| Research Abstract |
The temporal water area formed by rainfall provides important breeding environmentfor some fishes. Environmental research of the temporal water area and maturationinvestigation of fishes were conducted for the purpose of grasping the environmentalcapability and the physiological and ecological information of the fishes which breed in the temporal water area. Although the conspicuous feature was not observed in thewater quality of some temporary water areas, it was suggested that the plankton usedas the food for larvae of fish increased from a constant water area. Furthermore, it wassuggested that the breeding period of fish which breeds in the temporal water areacontinues comparatively long (spring to autumn).
