Abstract: We conducted the investigation in physical-chemical and biological factor of health-breeding earth-pond which cultured Portunus pelagicus、Penaeus japonicus and Ruditapes philippinarum. Here is our experimental results: the water temperature was between（17.5±1.7）℃ to （31.1±3.6）℃, the specific gravity of sea water was between （1.022±0.001）to（1.024±0.001）, the pH of sea water was between（8.0±0.2）to（8.3±0.1）. The value of water transparency was 52±7.9 cm, dissolved oxygen 6.76±0.18 mg/L, inorganic nitrogen 0.59±0.61 mg/L, labile phosphate 0.019±0.013 mg/L, substratum sulfide 59.2±43.4 mg/kg. The numbers of algae species were 23±5 in our earth-pond, the amounts of algae（1.08±1.16）×105 individals/L. There were 8 dominant species which were lack of abundance but stable in those populations. And moreover, the monthly growth curve of Portunus pelagicus、Penaeus japonicus and Ruditapes philippinarum with health breeding suggested that our breeding model was matured but also efficient. The model in our study can be demonstrated after technically integration and popularized in the future.
