不同沉水植物对日本沼虾生长存活及水环境影响特征
Characteristics of different submerged macrophytes on the growth and survival of Macrobranchium nipponense and their effects on aquatic environment
摘要
Abstract
To reveal the effect of submerged macrophytes on the cultivation of Macrobrachium nipponense,a 90-day microcosmic experiment was conducted.The experiment aimed to simulate the cultivation system of three different macrophytes,namely Hydrilla verticillata(H),Potamogeton crispus(P),and Vallisneria natans(V),both individ-ual and in pairwise combinations.The emphasis was to evaluate the effects of these macrophytes on the growth,sur-vival,and aquatic environment characteristics of M.nipponense.The results of the experiment showed that the pres-ence of H.verticillata,and V.natans,and their combinations effectively enhanced spatial heterogeneity and main-tained water quality parameters,such as pH,dissolved oxygen(DO)levels,and water transparency.However,it was observed that the transparency of the H.verticillata and H.verticillate+V.natans groups significantly increased during the later stages of the experiment,while the chlorophyll a content significantly decreased(P＜0.05)in the later stage of the experiment.The survival rate of M.nipponense was found to be higher in the H.verticillata,V.na-tans,and their combination groups compared to the control group.Additionally,the shrimp's survival rate and bio-mass showed a significantly positive correlation with the biomass of H.verticillata(P＜0.01),indicating that the presence of H.verticillata significantly promoted the growth and survival of M.nipponense.Those findings provide val-uable insights for optimizing ecological aquaculture patterns and improving the overall quality and efficiency of M.nip-ponense cultivation.[Chinese Fishery Quality and Standards,2023,13(6):01-10]关键词
