Applications/Examples of results

Wild pigs, brought in by humans, have become feral and are breeding, leading to problems with egg predation by these wild boars. The predation rate averaged about 60% along the entire coast, reaching as high as approximately 80% in some areas. As a countermeasure, electric fences designed to keep wild boars away from farmland were installed. In March 2001, electric fences were set up along a 1,600-meter stretch of coast where the predation rate was highest, and in July, an assessment showed that the predation rate dropped from an average of 83% along the entire coast to 24%, and in the areas with electric fences, it decreased from 83% to 8.8%. Additionally, in July 2002, the electric fence was extended by another 800 meters, and in September, a survey revealed that the predation rate had successfully decreased to 11% on average along the entire coast and to 7% in the areas with electric fences. Although there were damages from a tsunami, the system is still functioning without issues and is contributing to an increase in the number of hatchling turtles returning to the sea.
