RSPCA study shows rehabiliated seals return to the wild successfully
Rehabilitated seals return to the wild without any adverse effects and can swim and dive just as well as normal healthy wild seals, latest RSPCA research shows.
Although those involved in nursing sick and injured seals back to full health at the wildlife centre were always convinced this was the right course of action, there were some sceptics who questioned whether a rehabilitated seal would survive as well as a wild seal.
The research was carried out in collaboration by staff at our East Winch Wildlife Centre and scientists from the Sea Mammal Research Unit, University of St Andrews, Scotland.
Alison Charles, manager at centre, said: "We have always done everything possible to return sick and injured seals back into the wild, and give them the best chance of survival once released, but until now we have never had the scientific evidence to back this work up. We felt it was really important to show people that these seals deserve a second chance and that rehabilitation does work. Through this study we can clearly see that our rehabilitated seals could dive just as well as wild seals and this was a clear indicator of their health and strength when back in the open waters."
Satellite transmitters were glued to the fur on the back of six rehabilitated harbour seals. The transmitters collected and relayed detailed information about the seals every day for six months or so after their release. For the first time experts could remotely monitor the seals' health and not just the fact that they were alive. Much the same as NHS patients being sent home with heart monitors.
On release all rehabilitated animals immediately demonstrated diving capabilities that persisted during their tracking periods. And they were similar to capabilities in apparently healthy adults. The findings also found the seals did travel significant distances once they were released.
