11/01/2018 - Movements of sturgeons marked with transmitters

Within the scope of the monitoring activities of the project (Action D2 “Checking the effectiveness of repopulation activities involving Acipenser naccarii* and other species”), which aims to verify directly the effectiveness of repopulation activities involving the Adriatic Sturgeon* and the 4 species of freshwater cyprinids released after specific spawning and breeding activities, the data downloaded from the buoys is providing interesting information on the movements of released sturgeons fitted with a sonar emitter. 

The sturgeons move at a remarkable speed! Here are some examples of their movements: the sturgeon fitted with transmitter no. 11645 (let us call it sturgeon 11645) had been reported in the area of Santa Maria Maddalena (Rovigo) on 14 August 2017 at 04:36; the next day (15 August), the same sturgeon passed through the area of Papozze at 03:25 - in less than 24 hours, it travelled approximately 40 km! Sturgeon 11607 was released in Piacenza on 16 May 2017, and travelled past Bereguardo on 7 September 2017.


As well as confirming the effectiveness of the monitoring network and repopulation activities, the data being collected provides very important insights into the study of the species.

Our work continues!
