Water quality management in aquaculture is one of the key factors in ensuring the healthy growth of fish and other aquatic organisms.Standard parameters for water quality testing usually include water temperature, dissolved oxygen, PH, ammonia, nitrite, sulphide and other parameters.The following section details the standard parameter list for aquaculture water quality testing.
Water temperature: 22°C-28°C1.
Fertilisation: 3-4 mg/L1.
Dissolved Oxygen: Dissolved Oxygen should be maintained above 5mg/L for freshwater aquaculture and greater than 75mg/L for marine aquaculture23.
pH: Ideal range is 6.5-8.5 for freshwater aquaculture and 7.0-8.524 for marine aquaculture.
Ammonia: Concentration should be less than 0.2 mg/L24.
Nitrite: Levels should be less than 0.2mg/L24.
Sulphide (hydrogen sulphide): Concentration (in sulphur) not to exceed 0.2mg/L24.
Total alkalinity: The appropriate total alkalinity for freshwater aquaculture ranges from approximately 75-200 mg/L5.
Total hardness: about 50mg/L for freshwater aquaculture and 80-120mg/L for marine aquaculture3.
Turbidity: 20-30 cm in the early stages of freshwater culture, 30-40 cm in the middle stages, and 40-60 cm in the later stages5.
The testing and control of these parameters is critical in aquaculture, and ensuring that water quality meets standards can reduce disease incidence and improve aquaculture success.
In practice, it needs to be adapted to the specific species being farmed and the local situation.In addition, regular monitoring of water quality and taking timely measures to improve it are important means of ensuring the success of aquaculture.
ERUN series aquaculture water quality tester for fish, shrimp, shellfish and algae fisheries developed and produced by Erun Group is a solution designed with reference to GB 11607-1989 Fishery Water Quality Standard.Fish, shrimp, shellfish and algae aquaculture water quality analyser can mainly be used to detect suspended solids, pH, dissolved oxygen, biochemical oxygen demand, total coliforms, mercury, cadmium, lead, chromium, copper, zinc, nickel, arsenic, cyanide, sulphide, fluoride, ammonia nitrogen, volatile phenols, petroleum and so on.The water quality testing equipment for fishery waters is suitable for testing the water quality of fishery waters in sea and fresh water, such as fish and shrimp spawning grounds, baiting grounds, wintering grounds, migratory corridors and aquaculture areas.
In addition to the above standard parameters for aquaculture water quality testing, there are other water quality indicators such as microorganisms, copper, mercury, cadmium, lead, zinc, nickel, arsenic, cyanide, fluoride, volatile phenols, etc. However, since these indicators are not routinely tested in all aquaculture scenarios, the specific scope of the standards is not listed here.However, these parameters can be detected by our instruments, if you need detailed product information, you can directly consult customer service.
