In order to create a successful factory recirculating aquaculture system, it is necessary to comprehensively consider many aspects, such as the system configuration, special equipment and management system.
In addition, there are some seemingly ordinary parts that are easy for us to ignore: for example, the breeding environment of circulating water, which is carried out in an indoor environment or in a greenhouse.
So, why grow it indoors? It costs money to build greenhouses even outside? Today, we will explore this question.
Heat preservation and temperature control
Whether indoors or in greenhouses, the first important role is thermal insulation and temperature control. The traditional greenhouse, also known as the greenhouse, has the function of controlling light and temperature.
Different types of fish have different requirements for water temperature, generally speaking, tropical fish need water temperature between 24-30 degrees Celsius, while cold water fish need water temperature between 15-22 degrees Celsius.
Indoor or greenhouses can ensure that the water temperature in the breeding tank is stable and suitable, so that the fish can grow normally in winter.
In this way, the temperature problem of fish cross-season farming is not only solved, but also the breeding cycle and yield are significantly improved.
Shelter and protect water quality
Another important role of greenhouses is to shelter the wind and rain and protect the breeding environment.
Traditional soil pond farming methods are often vulnerable to extreme weather, such as high temperature baking, torrential rain, snow and freezing damage. In the past 24 years, extreme weather events have occurred in many parts of the world, and the aquaculture industry, as an industry closely linked to the natural environment, is the first to suffer a huge impact.
These adverse weather conditions will not only affect the water temperature of the aquaculture tank, but also damage the water quality, bringing stress reactions and poisoning risks to the fish. Many traditional fish farmers suffer and suffer heavy economic losses.
Indoor farming or by building greenhouses, can effectively prevent the interference of these external factors, protect the water quality and fish health in the aquaculture tank.
Prevent parasites and diseases
In addition to shelter from wind and rain and temperature control, greenhouses can also create a relatively closed environment for breeding ponds to effectively prevent the harm of parasites.
In outdoor farming environments, parasites easily enter the breeding tank through various vectors and quickly spread to all fish. In greenhouses, due to the relatively closed environment, the transmission of parasites is greatly limited, thus reducing the risk of disease outbreak.
Efficient farming in a controlled environment
The factory recirculating aquaculture system itself emphasizes the precise control of the farming environment. Through the construction of greenhouses, the controllability of the system can be further enhanced, and the comprehensive control of environmental factors such as temperature, humidity and light can be achieved.
This controlled environment farming method not only improves the growth rate and quality of fish, but also realizes the scientific management of species growth rate and harvest cycle, bringing higher economic benefits to farmers.
In summary, the reason why the factory recirculating aquaculture system needs to build greenhouses is mainly to maintain temperature control, shelter from wind and rain, protect water quality, prevent parasites and diseases, and achieve efficient farming in a controlled environment. In this way, it can be regarded as a real factory closed farming mode of circulating water.
