to observe migration phenology and quantify the abundance of migratory adults shad in Nivelle basin. In the Nivelle River, a trapping system controls adults shad 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.

Datos del proyecto
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.

Métodos de muestreo
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.
| Área de Estudio | 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 5.4 m3 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. |

Descripción de la metodología paso a paso:
- Adult shad 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.
