Abstract

This study analyzed the water environment of an artificial deep pool (ADP), underground type fish shelter installed in shallow pond, during late spring to summer season. The inside of ADP was stable daily water quality fluctuation and it was suggested as shelter space for fish when high water temperatures persisted in open water space. Analysis of St. 1 and St. 2 statistically indicated that, they were distinctly different spaces, with respect to water temperature, pH, DO, and conductivity (two-way ANOVA, P＜0.05). It was determined that these water environment conditions can affect the inhabitation and spawning of fish in shallow ponds. In the study area, Rhodeus uyekii was dominant and it was determined that an appropriate spawning temperature (16.5~18.5 ℃) for Rhodeus uyekii was formed, due to the use of an ADP. Ultimately, since ADP can maintain a steady temperature that is lower than the external temperature during summer, it can serve as good shelter for types of fish that are sensitive to high temperature or temperature fluctuations.
