Selection of site is one of the mostimportant factors for .success of coastal aquacultural farm. A suitable site is the one that provides optimum conditions for the growth of the species cultured at the targeted production level. Soils with high water holding capacity to make feasible earthen pond construction and to prevent losses due to seepage in the ponds are desirable. Texture, bulk density, organic matter and specific gravity determine-to a large extent the water retention by soil. The retention and release of water by soil is a direct functional arrangement of soil aggregates and their porosity (Nagar et ai., 1995). The present study was undertaken to assess the water holding capacity of coastal soils in-relation to different properties of soil.Six soil samples were collected from each of three coastal areas, viz., Muttukadu (Chengai M. G. R. district; Tamil Nadu), Nellore (Pattapalem and Chemarayanapalem villages of Bogulu mandal) and Kakinada (Bhairavipalem village) of Andhra Pradesh. The composite soil samples collected from each area were air-dried, powdered and then sieved for further analysis at the laboratory. The bulk density, specific gravity, porosity, void and water holding capacity ratio of the soil samples were analyzed by the methods described by Richards (1960). The liquid limit of soil was determined with the help of standard liquid limit apparatus designed by Casagrande (Punmia, 1990). The soil passed through 420 micron sieve was used for the determination of liquid limit and the ASTM tool was used for making grooves for sandy nature of soils. Soil textural analysis was done following the method described by Piper (1966). Six soil samples were collected from each of three coastal areas, viz., Muttukadu (Chengai M. G.
