广东珠江三角地区养殖水质监测与评价
Monitoring and Evaluation of Aquaculture Water Quality in the Pearl River Delta Region of Guangdong Province

对广东珠江三角地区30个池塘调查结果进行分析，了解不同养殖模式(品种)对池塘水体中总磷、总氮、硝酸盐氮、亚硝酸盐氮和氨氮含量的影响。调查结果显示，根据养殖模式的不同，池塘水体中的总磷、总氮、硝酸盐氮、亚硝酸盐氮和氨氮含量存在差异。其中，塘鲺养殖的池塘水体氨氮含量最高，四大家鱼和鹅混养的池塘水体总磷含量最高，而鱼类单养的池塘水体总氮和亚硝酸盐氮含量最高。通过分析不同养殖模式(品种)的水体营养物含量，可以为池塘养殖提供指导，优化养殖模式以提高水体质量和养殖效益。
The survey results of 30 ponds in the Pearl River Delta Region of Guangdong Province were analyzed, to understand the effects of different culture models (varieties) on the contents of total phosphorus, total nitrogen, nitrate nitrogen, nitrite nitrogen and ammonia nitrogen in pond water. The results showed that the contents of total phosphorus, total nitrogen, nitrate nitrogen, nitrite nitrogen and ammonia nitrogen were different according to the different culture mode. Among them, the ammonia nitrogen content in the pond cultured by pond beetles was the highest, the total phosphorus content in the pond cultured by four fishes and geese was the highest, and the total nitrogen and nitrite nitrogen content in the pond cultured by fish was the highest. By analyzing the nutrient content of different aquaculture models (varieties), it can provide guidance for pond aquaculture, optimize the aquaculture model to improve the water quality and aquaculture efficiency.
