In order to promote the development of aquatic facilities and fisheries in the central region and improve the level of fishery modernization, on December 1-3, 2023, the Hunan Aquatic Development Forum and the 3rd Central (Changsha) Fishery Expo were successfully held in Changsha. With the theme of "Facility Fishery Boosts the High-quality Development of Hunan Aquatic Products", the forum gathered authoritative experts, entrepreneurs and fishery doctors from all parties in government, industry, research and media to share business innovation models, cutting-edge products, and R&D achievements under the new format, and jointly how to achieve the development and growth of the industry while achieving the healthy and stable development of the industry, and providing suggestions for creating a new pattern of the industry. Liu Shaochun, President of Yumeikang Group, Fan Junde, Assistant to the President and Director of the Science and Technology Department, Feng Xinglang, Director of the Technical Publicity Department, and Xiong Lei, Deputy Director of the Fish Varieties of the Zhanmeng Management Centerand so on. 
Xiong Lei, deputy director of fish varieties of the Zhanmeng Management Center of Yumeikang Group, was invited to give a keynote report"Open materials and functional materials help to raise good breeds and good sales". 
At the forum, Director Xiong gave a detailed introduction to the open bait - filter bait Duotai, functional material Yukangtai, fast shrimp feed, etc. It is reported that the filter bait Duotai is a dry powder fermentation material with 36 proteins, which can directly provide bait for the fry, and at the same time, the yeast and the medium are independently fermented and expanded in the pond to fully decompose and utilize the residual bait feces. At the same time, in the study of the open bait of Hefang crucian carp No. 2, it was confirmed that the filter bait Duotai could be used as the open bait of Hefang crucian carp No. 2, and the fry of Hefang crucian carp would ingest the filter bait Duotai within at least 5 days of opening. In a large number of practical applications, it has been shown that the bait Duotai can greatly improve the survival rate of hatchery splashes and crayfish seedlings, and the bait Duotai can improve the quality and efficiency of silver carp breeding at the same time. Director Xiong also emphasized that the experimental results of the functional material Yukangtai in colleges and universities show that adding a certain proportion of Yukangtai to the conventional feed can effectively reduce the bait coefficient of the fish, promote the growth of the fish, and at the same time play a role in preventing fatty liver, enteritis, and preventing the accumulation of fat in the body cavity of the fish, which reduces the incidence of grass carp to a certain extent. In addition, according to Director Xiong, the fast shrimp feed in the best-selling crayfish market has 6 black technologies and 3 top technologies, and it is the earliest fully cooked crayfish feed developed in the industry. It has the characteristics of ultra-fine grinding, high absorption rate and less waste. The vacuum post-spraying technology used effectively solves the problem of adding vitamins and bacteria to the feed, which is a unique technology in the industry. In the past ten years, Yumeikang Group has been using scientific research to support and emotionally load, and tirelessly empowering the development of China's aquatic industry. We will continue to strengthen scientific research and technology, improve the level of scientific research and innovation, pay more attention to practical results, and strive to transform the results incubated by scientific and technological innovation into practical results of high-quality development, so as to help farmers increase production and income. In order to realize rural revitalization and promote the high-quality and healthy development of the aquatic industry, contribute the wisdom and strength of Yumeikang people. Yumeikang Group, Zan 11
