青岛市民组团挖"海知了" 专家:再吃又要灭绝了

(原标题:青岛市民组团挖“海知了”,专家:可以吃,但再吃又要灭绝了)
昨天我们《今日》报道了石老人海水浴场附近,市民组团挖“海知了”的事。在昨天节目中,我们采访的水产工程师介绍,这种“海知了”市民可以放心吃。
可是节目播出后,不少观众提出了疑问:
虽然说可以吃,但这样任由市民去挖去吃,真的合适吗?如此“挖掘”是否会破坏海滩的风貌?又会不会让“海知了”越来越少,甚至破坏生态环境?
看到了大家的留言,我们也十分重视!今天也再次对此事进行了核实!
昨天的节目播出后,不少网友在我们的微信平台上留言,希望不要再扩散有关“海知了”的消息,也不要鼓励大家都去挖。也有网友称这种“海知了”并非蝉虾,而是一种叫做“解放眉足蟹”的生物。
青岛市民组团挖海知了 专家:再吃又要灭绝了
“解放眉足蟹,不是蝉虾。是刚恢复的物种,七几年在青岛地域性灭绝,现在刚恢复四年,四年前开始出现,它们对于沙滩有很好的维护作用,这样报道之后,它们又要面临地域性灭绝了。”——网友
网友们说的到底是否真实情况?今天上午记者再次来到石老人海滩,发现三五成群的市民比昨天更多了,他们正在海滩上寻找“海知了”的踪迹,大部分都拿着大铁锨和水桶,一大早的收获还不少。
大多数市民都表示是第一次见到这种生物,但是对于是否需要保护?大家确实没有很明确的概念……
这种生物到底是否像网友所说,四年前重新出现在青岛海域、需要大家的保护?
带着问题,记者咨询了黄海水产研究所的专家周丽青。
专家:解放眉足蟹 是珍贵的海洋生物
经专家鉴定,“海知了”的学名确实是“解放眉足蟹”,在山东,最先发现它的地方是烟台,后来是日照,最近才在青岛的海域上发现。
“我在日照看到的是整个鳌是黑色的,这边的旁边发白,这是雌性的,像是生殖器还有游泳足,都是雌性所特有的。”周丽青说。
连续挖掘 导致资源下降
专家介绍,这种解放眉足蟹实际上存活的范围较窄,并对其栖息的沙滩有重要的生态意义,是一种介于虾和蟹之间的珍贵海洋生物。
“一般都是位于低潮区的细沙这样的地方,生存比较好一些,它对低潮区的细沙起到了疏松清洁的作用,由于它的营养价值比较好,村民对它就有大量的采挖,连续多年这种地毯式挖掘,使得解放眉足蟹的资源量就下降了很多,像在日照下降了70%多。”
低龄蟹遇“灭种”危机
解放眉足蟹与普通的对虾、梭子蟹不同,成熟期至少要两年,被端上餐桌的解放眉足蟹都是在3岁以上,因此解放眉足蟹资源一旦被破坏,很难修复!
“像低龄的1到2龄的解放眉足蟹也遭到了很大的伤害,使得整个种群面临灭绝的危险,而且它对生态环境是有修复作用的,所以尽管美味,还是建议大家,不要去采挖。”周丽青说。
《今日》有话说:
让“海知了”长住岛城,善莫大焉!
一件小事引起了这么大的关注,是我们在播出这条新闻之前始料不及的,这说明市民们的生态环保意识越来越强,大家不愿意看到我们身边的环境受到一丝一毫的损害。从前几年销声匿迹,到这几年“重现江湖”,“海知了”的回归是大自然的馈赠,也是对岛城海洋资源修复工作的充分肯定。
专家说,“海知了”就像泥土中的蚯蚓,对疏松和清洁沙滩发挥着不小的作用,因此,我们要善待这个小生命,让它在青岛安家落户、繁衍生息,并成为岛城海滩一道新的风景线。
任何资源都不是取之不尽,用之不竭的,如果我们不加约束地滥挖滥捕,“海知了”很可能就会再次从青岛人的视线中消失。青岛人都有赶海的传统,但是经过了生态破坏的教训,我们在赶海的时候更要尊重大海的规则,对自然保有一颗敬畏之心。
因此,出于生态环境和物种保护的需要,我们还是不建议大家去采挖“海知了”,而是让它留在沙滩,与我们共享这片蓝天和大海!

市民们的生态环保意识越来越强,大家不愿意看到我们身边的环境受到一丝一毫的损害,但是在吃得问题上没得商量。

专家要宣传不能吃!不然能吃的都会被吃灭绝!
不过现在关键不是吃的问题,现在是还可以卖钱的问题。
