洱海生态调控旨在通过调节鱼类群落,促进水生植被和浮游动物恢复,推动湖泊内源污染治理和水质改善。当前洱海水生态系统仍处于脆弱转型阶段,外来小型鱼类泛滥及土著鱼类种群萎缩是主要问题。
中新网云南大理9月16日电 (李婧 施隽伟)每到秋季洱海生态调控期间,夜间湖面渔船点点、灯火错落,成为苍洱秋日的独特景致。云南大理市洱海管理局称,即日起,2026年洱海鱼类生态调控工作全面启动。
与一般渔业捕捞不同,洱海鱼类生态调控旨在通过科学治理,优化鱼类种群结构,恢复湖泊生态功能。生态调控的最终目标是通过调节鱼类群落,促进水生植被和浮游动物恢复,推动湖泊内源污染治理和水质改善。
统计表明,今年共有611艘渔船参与生态调控作业,严格实行“一船一证”管理,每艘作业渔船均配备持证渔民,全程规范化开展捕捞工作。
大理市洱海管理局副局长郑国辉介绍,湖面上渔灯,本是生态调控作业中灯光诱捕,不意竟形成梦幻般的特色景观。
当前洱海水质持续稳定向好,但水生态系统仍处于脆弱转型阶段。水域内西太公鱼、银鱼等外来小型鱼类泛滥,土著鱼类种群不断萎缩,同时大龄鲢鳙控藻能力减弱,鲤、鲫等底层鱼类扰动底泥,加剧内源污染,破坏水体生态平衡。开展科学化、规范化的鱼类生态调控,能够持续优化洱海鱼类群落结构、修复失衡水生态、稳定提升水质,同时带动渔民增收致富,有效推动生态价值向经济价值转化。
本次生态调控严格依据《中华人民共和国渔业法》《云南省大理白族自治州洱海保护管理条例》相关规定实施,紧扣水资源、水环境、水生态“三水统筹”治理要求,精准修复洱海生态系统,筑牢洱海生态安全屏障。
在官方安排下,今年洱海鱼类生态调控分阶段稳步推进。外来小型鱼类调控时段为9月15日至10月8日、11月20日至12月5日;鲤、鲫、鲢、鳙鱼调控时段为10月10日至10月30日,每日作业时间统一为19时至次日8时。作业全程严格限定网具规格、作业水域,在科学调控鱼类种群结构的同时,最大限度保护水生生物资源,保障洱海生态系统良性循环。
世代依洱海而生的渔民,是这片湖光夜色变迁最真切的见证者。今年50岁的夏国兆,是大理市满江街道夏家村的村民,今年,他们一家人也一同报名参与洱海生态调控捕捞作业。
“我每年都参加生态调控,一个晚上最多的时候能捕捞五六百斤鱼。希望通过生态调控,湖水越来越清,把洱海保护得越来越好,我们心里就高兴。”夏国兆说。
一盏盏渔灯,既是作业时的照明,也是守护这片湖的点点微光,映照出大理久久为功的生态守护之路。
