密云水库禁渔 581吨鱼苗入库 北京包括官厅水库在内的41处水库湖泊全部进入禁渔期
本报讯昨日零时起,密云水库正式进入今年的禁渔期同日,密云水库增殖放流工作启动,预计在未来半个月内将有581吨净水鱼苗分批投入密云水库根据消息显示,与密云水库同样,包括官厅水库等在内的41处水库湖泊都进入禁渔期,全面禁止渔业捕捞作业
昨日,在密云水库三号坝,黑色的鸬鹚,灰色的苍鹭,白色的西伯利亚银鸥等鸟类在蓝天碧水间自由飞翔着,似乎在等待着什么9时30分许,几辆满载着鱼苗的运输车驶进,停靠工作人员先是选取了一小桶鱼苗进行打样,称重,我们在选购鱼苗时,要求每尾都在2到4两左右,抽取部分鱼苗打样,称重,数尾数,再核算出每尾的重量,检验是否符合质量要求密云区农业服务中心副主任郑伯秋表示之后,又有工作人员将消毒剂撒入运输车厢,对鱼苗进行消毒之后,鱼苗就被分批倒入浑身满是漏眼的大型称重簸箕内,由吊车送至水库边的四方的围池中,在这个过程中,水分被沥出,总重量就能显示在后台电脑中郑伯秋解释道只见活着的一尾尾鱼苗入水后,欢快地四散游去,零星死去的鱼立马被捞出
这时候,等候多时的飞鸟们显得激动起来,纷纷前来觅食,一时间禽鸟翻飞,鱼儿畅游场面蔚为壮观。
据密云水库管理处相关负责人介绍,今年是在密云水库连续开展鱼苗投放工作的第20个年头,预计在未来的15天,通过开展增殖放流活动,将有581吨净水鱼苗分批投入密云水库主要品种为鲢鱼,鳙鱼,鲂鱼等,是为了发挥这些滤食性鱼类的净水作用,消除水体富营养化,净化饮用水水源地水体,改善水生态环境,实现‘以鱼养水,以鱼净水’的目的,像以藻类和浮游生物为食的花鲢,白鲢,每增长1公斤体重就能‘消灭’40公斤到50公斤蓝藻同时,还能促进密云水库生物多样性的发展相关负责人表示
根据消息显示,进入禁渔期,北京市密云水库管理处持续加强与相关部门的合作,对库区实行全封闭式管理,禁止捕鱼船只,无关人员进入库区,协同执法力量,查处非法捕捞行为同时,还将对水面岸坡加大巡视打捞力度继续加强水生态监测与数据分析,做好库区水面保洁,封闭管理设施维护的全过程监管和精细化管理工作,完善生物多样性保护数据的收集整理,夯实密云水库生物家底统计工作,全力保障密云水库水环境与水生态安全
