北国江畔筑起生态屏障 ——探访吉林珲春密江河大麻哈鱼国家级水产种质资源保护区 ■解放军报记者尉寅础李庆桐深秋时节，记者走进吉林珲春密江河大麻哈鱼国家级水产种质资源保护区。密江河畔清风徐徐，清冽河水漫过河床。明年开春，数十万尾大麻哈鱼苗将从这里放流入江，顺流奔向大海。工作人员介绍，保护区2007年设立，总面积66.1平方公里，是我国第一批国家级水产种质资源保护区之一。这里是国内为数不多保留原生河床地貌，同时承载大麻哈鱼、驼背大麻哈鱼、马苏大麻哈鱼三种大麻哈鱼洄游产卵的水域。大麻哈鱼生于江河、长于海洋，是典型的溯河洄游性鱼类。幼鱼顺流入海，在海中发育成熟后，逆流千里返回故地，秋季在河床石头间产卵，是串联海洋、河流与山林生态系统的重要物种。不同于大熊猫、东北虎等国家一级保护动物，大麻哈鱼属于经济鱼类，沿岸不少渔民以捕捞它们为生。为了保护它们，在图们江下游的防川村，传统渔场保留至今。每年洄游季，渔民捕捞的成熟种鱼由渔政部门统一收购，转运至密江乡的良种场暂养催产。近年来，珲春市密江乡扎实推进流域生态保护，严格落实河长制、林长制，建立乡、村两级生态保护体系。渔政、公安、检察等部门组织常态化联合巡护，严厉打击非法捕捞行为，增设生态保护标识标牌，持续实施水生生物增殖放流。自然条件下，大麻哈鱼存活率偏低，科学的人工增殖放流，是恢复种群资源的重要手段。走进密江河畔的延边马苏大麻哈水产良种场，记者在孵化器中看到一粒粒橘红色的鱼卵。据工作人员介绍，孵化器可以模拟自然条件下的温度和水流，鱼卵孵化率达80%以上。目前，全国各地大麻哈鱼放流站普遍在每年10月到11月初的洄游季采捕种鱼，经先进孵化系统人工繁育，来年开春放流入海。截至2026年，吉林省在图们江流域累计放流大麻哈鱼476万尾；仅2026年春季，就在密江河保护区投放大麻哈鱼52万尾、马苏大麻哈鱼8万尾。守护种质资源，兼顾富民发展。当地依托密江河保护区独特的生态资源，积极开展生态科普研学活动，向大众普及大麻哈鱼洄游知识，传播生物多样性保护理念；在严守生态底线的前提下，统筹种质资源保护与乡村绿色产业发展，探索生态保护与地方经济协调发展之路。一江碧水奔图们，万尾游鱼赴故乡。密江河里年年归来的大麻哈鱼，既是当地持续推进水生生物保护、筑牢生态屏障的生动实践，也是我国生物多样性保护的鲜活注脚。
