Tongwei Agricultural Development Co., Ltd. (hereinafter referred to as TWAD), a subsidiary of Tongwei Co., Ltd., focuses on feed production and aquaculture as its core businesses, while also engaging in aquatic seed breeding, aquaculture services, animal health, agricultural testing, fishery facilities and equipment, and financing and guarantee services. As of now, TWAD's annual feed production capacity exceeds 13 million tons, making it a leading global producer of aquatic feed and a significant producer of livestock and poultry feed. It operates over 80 subsidiaries and branches involved in feed-related businesses, with a production and sales network covering most regions of China and Southeast Asian countries such as Vietnam, Bangladesh, and Indonesia.

For more than 40 years, Tongwei has always adhered to driving sustainable development through scientific research. It has more than a dozen national and provincial technological innovation platforms such as the "National Enterprise Technology Center", "National Accredited Laboratory", "National-Local Joint Engineering Research Center for Aquaculture Animal Disease Prevention and Control Technology", "Key Laboratory of Aquatic Nutrition and Smart Aquaculture of the Ministry of Agriculture and Rural Affairs", "Key Laboratory of Aquatic Health and Smart Aquaculture of Sichuan Province", and "Sichuan Engineering Technology Research Center for Aquaculture". It has won the "Second Prize of the National Science and Technology Progress Award" five times, the "First Prize of the National Agricultural and Fishery Harvest Award" of the Ministry of Agriculture and Rural Affairs twice, the "First Prize of the Chinese Agricultural Science and Technology Award" of the Ministry of Agriculture and Rural Affairs, and the "First Prize of Sichuan Science and Technology Progress Award" and other honors.

As early as 1997, Tongwei was the first in the Chinese feed industry to establish and implement the Tongwei quality management system in accordance with the requirements of the ISO9001 quality management system. The on-site feed production management has been transformed from a disorganized, inconsistent, and personnel-dependent approach to a standardized, scientific, and coordinated modern quality management, and has been maintained for decades. In 2020, Tongwei took another step forward by revising its quality policies and objectives. Through a focus on "standardization construction", the company created core competitiveness by delivering the best product quality, lowest costs, and highest efficiency. This led to the automation of production, the digitization of business operations, and the standardization of processes, enabling Tongwei to achieve significant economies of scale in production and sales. The company's commitment to maximizing breeding benefits for users and pioneering a shift from "quality manufacturing" to a new "intelligent manufacturing" ecosystem has reshaped the feed industry.

At the same time, Tongwei established Tongwei Fishery Technology Co., Ltd. to develop aquaculture business. Tongwei Fishery plans to further focus on species with high market acceptance suitable for intensive aquaculture, such as whiteleg shrimp, largemouth bass and longsnout catfish, in the next 3-5 years, to explore the facility-based and industrialized aquaculture model under different aquaculture conditions. In this way, the Company will make technological breakthroughs and achieve scale and brand effects, to establish the competitiveness of Tongwei aquaculture industry chain system and lead the sector. As a result, Tongwei's position as a world-class leading aquaculture enterprise will be consolidated.
