WFD – Artois-Picardie Basin – Ecological status – Biological status – Fish
Description
The analysis focuses on monitoring fish populations in the only non-port transitional water body from the Belgian Border to the Bay of Somme and assessing their biological quality.
The ELFI fish indicator in French estuaries associated with this quality element is based on:
- total density of fish,
- density of diadromous fish,
- density of marine juveniles (in meso. and polyhaline areas),
- density of freshwater fish (in oligohaline areas),
- density of resident species,
- density of benthic fish,
- taxonomic wealth.
The water body monitored is sampled twice a year, three consecutive years for the calculation of the indicator. The most recent assessment is presented in the Artois-Picardie WFD Atlas. Previous statements are available in annual archives
