This paper deals with the surface temperature mapping of fishing grounds by the use of satellite data. A wide range of subjects of the fishing information in Kumano-Nada sea were discussed using the questionnaires from fishermen and records of satellite images received by Fisheries Research Institute of Mie. Temperature mapping of fishing grounds was carried out by the use of a computer. Results are summarized as follows; Satellite images of temperature profiles of fishing grounds have become to be widely used by coastal fishermen of Kumano-Nada sea. In the future, it is proposed that communication methods be improved in order to give out the information more quickly. Monthly receiving rate of available satellite images was significant for mean value of monthly cloudiness at Kumano-Nada sea; the number of available images received in the sea was 5 in 80 orbits (6.25%) in July and 28 in 78 (35.89%) in December 1987. Under ordinary conditions of Kumano-Nada sea, computer contouring was successful by the use of data estimated by satellite images. This contouring method is useful for the con-struction of data-base of hydrographical forecast of the fishing grounds.
