The main purpose of this study is to know how a rehabilitated harbour seal (Phoca vitulina) reintegrates his natural habitat.
CHENE is a rehabilitated center for all wildlife. Each year, we take care of harbors, useally young ones, coming from beach in the north of France (from Baie du Mont-Saint-Michel to Dunkerque). Generally these youngs arrive because of the separation from the mother just before weaning or because they cannot find sufficient food for their energy requierements just after it weaning. Others arrive because of injuries or deseases.
It is important to know what happene for these animals after release.
This study provides us information about their movement patterns and their behaviour. The tag gives us different kind of data : dive depths, dive durations and haultout.

L'objectif principal de cette étude est de connaître le devenir des phoques veaux-marins (Phoca vitulina) soignés, une fois de retour dans leur mileu naturel.
Le CHENE est un centre de sauvagarde de la faune sauvage. Chaque année nous accueillons des phoques, souvent des jeunes, provenant des plages de la côte nord de la France (de la Baie du Mont-Saint-Michel à Dunkerque).La pluspart du temps, les jeunes que nous accueillons arrivent au centre à cause d'une séparation prématurée d'avec la mère, avant le sevrage, ou à cause de difficultés à s'alimenter juste après le sevrage. Certains arrivent également suite à des contusions ou des maladies.

Il est important pour nous de savoir ce que deviennent ces animaux après leur lâcher. Cette étude nous apporte des informations sur leurs déplacements et aussi sur leur comportement. Les balises enregistrent différentes informations : profondeur et durée des plongées et le temps passé au sec.
