On February 5, the first China Aquatic Seed Industry Expo opened in Nansha District, Guangzhou. Yu Kangzhen, Vice Minister of agriculture and rural areas, attended and delivered a speech. Provincial leaders Zhang shuofu, ye Zhenqin and Huang yebin, academicians of Chinese Academy of Engineering Lin Haoran, Mai Kangsen, Bao Zhenmin and Liu Shaojun, director Xu ruiyong and deputy director Zhu Xinping of Pearl River Fisheries Research Institute, researcher Lu Maixin and researcher Xie Jun were present.
At the new variety release site of Seed Industry Expo, the new varieties of Chinese soft shelled turtle "Zhushui No.1" and tilapia "Yuemin No.1" bred by our institute won the "2020 National Aquatic new variety certificate" issued by the conference. Later, Yu Kangzhen, Zhang shuofu, ye Zhenqin, Zhang Xianliang, Liu Yingjie and other leading experts visited our booth to learn more about the new varieties such as Zhushui 1 and Yuemin 1 and the new achievements of tail water management mode. They fully affirmed the cultivation and promotion of new varieties and new achievements of our institute in recent years, and encouraged us to make persistent efforts to promote the green and high quality of China's fisheries We should make greater contributions to development.
With the theme of "creating the future of aquatic core power seed industry", the Expo gathers the latest achievements of domestic aquatic seed industry innovation, takes the original improved varieties as the carrier, and takes good technology and good method as the extension and expansion, fully displaying new aquatic varieties, new technologies, new models and new equipment. The tilapia "Yuemin No.1" bred by Lu Maixin's research team of our institute has solved the problem that the production of single male tilapia seedlings needs hormone transformation at present. In the process of seedling cultivation, the natural male rate of tilapia reaches 98.31%, which is suitable for large-scale production and Cultivation in the artificial and controllable fresh water body of the main tilapia production areas in China. The growth speed and meat yield of tilapia are improved, and the quality and quality of tilapia can be improved The purpose is to increase agricultural production and income. Zhushui No.1, a Chinese soft shelled turtle bred by Zhu Xinping's research team, takes growth rate as the target character. Under the same culture conditions, compared with the local unselected Chinese soft shelled turtle, its growth rate is increased by 12.3% on average. It is suitable for breeding in artificially controlled fresh water bodies in the south of the Yangtze River, such as Guangdong, Guangxi and Jiangxi.
