116 sea turtles back in the ocean

Stranded between October 2023 and May 2024 on the French Atlantic and Channel coasts, 115 loggerhead turtles and one green turtle have returned to the ocean after their stay at the CESTM at the Aquarium La Rochelle.

Never before seen!

While 116 turtles have already returned to the ocean, more than 150 individuals, weighing a few hundred grams on average, have joined the care centre in recent months.

According to Florence Dell’Amico, head of the CESTM, ‘the numerous storms, strong and close together, have pushed the young individuals towards the European coasts. Stunned and paralysed by the cold, they have run aground in far greater numbers than in previous years. The unfailing mobilisation of the correspondents of the Eastern Atlantic Marine Turtle Network enabled rapid and effective care to be provided’.

A long-term research project

As well as caring for turtles in distress, the CESTM carries out numerous scientific studies, in partnership with national and international research laboratories.
Its vocation is to improve overall knowledge of these protected marine species, such as their geographical origin, their age, the pollution they ingest...

Oxygène (loggerhead sea turtle) and Oum (green sea turtle) are equipped with a satellite transmitter to track their movements.

Oxygène

The young Oxyègne turtle owes its name to internet users who were approached by the Aquarium. She is one of the oldest residents, having run aground on 25 May 2023 in Quinéville (50).
When she arrived at the Centre, she weighed just 3,796 g and measured just 30.5 cm.

Today Oxygène weighs 9456 g and measures 38.7 cm.

Oum

Oum ran aground in Seignosse (40) on 15 January 2023. Her name was chosen by schoolchildren at the Argonautica meetings, an educational project designed to raise awareness of the marine environment and climate using satellite data.
When she arrived at the Centre, Oum weighed 3766 g and measured 30.6 cm.

Today, the juvenile weighs 3830 g and measures 30.7 cm.

This programme makes it possible to track the movements of turtles in near-real time and to identify the factors that influence their journeys offshore (temperature, surface currents, etc.). This data helps to improve overall knowledge of the behaviour of these endangered species. It is also given to schoolchildren taking part in the Argonimals section of the Argonautica educational project developed by CNES.
