Between May and October 2017, 30 fish from 58 km upstream the river mouth were marked: 5 A. fallax (using V9-2H acoustic pingers; 9x29 mm, introduced by the mouth, without anesthesia; 270 days of battery life), were released at the catching point; and 11 A. Anguilla, 13 M. cephalus, and 1 L. ramada (using V13 acoustic pingers; 13x36 mm, placed in the peritoneal cavity, with anesthesia and suture; 513 days of battery life), 52 km upstream (downstream Flix dam). An active tracking from a boat with a VR100 acoustic receiver and directional (VH110) hydrophone was also done. A. fallax went soon to the sea. M. cephalus were detected 3 months later their release, in July and August, upstream and downstream Xerta weir. None fish did not go in or out the coastal lagoons 10 months later. Obtained results seems indicate that the Ebre river possibly allows the recovery for those endangered species. To reinforce this information, other fish will be marked, including, if available, juveniles of A. sturio in 2019.
