Abstract

Bao Thang district is the largest source of aquatic products for Lao Cai province and some neighboring provinces. Water supply for aquaculture in the district is affected by many pollution sources: daily life, industry, agriculture (crop, livestock) and aquaculture activities in ponds. feed. Therefore, it is necessary to conduct an assessment of the current status of water quality for aquaculture, from which there are solutions to improve the production and quality of aquatic products in the district. In this study, the survey method was used to collect information about water sources and analyzed samples of water sources to assess the quality of water environment supplied to aquaculture ponds. Research results show that aquaculture water supply in Bao Thang district includes slit water, spring water, rain water and water from irrigation lakes in the area; 72.56% of the surveyed households said that the source of water is directly from the source into the household's aquaculture pond; 100% of households do not treat the water supplied to the fishponds; 54.29% of the surveyed households did not use treatment equipment in their ponds and 75.71% of the surveyed households did not use inoculants in the process of raising fish. The current status of water quality for aquaculture in Bao Thang district basically meets QCVN 08-MT:2015/BTNMT (Column B1). Locally with organic matter pollution, suspended sediment and high iron content.
