大閘蟹再上榜! 美國馬里蘭州發佈螃蟹通緝令!

Maryland officials are asking anyone out on the water to keep an eye out for an invasive species known as the Chinese Mitten Crab.

美國馬裏蘭州的官員們要求人們在下水時注意一種名爲“大閘蟹”的入侵物種。

The animal first made an appearance in the US in the 1980s and has come and gone since then. It has also been spotted in the Cheasapeake Bay over the years.

大閘蟹於上世紀80年代首次在美國出現，此後在美國時有時無，近年來又有人在切薩皮克灣發現了這種動物。

While the population has gone down substantially, scientists are now raising concerns there may still be some lurking in the waters.

雖然大閘蟹的數量已經大幅下降，但科學家們現在開始擔心，可能仍有一些潛藏在水裏。

The crab is known to disrupt ecosystems and eat fish eggs, proving to be a threat to other crab species.

這種螃蟹會破壞生態系統，吃掉魚卵，對其它螃蟹種類也構成威脅。

With its distinct claws that appear to be furry or covered in algae and a light brown or olive green body, they can grow up to 10 cm wide. The animals can also be found in both freshwater and saltwater.

大閘蟹的爪上有毛或藻類覆蓋，身軀呈現淺褐色或茶青色，成年大閘蟹的個頭能達10釐米寬。它們在淡水或海水中都可能出沒。

Anyone who spots one should not throw it back into the water, but put it on ice or freeze it, take photos and note the location where it was found, officials say. All sightings should be submitted to the Mitten Crab website.

官員們表示，人們看見大閘蟹時不應該將其扔回水中，而要將其置於冰上冷凍，拍照，並註明發現它的地點。所有相關信息都應該提交至“大閘蟹網”。
