| Outline of Final Research Achievements |
The aim of this study was to understand the mechanism of how the mud snail and temperature affect biotic factors of other aquatic organisms and performance of rice plants. The presence of mud snails resulted in significantly increased plant height and SPAD value of the rice plants, although the tiller number was not significantly affected. The results suggested that the effects of temperature differed among plant performances; plants grew taller but had fewer tillers when the rice was grown at high temperature, while SPAD was not significantly affected.
The experiments to understand the effects of temperature and mud snails on the biotic factors of other aquatic organisms suggested that temperature did not affect biotic factors of other aquatic organisms, while it influenced on abiotic factors. On the other hand, the effects of snails differed from the temperature effects; the snails gave much influence on the biotic factors than abiotic ones.
