The seawater factory aquaculture system is mainly aimed at high-quality, high-density, and high value-added varieties. Such as grouper, shrimp, abalone, etc. In order to cope with external factors such as water source pollution and weather changes, the aquaculture system is set up indoors. Treat the water according to the actual needs of the aquaculture species. In order to achieve comprehensive benefits of high density, high efficiency, low cost, low pollution, automation, and off-season. The seawater fish recirculating aquaculture system is mainly aimed at high-quality, high-density, and high-value added varieties in the seawater factory aquaculture system. Such as grouper, shrimp, abalone, etc. In order to cope with external factors such as water source pollution and weather changes, the aquaculture system is set up indoors. Treat the water according to the actual needs of the aquaculture species. In order to achieve comprehensive benefits of high density, high efficiency, low cost, low pollution, automation, and off-season.
The seawater factory aquaculture system includes subsystems such as mechanical filtration system and biochemical filtration system. The core is a biochemical filtration system. Because the amount of water changed is very small or not changed. Excessive aquaculture density can lead to a sharp increase in ammonia nitrogen and nitrite in the water. Utilize equipment such as microfilters and protein skimmer to filter out solid suspended substances such as fish and shrimp feces in the first time, avoiding these substances from becoming toxic substances in water due to the decomposition of bacteria. The decomposed ammonia nitrogen and nitrite can cause fish and shrimp to die from hypoxia or poisoning. We use the method of placing filter media in a biofilter and cultivating beneficial bacteria to decompose ammonia nitrogen and nitrite in water.
Because the protein skimmer has a large number of bubbles in the water during operation, it has a strong oxygenation effect. Therefore, in the presence of a protein skimmer, it is possible to consider not using oxygenation equipment.
The constant temperature system can use a heat pump or a chiller. Some places in the north also have automated boilers. When configuring constant temperature equipment, the insulation conditions of the factory building and fish pond should be considered. Moreover, the constant temperature device cannot heat or cool the water body to the target temperature at once during operation, but gradually increases the overall temperature of the water body to the desired temperature through multiple cycles.
In terms of sterilization, ozone and protein skimmer are used together, and the proteinskimmer also serves as an ozone mixing tower. But due to long-term cycling, ozone can have a negative impact on biofilters. Therefore, for long-term operation of recirculating water systems, we recommend using ultraviolet sterilizers to sterilize and disinfect the water.
Appropriate salinity is crucial for marine aquatic organisms. Especially shrimp and crabs. Because they require a large amount of minerals to maintain their shelling needs. Therefore, maintaining the concentration of various types of ions in water is one of the important tasks.
There are many factors that affect the pH value. Including dissolved oxygen, algal phase, temperature, etc. Therefore, maintaining a dynamic balance of pH value is an important condition for maintaining good biological growth.
Most aquatic organisms are under stress to drastic changes in water indicators. The balance and controllability of various indicators of the water body, as well as the qualification of key indicators, are the core contents of the seawater factory aquaculture system.
During the design phase, the system should take into account the customer's on-site situation, breeding density, and other conditions, and comprehensively consider maximizing energy conservation and environmental protection. And can generate maximum production efficiency.
