Under the terms of paragraph 7 of Order 1/DG/2025, the sentinel fishery for undulate ray will be closed as of December 9 for vessels licensed in the Central, Southwest, and Algarve zones. From that date onwards, each licensed vessel may only land one specimen of this species per tide.

Masters of the vessels must continue to fill in the registration documents with the total catches made, and all specimens—except one—must be returned to the sea.
