摘要或動機

Water pollution is a severe problem for human beings. Sewage and hot water\r
coming from homes and factories have changed the environment for aquatic\r
animals. To manage a polluted environment, an accurately designed monitoring\r
system is needed that will detect signs of toxic material or increase in temperature as\r
fast as possible. A new and more accurate bio-monitoring system, which involves\r
actual creatures, needs to be developed to save the aquatic environment from\r
pollution.\r
This experiment focused on discovering a new way to monitor aquatic\r
creatures by observing the behavioral patterns of the medaka and observing how\r
they changed when exposed to external stress, especially an increase in temperature\r
or exposure to insecticide. The behavioral patterns of the medaka were observed and\r
measured by a tracking program called the Movement Viewer. In the transition\r
period, that is, when the temperature was raised from 25°C to 35°C, the total moving\r
distance of the medaka suddenly increased compared to that in 25°C. When the\r
medaka was in a temperature of 35°C, it slowly adapted to the new environment and\r
the total moving distance showed a similar value to that in 25°C. For section\r
dominance, the medaka showed a sudden increase in the dominance of the top part\r
of the tank, meaning that the medaka tended to swim on the surface of the\r
experimental aquarium. Again, it slowly adapted when the temperature had\r
completely changed to 35°C.
