Preparation

On the bed of the river, make sure you establish a flat base in a flowing river.

Position

Position the Alevibox surrounded by stones.

Explanation

Do not hesitate to explain to the local residents

what you are doing.

Control of temperature

Spray water over the eggs to bring them to the river temperature.

Implementation

Place the eggs (here brown trout) with the help of a

funnel.

A dam could be useful downstream if the water level does not reach the Alevibox.

Opening of Avelibox

5 to 6 weeks after installing the Alevibox, it's time to open it. The youngsters will have developed in their place of birth and can re-colonize the creek.
