Japan is the second largest fishery country in the world, with a developed fishery economy, and rich fishing culture. In addition, the Japanese mainly eat fish. So many local residents want to engage in aquaculture industry. However, because of the scarcity of natural land resources in Japan, they only want to engage in aquaculture in coastal areas, so many people are at a standstill.



This case is a Japanese customer engaged in construction industry. He wants to develop aquaculture industry. He sees that the situation of factory recirculating aquaculture is steadily improving, so he wants to do indoor recirculating aquaculture at home. This is the first and only indoor recirculating aquaculture system in Guangzhou, which is built by GuangzhouZhonghang.

日本循环水养殖系统.jpgIn June 2017, customers contacted us through the Internet and came to our company to visit and understand the equipment of circulating water system. They told us: "Fisheries are developing towards modernization, intensification, scale and organization, and the industrial structure is more optimized. Considering the present policy and future development of fisheries, they resolutely decided to cultivate circulating water. This is the first time that he has switched to circular aquaculture. He wants to be in the forefront of the local circular aquaculture and let more people know about the circular aquaculture system. "Accompanied by our technicians, our customers fully understand the performance of the equipment, and have certain recognition of our equipment and production technology. After the first visit to the factory, they immediately reached an agreement with us.

After half a month, our company finished the production of all the equipment. After communicating with customers about the site preparation, we immediately contacted the truck for loading. At the same time, loading also stimulated the enthusiasm of workers. In a short time, we finished loading all the equipment, and then shipped immediately.



In mid-August, the system arrived in Japan intact. Our company sent technicians to the scene to assist in the installation of the system. There are all kinds of installation tools on the spot. With the concerted efforts of all of us, the system has been installed in a short period of 5 days, which makes us feel no sigh about the efficiency of Japanese work.

At the completion of the system installation, Japanese customers come to the seaside early in the morning to extract seawater and make artificial deployment of seawater. The deployed seawater is put into the system for pre-culture, so that the system can balance autotrophic bacteria and heterotrophic bacteria, and then slowly increase the amount of aquaculture to meet the normal aquaculture standards.

The system is not only environmentally friendly but also energy-saving. It is of great significance to reduce water pollution, improve aquaculture process and improve the utilization rate of aquaculture water. Although the customer is the first time to enter the field of recirculating aquaculture, the customer said that due to the first aquaculture, first from the medium and high density, such as stability and proficiency, then slowly increase the density.

Industrialized recirculating aquaculture system is an important way to control water environment actively by means of industrialization. It has small water consumption, less land occupation, less environmental pollution, high quality and safety of products, fewer diseases, high density, no restriction and influence of region or climate on aquaculture production, high utilization rate of resources, high input and high output, and low risk to realize sustainable development of aquaculture industry. Industrial recirculating aquaculture adopts intensive production mode, which reduces manpower cost and bait coefficient, improves the quality of aquaculture varieties by more environmentally friendly aquaculture mode, and achieves better product price and economic benefits. Nowadays, Japanese consumers are increasingly demanding high-quality aquatic products. The aquatic products produced by traditional aquaculture methods do not have much additional value space. They have small profits and high risks, and are difficult to meet the needs of local high-end consumers.

After a year or so, customers have mastered some basic technology and accumulated some experience. They are ready to expand their breeding scale. They come to our company again in July this year to discuss with our technicians. At present, another system has been ordered. We will work with customers to enter large-scale factory recirculating aquaculture. Guangzhou China Airlines has been committed to providing a safe, healthy and efficient new aquaculture model, and create a bright future of green and environmental protection with customers.
