Phenology and biological traits of migrating river lamprey sampled by electrofishing in the Oir river (France).

Description

 Monitoring of the migration of adult river lampreys has been carried out every year between February and May on the downstream part of the river Oir since 2009. Electric fishing is carried out every 3-4 weeks in a short sector downstream from a dam that is difficult to access.  The data consist of abundance indices and biological traits measured on the fish sampled :Sex, length and weight. 
The survey is carried out under the Research Observatory on Diadromes Fishes in Coastal Streamss (ERO DiaPFC) program. The data are stored in the database of the ERO. They are used to develop predictive models and tools for providing scientific advice to improve the management of this heritage species.
