Since 1982, migratory eels have been captured on the Bresle basin, first as a bycatch from salmonid trapping, then to observe migration phenology and quantify their abundance. 15 km from the river estuary a trapping system controls silver eels migration for a period of 6 months per year (3-6 months per year historically) and since 1994 an upstream trap captures yellow eel in their upstream migration 3 km from the estuary. On the occasion of the capture, biometric characteristics are taken to characterize the population in order to feed this data set.Sampling Description
Study Extent
Elvers are monitored by trapping on the facilities of Eu. As a consequence of its location, the trap does not cover the whole river and a bypass exists a few hundred meters downstream. The effectiveness of the trap is not monitored.Sampling
Since 1977, trapping of upstream-migrating elvers to the upstream parts of the Bresle River has been carried out by using an eel climbing ramp, which provides the eels with a substrate (brushes) that allows them to climb to the trap. Then they are counted and weighted alltogether, or measured in length individually.Method steps
- Elvers have been monitored since 1994 on the Bresle. The trap, which is located, at a distance of 3 km from the estuary, is checked twice a day throughout the elvers’ period of activity, ranging from march to November.
