在四川省泸州市江阳区江北镇太阳岛养殖基地，一尾尾活蹦乱跳的鲈鱼苗在水中攒动，呈现出一幅现代 水产养殖新图景。作为泸州首例高密度养鱼项目，这里正以创新模式"游"出产业增效、农民增收的新路 径。 "每立方米水体能养100多斤鱼苗，是传统养殖的数倍。"太阳岛养殖基地总技术员王国强捞起鱼苗介 绍。在8个养殖大棚里，每个棚容纳120余万尾鱼苗，高密度养殖模式让有限空间释放出巨大产能。出鱼 时，工人层层传递满盆活鱼的场景，成为基地丰收的生动注脚。目前，该基地鱼苗主要销往云贵川三 省，因种苗优质，赢得了各地养殖户的青睐。 水质是高密度养鱼的"生命线"。为确保"好水养好鱼"，基地自主研制排污吸污设备，针对本土鱼类特点 自研菌种，并通过高位池循环过滤养殖用水，形成一套完整的水质保障体系。同时，动态调控水中含氧 量，让鱼苗在"氧足水净"的环境中健康生长，为高密度养殖奠定了坚实基础。 "这是泸州首例高密度养鱼项目。"该基地负责人舒一波谈及项目时充满自豪，政府的政策支持与补助为 产业发展注入了强心剂，让他更有底气探索规模化养殖之路。除了鲈鱼，该基地还引进鲟鱼、鳜鱼鱼 苗，计划与镇上养殖户分享技术经验，通过多元化养殖拓宽产业边界，让" ...

Core Insights - The report by Yunmanman highlights the digitalization of agricultural logistics in Jiangsu, showcasing a high mechanization rate of 87% and an informationization rate of 51.2% in agricultural production [1] - Jiangsu's agricultural supply chain is characterized by high mechanization, strong regional collaboration, and intelligent integration, transforming farmers from traditional practices to more efficient methods [1] Group 1: Agricultural Machinery - Jiangsu's spring farming shows a trend of local supply dominance, with most agricultural machinery products sourced from within the province, particularly from cities like Suzhou, Wuxi, and Changzhou [1] - The focus in Suzhou is on technological innovation, developing fully automated high-density vegetable transplanting machines and unmanned electric tractors, leading in the Yangtze River Delta region [2] - Wuxi specializes in intelligent and specialty agricultural machinery, with high domestic market shares for products like unmanned plant protection drones and automatic rice transplanters [2] Group 2: Aquatic Seed Transportation - Jiangsu is a key player in the national aquatic seed supply chain, with significant transportation of fish, shrimp, and crab seedlings to other provinces, particularly from cities like Nantong and Yancheng [2][3] - Yancheng is recognized as the "hometown of crab seedlings," contributing to 70% of the national supply, while Nantong produces over 100 tons of crab seedlings annually [2][3] - Suzhou is also involved in breeding special aquatic seedlings, with products reaching provinces like Fujian and Shandong [3] Group 3: Agricultural Resource Distribution - The distribution of agricultural resources in Jiangsu exhibits a "two-way flow" characteristic, with fertilizers primarily sourced from Shandong, Hubei, Henan, and Anhui [3] - Key cities supplying fertilizers to Jiangsu include Linyi, Xinxiang, and Jincheng, while local seed supply is bolstered by inputs from Gansu and Shandong [3] - Yunmanman plays a crucial role in matching agricultural resource transportation needs with logistics, enhancing efficiency through real-time data management [3][4] Group 4: Digital Logistics Infrastructure - The digital logistics platforms like Yunmanman are becoming essential infrastructure for optimizing the agricultural supply chain and improving spring farming efficiency [4] - The integration of intelligent upgrades in agricultural machinery and nationwide distribution of aquatic seedlings contributes to a robust material foundation for spring farming in Jiangsu [4]
