Within the framework of the activities of the Aquarium La Rochelle, the Centre d'Etudes et de Soins pour les Tortues Marines (C.E.S.T.M.) welcomes every year marine turtles stranded or captured accidentally. After long months of care and convalescence, the animals use the return of fine weather to go back to the ocean.
Follow the course of a sea turtle, from observation to return to the ocean.
Discover the number of individuals who have been able to return to their natural environment in 32 years of C.E.S.T.M. activities.
Stranded between October 2023 and June 2024 on the French Atlantic and English Channel coasts, 136 loggerhead turtles and one green turtle returned to the ocean after their stay at the CESTM at the La Rochelle Aquarium.
More than 160 individuals, weighing a few hundred grams on average, have returned to the care centre in recent months.
Since 2008, the CESTM has been conducting a satellite monitoring programme for some of the marine turtles it rehabilitates.
It makes it possible to follow in quasi real time the turtles handed over to the Ocean. Thus, their positions recorded during their journey, combined with the data of various oceanographic parameters, make it possible to highlight the factors which influence their journey offshore (temperature, surface currents…).
Of the 8 marine turtles that returned to their natural environment in 2020, three have been equipped with a satellite transmitter and one of them is still working. It allows to follow the route of Kemen.
