If you catch a tagged sole, please call ifremer at the following dedicated number 00 33 6 43 04 05 11 or send an e-mail to firstname.lastname@example.org.
If the tag is yellow, you can keep the sole, or release it if it looks well alive. If the tag is red, please keep it for us if you can, even if it is below the minimal landing size. In all cases, please make sure you record the date and location of the catch (lat, long), and if possible the total length of the fish.
You can also contact our colleagues from CEFAS and MMO in the UK, or ILVO in Belgium, who will transfer the info to us.
