Article 11 Flapper

A flapper is a piece of netting with a mesh size at least equal to that of the codend, fastened inside a trawl, in such a way that it allows catches to pass from the front to the rear of the trawl but limits their possibility of return.

The flapper shall be attached at its front end and may be attached at its lateral edges inside the codend or in front of the codend.

The distance from the point of forward attachment of the flapper to the rear end of the codend shall be at least three times the length of the flapper.

In the Skagerrak and the Kattegat the length of the flapper shall not extend more than the length of 20 meshes into the codend.
