挪威泛滥的帝王蟹:专家呼吁引进天敌 但就是找不到

2017-06-11 15:43:25   今日头条

帝王蟹在近些年来深受国内一些富裕家庭喜爱,肉多鲜嫩,一只足够一个人吃饱,就是太贵了,酒店里正常的一只均价超3000。但这也要看地方,有些地方帝王蟹还是让人头疼的物种。

比如挪威(图为挪威渔民捕捉帝王蟹),一开始挪威是没有帝王蟹的,据说是俄罗斯的科学家带了7只过来做实验,后因这里的水质水温特别适合帝王蟹繁殖,帝王蟹数量便开始膨胀起来了。

根据2014年的数据统计,挪威帝王蟹数量超过2千万只,而挪威目前的人口也就500万左右,刚开始的时候还能消化下。

问题是目前挪威人已经吃腻了帝王蟹,帝王蟹已经威胁了挪威海域的生态环境了,为了减少数量,挪威政府鼓励挪威人民一年四季可以任意捕捞帝王蟹。

图为挪威居民夏季捕捞帝王蟹,纯粹是好玩,但这也捕捞不了多少只。

一些挪威相关专家呼吁可以采用引进天敌的方式来对抗帝王蟹,在尝试一些海洋生物后,发现效果一般,大家觉得这挪威帝王蟹的天敌应该是什么呢。
