鲍鱼也要“人与禽CORPORATION外网走南闯北”越冬避暑?揭秘小鲍鱼的“候鸟式”养殖

“人与禽CORPORATION外网”鲍鱼也要“人与禽CORPORATION外网走南闯北”越冬避暑?揭秘小鲍鱼的“候鸟式”养殖

  山东人与禽CORPORATION外网荣成是我国主要的鲍鱼养殖人与禽CORPORATION外网基地,由于鲍鱼在养殖过程中对海域的水温、水质要求苛刻,为了让鲍鱼安全“越冬”,山东荣成和福建连江多年来持续采用鲍鱼“南北转场”“冬夏对调”的养殖合作模式。每年11月份,山东荣成的鲍鱼会陆续运往福建连江,到了来年5月再回到荣成养殖。

  鲍鱼陆续抵达福建连江之后怎么安家?跟记者一起揭秘鲍鱼的南下“越冬”之旅。

  总台记者 万存灵:在深远海鲍鱼养殖平台“福鲍一号”上,养殖户们正在将一些体型较大的鲍鱼放入养殖笼中。海面上,一笼笼鲍鱼正乘坐着小船运往平台。3天前,从山东荣成出发的鲍鱼抵达这里。养殖户利用船上的吊机卸货,可以一次同时将100个养殖笼转移到一旁的小型运输船上。

  随后,养殖户们会将鲍鱼运往附近的养殖渔排进行挂笼立体放养,让它们休整一会儿。今天,有些个头大的鲍鱼被选为“优等生”,放到“福鲍一号”的家里继续喂养,剩下的小鲍鱼则会继续留在养殖渔排上喂养。

  “福鲍一号”养殖平台 助力“智慧渔业”

  “福鲍一号”上有15000个鲍鱼养殖箱,鲍鱼们会被放到水深8米的位置,这也是最适宜它们生长的深度。相较于传统养殖渔排,这里海水交换量大,水温更加稳定,可以大大提高鲍鱼的成活率,也能增加鲍鱼的重量和产量。相比传统养殖,“福鲍一号”养殖平台还可以节省60%的人工成本,实现了从“汗水渔业”向“智慧渔业”的转变。

  “福鲍一号”养殖平台的“黑科技”

  在“福鲍一号”上生活的鲍鱼们,吃饭也有“黑科技”加持。工作人员只需要按下控制按钮,鲍鱼们就可以乘坐“海底电梯”缓缓来到水上平台,再打开笼盖就可以轻松给鲍鱼投食了。按照传统的养殖方式,工人在投喂鲍鱼时,需要靠人力把笼子从水下费力地提升到海面上,凭经验投喂食物,然后再把养殖笼投放进海里。

  在这种精心打造的居住环境里生活的鲍鱼,个头更大,品质也很好。例如绿盘鲍品种的大小差不多是人手的大小,养殖户估算它的重量有250克到300克。

  在“福鲍一号”上生长的鲍鱼,基本都是长到250克以上,也就是俗话说的“两头鲍”再出售,越大个的鲍鱼价格也就越高。“两头鲍”意味着一斤里,有两只鲍鱼,每只重约250克。“五头鲍”,是一斤里有五只鲍鱼,每只重约100克。

  “候鸟式”养殖 夏“避暑”冬“避寒”

  在鲍鱼养殖过程中,鲍鱼对海域的水温、水质要求十分苛刻。为了让鲍鱼过上“舒坦日子”,山东荣成和福建连江多年来持续采用鲍鱼“南北转场”“冬夏对调”的养殖模式。在11月份的时候,鲍鱼会来福建“越冬”,来年四五月份的时候,它们再去荣成“避暑”。

  这种“候鸟式”养殖模式有效避免了海水温度过高或过低对鲍鱼的影响,大大提高了养殖收益。连江县去年鲍鱼产量达到了5.66万吨,占全国总量的三分之一左右,产值超47亿元。今天这批小鲍鱼明年5月份又要去荣成“避暑”了,期待它们在这期间长得越来越肥。
