          摘要:

          為揭示沉水植物對日本沼蝦(Macrobrachium nipponense)生長過程影響效應,進行為期90 d的微宇宙控制實驗,研究輪葉黑藻(Hydrilla verticillata)、菹草(Potamogeton crispus)和苦草(Vallisneria natans)單獨及兩兩組合的種植系統對日本沼蝦生長存活及水環境變化的影響。結果顯示,輪葉黑藻、苦草及其組合能較好地提高系統空間異質性,且水體pH、DO及水體透明度均保持在較穩定波動范圍,但輪葉黑藻及輪葉黑藻+苦草組后期透明度明顯升高、葉綠素a含量顯著下降(P<0.05)。輪葉黑藻、苦草及其組合中日本沼蝦存活率高于對照組,且蝦存活率及生物量與輪葉黑藻生物量呈極顯著正相關關系(P<0.01),表明輪葉黑藻對日本沼蝦生長存活具有顯著促進作用。本研究可為草蝦共作生態養殖模式的優化及日本沼蝦養殖提質增效提供依據。[中國漁業質量與標準,2023, 13(6):01-10]

          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 individual and in pairwise combinations. The emphasis was to evaluate the effects of these macrophytes on the growth, survival, and aquatic environment characteristics of M. nipponense. The results of the experiment showed that the presence of H. verticillata, and V. natans, and their combinations effectively enhanced spatial heterogeneity and maintained 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. natans, and their combination groups compared to the control group. Additionally, the shrimp's survival rate and biomass 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 valuable insights for optimizing ecological aquaculture patterns and improving the overall quality and efficiency of M. nipponense cultivation.
