At Polaria the seals are trained at the same time as they are fed. They are not trained to perform or make any kind of "seal show", but to stimulate them mentally. Animals in captivity that are trained live a much better life than those that are untrained.
Mainly the seals are trained to co-operate with veterinary examinations, for example to come out of the water and to open their mouths. These exercises make it possible for our keepers and veterinary staff to examine the seals daily and to satisfy ourselves that they are healthy and in generally good shape.
The seal training is based on the same methods that are used to train animals that take part in Walt Disney's films - rewarding the animals when they do as we want them to do, and ignore them if they do not. This is called positive reinforcement.
