However the water color is composed of suspended particles and plankton including zooplankton and phytoplankton, especially phytoplankton diversity may affect the ecological environment in water. The growth of organisms are related to the content of phytoplankton in culture pond. To understand the relationship between phytoplankton and water color. In present study for the Yunlin area 27 clams pond were analyzed water color, phytoplankton and water quality. The results showed that water color data of sample by PANTONE-CMYK Coaten can be found six color gradation in the all culture pond. The color gradation P178C and P177C (Grayish green) is the most common in water color data. The color gradation P178C has with dominant species include Nitzschia vitrea, Pleurosigma angulatum, Nitzschia closterium and the color gradation P177C has with dominant species include Nitzschia closterium, Pleurosigma angulatum, Nitzschia vitrea.There are 68 phytoplankton species were identified , the dominant species are 78% of Bacillariophyceae. In this study, PANTONE-CMYK Coaten was usde to compare the water color, to establish the basis and for water color, for improving and advancing the aquaculture technology.
