A strongly salined coastal soil was reclaimed by fish culture with accumulated rain water together with additional irrigation using slightly salined river water. The rate of salt leaching was distinctly decreased after the salt contents of the soils declined to certain values. Two years later, in the same soils, a new culture model of mixed culture of fish and barley (MC)1) was set up and compared with only barley culture (BC)2) and with only fish culture (FC)3) to exame the effect of saline soil reclamation. The results obtained in the following three years were as follows. 1.The maximum rate of salt leaching, the biggest decrease of Na+/Ca++ and the distinct enrichment of Ca++ in surface soil (0-20cm) were obtained in the soils of MC. 2. Better soil fertility indexes, such as soil physical and chemical properties, could also be found in the soils of MC. Thus, soil organic carbon of MC was 1.48 times that of BC, the ability of nitrogen supply was in the order of MC>BC>FC, and the biggest activity of soil urease was obtained in the soil of MC, which was closely related to the fertility of coastal saline soil.
