Hong Kong Jellyfish Project's Journal

There are around 20 species of freshwater jellyfish found across the world. One of the most invasive species is Craspedacusta sowerbii, thought to originate in the Yangtze river basin in China. The first sighting in the Hong Kong literature is from the 1940’s! This species has more recently been sighted around Hong Kong and observed in reservoirs. C. sowerbii appearances are unpredictable, so as you are hiking around HK’s many reservoirs, ponds and streams, look for freshwater jellies and let us know if you see them.

現時世界上發現到的淡水水母（又稱「桃花水母」）有約20種，其中Craspedacusta sowerbii是一種入侵物種，一般認為牠們原生於長江流域。在香港，記載有人目擊到牠們的文獻更早於1940年代！最近在香港四處也有人目擊這種水母，也有人在水庫裡看到牠們。牠們的出現很難預測，因此當你在香港不同水庫、水塘和溪流附近遠足時，記得留意有沒有桃花水母出沒，發現到的話，請告訴我們。
