||This study aimed to analysis the data of primary production, chlorophyll a and nutrient to realize the properties of the water surrounding Taiwan in climate changes. In this study will also build the data base of the primary production in this area. Meanwhile, Satellite ocean color data from the SeaWiFS and MODIS sensor were used to examine distribution of Chlorophyll a concentration around Taiwan for the period of 1978 through 1986. And primary production was also estimated with the vertically generalized production model of Behrenfeld and Falkowski (1997) by using the satellite SST and ocean color data. These satellite-derived chlorophyll and primary production was compared with the measured Chlorophyll and integrated primary production in field with 1998-2008, respectively. Its seasonal and annual variations were also evaluated with the index of climate change. In addition, this study will also build a relationship between the ENSO and water surface temperature from climate data base (1 x 1 degree) by statistical methods. Collecting the catch of fishery within 1998-2008, to realize the overfishing index changes.
