Abstract: Abstract：It has been reported that community structure of crustacean zooplankton have been used as an indicator of trophic status. Many researches focused on inland natural waters, such as lakes and reservoirs. Differ in densities and macrophytes, the culture models and water environments were different in Trionyx sinensis cultured-pond. In the study, physical-chemical parameters and crustacean composition of four T.sinensis pond-cultured models were investigated from July to October and their correlation with trophic status was analyzed. The results showed that the DO, NH₄⁺-N, NO₂^--N, TN, TP, COD, Chl a and TLI of T. sinensis monoculture model were significantly higher than those of T.sinensis-Nelumbo nucifera, T.sinensis-ecology and T.sinensis-Trapa acornis model, while the SD of T.sinensis monoculture model were significantly lower than those of T.sinensis-Nelumbo nucifera, T.sinensis-ecology and T. sinensis-Trapa acornis model (P<0.05). A total of 7 species to 6 genus of cladoceran, 3 species to 3 genus of calanoid and 6 species to 6 genus of cyclopoid were recorded in all four models. Their conjoint dominant species were Paracyclops fimbriatus, Mesocyclops leuckarti and Thermocyclops taihokuensis. Cluster analysis showed that the T.sinensis monoculture model was divided into one group, and the T.sinensis-lotus model, T.sinensis-N. nucifera and T.sinensis- ecological model were grouped into one group. The abundance of cladocera was shown to be negatively related to TLI (P>0.05), the abundance of calanoid was positively related to TLI (P>0.05), and there was a significant positively correlation between the abundance of cyclopoid and crustacean and TLI (P<0.05); RDA showed that Chl a, NO₂^--N, SD, WT and COD significantly affected the composition of zooplankton crustacean (P<0.05). Our findings can not only provide technical guidance for the development of pond culture model of Chinese soft-shelled turtle, but also provide theoretical support for the study of fishery production affecting the structure and function of freshwater ecosystem.
