| 中文摘要: |
| 为了研究网箱养殖对周边水环境和牡蛎生长的影响，于2012年6~8月对距深澳湾网箱区边缘0、20、50、100、200、500、1000m和EN0m的水质和牡蛎进行研究。水质监测结果表明，距网箱区边缘20m以内的水体中无机氮、无机磷和POM的浓度较50m以外的高。0m处的无机氮和无机磷的浓度最高，分别为16.11、1.01μmol/L，网箱边EN0m和0m处的溶氧最低；牡蛎的生长表明，网箱边缘0m处牡蛎壳高特定生长率为0.76%/d，显著高于50m以外的区域，网箱区20m以内牡蛎湿重的特定生长率高于50m以外的区域，但差异不显著。总体表现为网箱养殖对20m范围内水环境和牡蛎生长的影响较50m以外的区域大。 |

| Water environment and the performance of oyster（Crassostrea gigas）on 0m, 20m, 50m, 100m, 200m, 500m, 1000m and EN0m from cage fish farm in the Shenao bay was conducted from March to August 2012. The results showed that the concentration of inorganic nitrogen inorganic phosphorus and POM of water within 20 m of cage area edge were higher than 50 m outside. The inorganic nitrogen and phosphorus concentrations were 16.11 and 1.01 μmol/L on 0 m respectively, the dissolved oxygen was minimum on EN0m and 0 m. The shells high specific growth rate of 0.76%/d in cage area edge 0m, significantly higher than 50m outside, the wet weight specific growth rate within 20m of cage area edge were higher than 50m outside, but not significant. In general, the impact of cage fish farm within 20 m on water environment, particulate matter and the performance of oyster were greater than 50 m outside. |
