从“凭经验”到“靠科技”，虾农拜师博导实现效益飞跃

Core Viewpoint - The article highlights the successful development of the freshwater shrimp farming industry in Xi Pu Village, Fujian Province, focusing on the cultivation of the Pacific white shrimp (Penaeus vannamei) and the introduction of innovative farming techniques to enhance productivity and profitability [1][3]. Group 1: Farming Practices - The farming area for Pacific white shrimp in Xi Pu Village exceeds 600 acres, contributing an annual output value of approximately 40 million yuan [1]. - Farmers conduct a 24-hour water quality test before introducing shrimp fry, with a survival rate above 95% indicating suitable water conditions for shrimp growth [2]. - Key water quality indicators such as dissolved oxygen, pH, ammonia nitrogen, and nitrite levels are monitored daily to ensure optimal conditions for shrimp farming [2]. Group 2: Technological Integration - A collaboration with Xiamen University’s Fisheries College has led to the establishment of a "Shrimp Technology Academy" in Xi Pu Village, providing technical support and training for local farmers [3]. - Training sessions focus on balanced nutrition in feed selection and the importance of precise feeding to prevent diseases and improve shrimp health [4]. Group 3: New Species Introduction - The introduction of a new shrimp variety, "Su Hu 1," is expected to enhance growth rates and yield, with characteristics that favor meat production over claw development [6]. - The use of bio-feed made from agricultural by-products and beneficial bacteria is being implemented to improve shrimp health and reduce fat-related diseases [6]. Group 4: Market Strategy - Farmers are adopting off-season farming strategies to avoid price drops during peak harvest months, aiming to sell shrimp at significantly higher prices during off-peak periods [7]. - The price of shrimp can increase from approximately 17 yuan per kilogram in the fall to between 28 and 30 yuan during the Chinese New Year, representing a substantial income opportunity for farmers [7].
