Why build a land-based ecological industrial park?

economic performance
The average annual revenue is 33 million yuan, and various performance indicators indicate that the project is expected to achieve significant surplus accumulation, good returns, and sustainable development

social results
Due to various factors such as ecological environment, cultivation environment, and germplasm degradation, the economic benefits of fishery production in Qinzhou Port have gradually declined. In addition, consumers' increasing attention to product quality and safety, as well as constraints such as reduced land resources, have made it difficult for traditional aquaculture methods to keep up with the pace of market development. Developing efficient, high-quality, and safe ecological fisheries has become an inevitable trend in the development of modern fisheries, and industrialized circular aquaculture is one of the important ways to achieve this. Therefore, in order to achieve sustainable development of the Qinzhou Port fishery, it is necessary to follow the trend, and developing industrialized circular aquaculture can become a way to break through the bottleneck of Qinzhou Port fishery development.

ecological benefit
The construction of a land-based digital ecological aquaculture demonstration base in Guangxi can effectively improve the aquatic ecological environment, control disease occurrence, enhance factory aquaculture productivity, and reverse the current passive situation of inefficient operation in aquaculture through the interaction, mutual restraint, and mutual influence between aquaculture organisms and the ecological environment, as well as the control, cleaning, and degradation of pollution processes and pollutants in aquaculture itself.

Introduction to Jingyu Technology Enterprise
Jingyu Technology was initiated and established by like-minded partners such as a PhD in Oceanography from Xiamen University and Ocean University of China. Jingyu Technology has reconstructed a leading circular aquaculture system in terms of energy consumption both domestically and internationally through first principles. We have more than ten core patents and technologies in supporting water quality treatment, fish feed extraction, formulation, fish genetic breeding technology, and tailwater discharge. Adopting technologies such as genetic breeding and large-scale Internet of Things to upgrade and transform traditional agriculture. Based on the concept of sustainable ecology, the company integrates concepts such as rural revitalization, carbon neutrality, digital agriculture, and seedling breeding. The company has been established for three years and has received three consecutive rounds of venture capital to support project development

Case Presentation

Fuzhou University&Jingyu Technology Industry University Research Base
This base is an industry university research base for Dongfeng snail circular aquaculture, which is a deep cooperation between the School of Biological Sciences and Engineering of Fuzhou University and Jingyu Technology; To solve various unexpected problems that limit the cultivation of Dongfeng snails, Jingyu Technology has developed a circulating water aquaculture system for Dongfeng snails based on first principles and more than ten existing patents and technologies. The single system covers an area of one acre, including two breeding ponds, a breeding area of 500 square meters, a filtration equipment area of 120 square meters, and a road area of 30 square meters. Mature industrial products are used for system assembly, which is only 30% of the cost of traditional circulating water systems. The cost per acre is basically the same as the circulating water subsidies in various provinces. Moreover, the cultivation of Dongfeng snails in this system will not cause pollution because during the operation of the system, biotechnology is used to absorb and degrade pollution, and the discharged effluent meets the effluent discharge standards.

Benxi National Salmon Breeding Farm of the Ministry of Agriculture
Covering an area of 150 acres, this is a national level rainbow trout breeding farm. The indoor recirculating aquaculture system for parent fish was designed by Professor Timmons from Cornell University in the United States. Professor Timmons is the President of the International Association for Recirculating Water and the founder of the theory of recirculating water.
The funding from the Ministry of Agriculture this time is for the localization improvement of Professor Timmons' design, with the construction of four new water systems totaling 12000 cubic meters, each with an energy consumption of 30kw.

Qingdao Guoxin Yantai Salmon Farming Base
Covering an area of 260 acres, it was formerly known as the Yantai branch of Dongfang Ocean, a domestic listed company. This project is one of the earliest circular water aquaculture salmon projects in the world, and has played a key role in cultivating domestic circular water talents. The core team of this project is the partner of Jingyu Technology. This project was fully acquired by Qingdao Guoxin for 226 million yuan in 2020, supporting the big ocean strategy.

Beijing China Electric Power National Sturgeon Breeding Farm
Covering an area of 420 acres, it is a national level sturgeon breeding farm with over 1000 sturgeon species. It has established more than 20 sets of circular water aquaculture systems, developed a system suitable for the demand of the northern market for aquatic products based on the characteristics of the northern environment, and upgraded and transformed for insulation and climate in the north. The comprehensive cost of breeding is lower than that of surrounding peers. The development of this project will drive surrounding breeders and breeding enterprises to upgrade their industries

Australian lobster circulating water temporary aquaculture export base
The annual catch of marine lobsters in Australia is about 20000 tons, which is a huge quantity. The vast majority of them are used for export. Therefore, it is very important to temporarily raise lobsters around airport cargo terminals and ensure survival rates. At the same time, the temporary storage space is compact and foreign labor is expensive. In response to the situation in Australia, this project has designed a forklift type circulating water tank, which can be independently operated by one person and can be stacked in multiple layers, greatly utilizing space.

Shanwei Grouper Seedling Farm
The Shanwei project aims to address the high infrastructure costs of the Foshan project by adopting a low-cost industrial solution for renovation and production of marine fish fry. It covers an area of 25 acres and is equipped with source water treatment, SS rotifer cultivation, algae workshop, and fish fry workshop to eliminate pathogens. It is expected to produce 500000 grouper white fry per batch.

Foshan Sea Bass and Mandarin Fish Circular Aquaculture Base
Foshan is the MVP model used for project feasibility verification at the beginning of the establishment of Fine Fisheries Science and Technology. In view of the high energy consumption cost of circulating water aquaculture at that time, a new circulating water system was designed by integrating the circulating water technology of Cornell University in the United States and the specific domestic conditions. Through cultivation tests, the cost of cultivating California perch and crispy tilapia was basically the same as that of traditional cultivation mode. However, Foshan also found some problems, such as high infrastructure costs, too long payback period, and serious problems of using agricultural greenhouses for heat preservation. Related problems were improved in the new fine fisheries project one by one.
