| Outline of Final Research Achievements |
The effects of water quality in the Tuul River in Mongolia on the genetic diversity of fish and animal health were investigated. The water in the Tuul River was more polluted downstream. In 2014, very high numbers of Escherichia coli were detected in well water. Pathogenic E. coli was detected in animal feces. Sheep and goats had high carriage rates. Cryptosporidium was detected in cattle feces and river water. In 2015, the numbers of E coli in well water decreased after changing the well structure. Sheep that drank water downstream had a higher rate of pathogenic E. coli infection. The genetic diversity of fish was similar to that of fish in Lake Baikal. Satellite image analysis showed that vegetation was better farther from roads. The regulation of well construction and the use of pastures may make the pasturing environment sustainable.
