Research Abstract

In this study, authors have examined the inhabiting environment of loaches, the primary diet for crested ibis (Nipponia nippon) that is to be reintroduced into the wild in 2008. In the course of the examination, we have attempted to comprehend the distribution and abundance of loaches in agricultural canals and paddy fields. According to our survey, the following observations and findings have been noted: 1. A large number of loaches exits even in the sloped streams with waterfalls and drop works of the study area. Those loaches are supplied from upper swampy terraced paddy fields, and stay in stream sections with baskets of stones or piers of log. These structures create pools of deep, slow-velocity water where loaches can find refuge when floods occur. The effect of baskets of stones was verified in an experiment. 2. With regard to paddy field structure, loaches show a strong preference to paddy field with catchment ditches, commonly found in Sado Island. Upon this finding, authors h … More ave proposed to make catchment ditches with 50cm width and 30cm depth beside upper paddy fields in terraced paddy areas. 3. Loaches and other species are unable to leap over gaps between outlets of paddy fields and drainage canals created as a result of land improvement constructions. Generally, the elevation gap is designed to be at least lm for facilitating the gravity drainage of undrerdrainage systems. To reduce the elevation gap, authors suggested embedding perforated catch pipe separately when land improvement construction would be undertaken. 4. Authors also proposed to use corrugated tube as a fishway bridging the gap between paddy field and drainage canal for the areas where land improvement had already completed. Due to its flexibility, corrugated tubes present significant application and cost advantages. In the laboratory experiment, it has been proven that loaches are able to migrate with extremely small discharge.
Furthermore, authors have presented the necessary conditions of paddy field in the case of bio-friendly deep ponding water cultivation, and the influence of nutrient salts used as fertilizer by various cultivation methods on Hachirogata district. Less
