Abstract: Intensice pond culture and“cultivate Hydrilla verticillata and breeding shrimp”are the two most typical culture models of macrobrachium rosenbergii in Guangdong province. This study was invetigate to comparative the effects of two cultrue molels on growth performance，body composition，muscle amino acid composition and economic benefit of M.rosenbergii. The results showed that the final body size，condiction factor and freshness of M. rosenbergii produced under the two cultrue models including intensice pond culture and“cultivate H. verticillata and breeding shrimp”had significant difference.The contents of crude protein and calcium composition in the whole body， essential amino acids，flavorable amino acids and total amino acids in the shrimp muscle under the“cultivate H.verticillata and breeding shrimp”model were significantly higher than those under the intensice pond model. The income，net profit，input􀆼output ratio and cost profit margin of“cultivate H. verticillata and breeding shrimp”model were obviously higher than that of the intensice pond model. These results indicated that the M. rosenbergii produced under the the“cultivate H. verticillata and breeding shrimp”model is more in line with the taste of producers and consumers，and it is suggested to adopt it in production practice and promote it. The results provided a reference for the selection of culture mode of M. rosenbergii.

摘要： 池塘单养和“种茜养虾”是广东省罗氏沼虾最典型的两种养殖模式。该文以罗氏沼虾为研究对象，比较分析了池塘单养和“种茜养虾”两种养殖模式下罗氏沼虾的生长性能、体成分和肌肉氨基酸组成以及养殖经济效益的差异。结果显示，与池塘单养模式相比，“种茜养虾”池塘养殖模式产出的罗氏沼虾个体规格、肥满度和肌肉新鲜度优势显著。“种茜养虾”池塘养殖模式罗氏沼虾体成分中的粗蛋白质和钙含量，肌肉中必需氨基酸、呈味氨基酸和总氨基酸含量明显高于池塘单养模式。“种茜养虾”模式的收益、净利润、投入产出比和成本利润率均明显高于池塘单养模式。综上“种茜养虾”模式产出的罗氏沼虾更符合生产者和消费者品位。研究结果为罗氏沼虾养殖模式选择提供参考。
