The European eel, critically in danger species


Anguille européenne

Since June 15th 2006, every eel caught must be returned to the water regardless of its length. This arrangement is motivated by the food security following the analyzes carried out and revealing a too high rate of PCB's in the flesh of eels.


The minimum catching sizes

For other species fishing is authorized but…

…only during the opening periods, and the captured of these species is submitted to a regulation. Certain fish hand all the crawfish must be immediately returned to the water if their length is inferior to :


Taille légale du brochet Taille légale du sandre Taille légale du barbeau
for pike jack for pike perch for barbell
Taille légale de l'ombre Taille légale de la carpe Taille légale de la truite fario
for grayling for the carp, the tench, the chub, the orfe and the nase carp for the brown trout*, the rainbow trout, brook charr and the whitefish
Taille légale de la perche Taille légale du rotengle Taille légale du silure
for the perch
No sizes are applicable to the Brabant and Hainaut channels and the Nisramont lake
for the rudd 80 cm for the catfish


*ATTENTION, in the navigable watercourses and the channels, the length for the brown trout is elevated to 24 cm.


Code of Practice

Handle your captures with sensitivity and wet your hands first. If the fish has swallowed the bait too deeply, cut the line.

The length is measured:

For fish: from the mouth tip to the tailfin tip

Mesure de la taille d'un poisson


For crayfish: from the eye to the tip of the stretched tail.

Mesure de la taille d'une écrevisse


As such, during the fishery it is forbidden to keep fish or crayfish whose head or tail have been cut.


The maximum number of shots that can be stored


The fisherman must not keep in a fishing day more than a certain number of fish :

Pike (2)

Nombre maximum de brochets conservés par jour

Carp (2)

Nombre maximum de carpe conservé par jour

Grayling (4)

Nombre maximum d'ombres conservés par jour

Brown trout (5)

Nombre de truites conservées par jour

Gudgeon (30)

Nombre maximum de goujons conservés par jour

Minnow (50)

Nombre maximum de goujons conservés par jour


Code of Practice

If you don’t intend to catch your fish, no need to keep it in a basket, returned it into the water directly, it guaranteed a better survival of your catch.
