In this paper, the changes of chlorophyll-a content in shrimp ponds along the coast of Huanghua from 1990 to 1992 were studied. The changes of chlorophyll-a content in shrimp ponds after 3 years and their characteristics were revealed. The relationship between chlorophyll-a content and red tide was revealed. This paper presents the use of chlorophyll a in shrimp ponds eutrophication threshold value of shrimp ponds in China to study the red tide has important reference value.
