6日,“6·6八闽放鱼日”大型水生生物增殖放流活动在全省联动举行。省人大常委会副主任黄琪玉,副省长李德金以及省直有关单位、福州市的领导在福州闽江公园望龙园百花台景区出席主会场活动。
此次放流活动全省布设分会场11个,将投放大黄鱼、真鲷、黑鲷、长毛对虾、石斑鱼、棘胸蛙等物种累计超过4亿尾(粒)。其中,主会场放流日本鳗鲡3000尾(每尾约500克),鲢、鳙40万尾。这些水生生物的投放将对维护水域生物多样性,改善渔业资源和提升生态环境质量起到重要的促进作用。据悉,2019年我省将在全省范围内放流水生生物超过40亿尾(粒),全面完成“十三五”水生生物增殖放流总目标任务。
近年来,我省增殖放流效果初步显现。鲢、鳙鱼类增殖放流有效消减氮磷,改善生态环境,抑制水华发生,对于内陆水域有明显的生态效益:放流鲢、鳙每年直接从水体中抽取氮超过150吨,磷超过30吨;若以污水处理场每去除1kg氮的成本46元、去除1kg磷成本230元计算,折合增殖放流产生生态效益每年超过1500万元,“十二五”以来产生生态效益超过1亿元。(记者 张静雯)
