This paper based on field data (on red tide water quality monitoring at the Changjiang River mouth and Hutoudu mariculture area in Zhejiang Province from May to August in 1995, and May to September in 1996) presents an effective model for short term prediction of red tide in the Changjiang Estuary. The measured parameters include: depth, temperature, color diaphaneity, density, DO, COD and nutrients (PO 4 P, NO 2 N, NO 3 N, NH 4 N). The model was checked by field test data, and compared with other related models. The model: Z=SAL-3.95 DO-2.974 PH-5.421 PO 4 P is suitable for application to the Shengsi aquiculture area near the Changjiang Estuary.
