"Fried concept cut leek!"
"What high technology? Isn't it indoor fish farming? "
"I heard that the input cost is so high that ordinary farmers can't afford to play!"
"Can this model really make money? Or is it just a gimmick for capital hype?"
...
In recent years, a model called "factory recirculating aquaculture" has caused controversy in the aquaculture industry. Some call it "the future direction of fisheries", while others dismiss it as "the pseudo-concept of cutting leeks".
What is the truth? Let's try to make sense of it.
What is factory recirculating aquaculture?
In short, this is a high-density farming model that "artificially simulates natural ecology" :
In the closed space, through physical filtration, biological purification, sterilization, constant temperature oxygen and other technologies to achieve the recycling of water resources.
The core goal is to get rid of land and water constraints and solve the problems of pollution, disease and climate dependence of traditional farming.
Factory recirculating aquaculture is not just an idea, it has already achieved remarkable results in several regions:
As a leading aquaculture company in Israel, Dagon uses RAS technology to achieve efficient and sustainable fish farming with an annual production of 3,000 tons. Its hatcheries produce 26 million fish fry a year, ranging from European perch to golden snappers.
Japan's Uninomics, in partnership with Maruyama Suisan, has built the world's largest RAS urchin farming facility with an annual capacity of 34 tons. Its technical feature is the use of sustainable kelp scraps as feed, to achieve stable output throughout the year
What are the advantages over traditional farming?
1. Water saving and environmental protection
The traditional farming mode consumes a lot of water resources and easily causes environmental pollution. The industrial recirculating aquaculture greatly reduces the waste and pollution of water resources through the recycling of water.
2. High efficiency and high yield
Recirculating aquaculture can achieve high-density aquaculture, and the yield per unit area is 10 times that of traditional ponds. At the same time, through the intelligent monitoring system, farmers can adjust the water quality and feeding amount in real time, and further improve the breeding efficiency.
3. Weather proof
Traditional farming is greatly affected by weather and extreme weather. Recirculating aquaculture is not limited by natural temperature conditions, year-round production, multi-stubble farming, balanced listing, and short breeding cycle.
4. Strong risk resistance
Traditional farming is susceptible to weather, disease and other factors, while factory farming effectively reduces these risks through a closed environment and intelligent regulation.
Of course, factory aquaculture also faces some challenges and problems.
For example, the initial investment is high, and some funds are needed for equipment procurement and system construction; Strict technical requirements, involving water quality control, equipment maintenance and other links, put forward higher requirements for the professional ability of farmers; In addition, the risk of disease transmission may be amplified in a closed environment.
However, these problems are not insurmountable. With the continuous progress of technology, initial investment and operating costs are gradually reduced; At the same time, the accumulation of management experience and the improvement of industry standards have also made epidemic prevention and control more efficient.
It is foreseeable that factory aquaculture will play an increasingly important role in future food production, providing a strong support for global food security and sustainable development.
In general, factory aquaculture is not only not an IQ tax, but an efficient and environmentally friendly way of food production in line with the development trend of modern society. It provides new ideas and methods for solving global food security problems through scientific and technological innovation and scientific management.
