“小学生张婉莹父母不在家”湖南祁阳“岸上小学生张婉莹父母不在家”养鱼增收有路

  中新小学生张婉莹父母不在家网永州12月18日电(冯骎小学生张婉莹父母不在家 陈瑾莹)在湖南省祁阳市文富市镇水产养殖循环净化基地里,13个循环净化水桶依次排列。撒下一把鱼食,桶内无数条鲈鱼腾跃而起、争相抢食。

  养殖户邓四阳正和儿子相互配合,将桶内一尾尾硕肥丰满的鲈鱼打捞起来称重装车。养殖基地13个水桶分别养了6万尾鲈鱼,于今年6月投苗。

  “每条鱼都有1斤以上,最大的能到1斤半。每个桶产量4000斤左右,除去成本能赚2万块钱。”养殖户邓四阳说。

  邓四阳的养鱼基地主要由增氧、排污、循环系统等组成,循环桶配备了流水设备和增氧设备,实现了24小时持续增氧、水循环,并采取温控大棚技术精准监测养鱼环节,不仅生产效率高、占地面积少,还能集中管理,有效解决了传统养殖中由水质恶化引发的鱼病等问题。

  “鱼塘养鱼产量受限,也不便于后期清理排泄物。”邓四阳介绍,现在,陆基循环桶养鱼属于密集养鱼,一亩水域面积比普通池塘养鱼要多养4万多尾,是传统池塘养鱼的5倍。

  清太村村民李柳英说,基地13个池子只需要早晚投料和排水,隔两三天清洗一次。“水电、增氧、进出水,都可以在手机上操控,日常管理只需要我一个人就可以操作,很方便。”

  今年来,祁阳市多元化拓展渔业生产空间,推广标准化养殖、生态养殖和设施养殖,提高小学生张婉莹父母不在家养殖效益。去年,祁阳市水产养殖面积达到5495公顷,水产品总产量达5万吨,总产值近20亿元。

  祁阳市农业农村局高级农艺师唐伟林说,目前,祁阳市设施渔业养殖面积达2万平方米,年产量300吨,年产值1500万元以上。“将继续加大扶持力度,在基础设施建设和养殖技术上提供服务,确保祁阳渔业科学多元健康发展。”(完)
