Water quality has an important impact on aquaculture. Therefore, it is particularly important for aquaculture to be familiar with the detection indicators, to conduct regular water quality inspections, and to respond to the adjustment of water quality indicators in a timely manner.
The main testing items for aquaculture waters include pH, ammonia nitrogen, dissolved oxygen, nitrite, sulfide, and salinity. Among them, dissolved oxygen and proper pH are essential conditions, while ammonia nitrogen, nitrite nitrogen and sulfide are the main toxic substances produced by fish and shrimp metabolism. Accurate and timely measurement of the concentration of these substances, and then taking corresponding measures can greatly improve the survival rate of fish and shrimp, and reduce the cost of breeding.
