Abundances and biological traits of the juveniles trout sampled in the survey of trout abundance Indices (VIGITRUITE®) in the Bresle river (France)

Description :

 A survey started in 2018 is conducted every year in early autumn (early September) to quantify the abundance of juvenile trout in the Bresle. The electric fishing protocol VIGITUITE® is used. It targets trout young of the year (0+ parr), but older fish (juvenile  ≥1+) are also caught and included in this dataset.  The data consist of abundance indices and biological traits measured on the fish sampled: sex, length, weight and age. The latter is ascertained from scale samples taken from the fish which size does not allow to determine their age unambiguously.
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.

Funding : - INRAE : French National Institute for Agricultural, Food en Environment Research
- OFB : French Office for Biodiversity.
Since 2022, data collected on trout 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.
