蠔涌生態🐟矛盾，其獨有生境因風水而持續發展，外來魚令原生物種面對被競爭等的威脅，人為護養能否帶來契機？反思人與大自然彼此依存的關係。＃香港生態價值河流＃香港遊＃環保＃香港生物多樣性＃河流考察＃

Ho Chung is an ecological contradiction. Its unique river habitat is derived from the concept of Chinese Feng Shui and continues to develop. The introduction of exotic fish has exposed native species to threats of predation and competition for resources. Can artificial conservation bring opportunities? Thus reflecting on the interdependent relationship between man and nature. #香港ecological value rivers #hongkong tour #environmental protection #hongkong biodiversity #river research# 提起蠔涌，往往想起蠔涌村的手繪壁畫和村口的車公廟。蠔涌這條平靜的小溪卻因被村民視為風水命脈而面對著兩極的生態矛盾：河流生境得到村民持續守護，當你會看到溪流中的就米飯知道村民對河魚的持續餵養；此外，村民引入風水魚或寵物魚，這些外來魚會令原生物種受威脅，被捕食或競爭資源，例如青劍魚Xiphophorus hellerii.var、麥氏擬平吸鰍Pseudogastromyzon myersi、溪吻鰕虎魚Rhinogobius duospilus、舌鰕虎魚等。你會發現神魚錦鯉無處不在，鯪魚、非洲鯽、巴西龜甚至鯇魚，都是村民放生對象，河涌的生機在哪？ 「涌」是指河道流出海的地方，海水的倒灌形成涌口鹹淡水交集的生境。 本集我們會從蠔涌的源頭出發，在山谷尋找極淡水生境，到中游了解放養魚對生境的影響，及至描述涌口鹹淡水生境情況，了解這條短小、坡度較小的涌溪從淡水流域到鹹淡水間的微妙變化，反思人與大自然的關係，可說人的信念養活了蠔涌的生命，蠔涌又似乎保守村內代代的人，彼此依存本乎自然之道，你說對嗎？ 歡迎訂閱@Raymond2021 When talking about Ho Chung, people often think of the hand-painted murals in Ho Chung Village and the Che Kung Temple at the entrance of the village. However, this peaceful stream in Hoy Chung is faced with two extreme ecological contradictions because it is regarded as the lifeblood of Feng Shui by the villagers: the river habitat is continuously protected by the villagers. When you see the rice in the stream, you know that the villagers continue to feed the river fish; In addition, villagers introduced Feng Shui fish or pet fish. These exotic fish will threaten native species, be preyed on or compete for resources, such as swordfish Xiphophorus hellerii.var, Pseudogastromyzon myersi, and goby fish. Rhinogobius duospilus, tongue goby, etc. You will find that sacred fish, koi, are everywhere. Dace, African crucian carp, Brazilian tortoise and even grass carp are all targeted for release by villagers. Where is the vitality of the river? "Swell" refers to the place where a river flows out of the sea. The intrusion of sea water creates a habitat where salty and fresh water meet at the mouth of the swell. In this episode, we will start from the source of Hoy Chung, search for ultra-fresh water habitats in the valley, go to the middle reaches to understand the impact of free fish farming on habitats, and finally describe the salty water habitat conditions at the mouth of Chung Kwai to understand the origin of this short, shallow Yong Creek. The subtle changes from fresh water basin to salt water reflect the relationship between man and nature. It can be said that people's beliefs feed the life of Hoy Chung, and Hoy Chung seems to protect the people of the village from generation to generation. Interdependence is the way of nature.
