The US Navy has reported that it will bring to an end its long running programme training dolphins to detect underwater mines.
The dolphin programme, which also involves dolphins trained to keep enemy swimmers away from warships, will come to an end within the next five years with the Navy stating that it will continue to care for the 24 dolphins it holds. What that care entails is not yet clear.
As newer, high-tech anti-mine capabilities are now used by the Navy it seems the dolphins are no longer of use.
Studies suggest that almost all US Navy dolphins were taken from the wild – probably around the Gulf of Mexico. Their capture is often brutal with only the young and fit individuals removed from the pod. The result is a stressful and negative effect on the group. They are then subjected to a life in captivity unable to travel the distances that they would in the wild each day. Causes of death for US navy dolphins include infections, gastric impaction (swallowing a foreign object), pneumonia, spinal fracture and drowning.
