Brent Eel Recovery Project

I joined Chris Cockel, Nature Conservation Officer with the Environment Trust, to check the elver trap at Brentford Lock yesterday. You can read the background to this excellent project here http://etrutvolunteering.blogspot.co.uk/p/river-brent-eel.html.

A constant flow of water through the plastic bristle brushes built in the floor of the fish pass enables the young eels to migrate past barriers such as this weir.

The trap is checked every day. Here's Chris emptying the chamber before inspecting today's catch.

The elvers are counted and a representative sample are measured. 114 recorded in the trap today. On a good day it can be over 1000.

After the vital statistics are collected, the young eels are safely released into the river to continue their upstream migration.

Congratulations to the Environment Trust and all the volunteers working to protect and improve our eel stocks.
