大蛇灣

簡介

📍 概況：位於糧船灣洲大蛇頂山腳，西面對住滘西洲，屬避風內灣。 🤿 環境：平均水深 5m 內，最深約 10m；糧船灣洲擋住東面及南面風浪，水面大多平靜，較深處為平坦沙泥底。 🐠 生態：漁護署珊瑚普查顯示珊瑚覆蓋率可超過 60%，淺水有多種硬珊瑚、大型腦珊瑚及菊花珊瑚；常見勒氏笛鯛、玻璃魚、鰕虎、隆頭魚及克氏海葵魚，幸運可見黑帶前角魨、粒突箱魨及管海馬。 漁護署 2025 年珊瑚礁普查石珊瑚覆蓋率：約 48%。 ⚠️ 須知：夏季遊艇及滑水船多，水面繁忙兼會影響能見度，升水時必須施放 SMB。

📍 Overview: At the foot of Tai She Teng on High Island, facing Kau Sai Chau to the west; a sheltered inner bay. 🤿 Conditions: Average depth within 5m, maximum about 10m. High Island blocks wind from the east and south, so the water is mostly calm; flat sandy-silty bottom in deeper parts. 🐠 Ecology: AFCD Reef Check data shows coral cover can exceed 60%, with diverse hard corals, large brain corals and daisy corals in the shallows. Russell's snapper, sweepers, gobies, wrasses and Clark's anemonefish are common; lucky divers may see blackbar filefish, yellow boxfish and spotted seahorses. AFCD Reef Check 2025 hard coral cover: about 48%. ⚠️ Note: Busy with yachts and wakeboarding boats in summer, which can also reduce visibility. Always deploy an SMB on ascent.
