The coral reefs in Kenting are spawning a month earlier than usual. During underwater observations last week, Tsai Yung-chun, president of the Taiwan Underwater Photography Association, discovered that coral reefs near pipes from which the Third Nuclear Power Plant releases hot wastewater were already spawning. The resplendent scene of spawning corals was no less remarkable than Kenting’s lively Spring Scream music festival that was underway on shore.

In the depths of undersea darkness, various species of corals, including Favites chinensis, Galaxea fascicularis, Leptoria phrygia and Favia laxa, all began spawning in splendid, vibrant colors on Friday last week. The vast number of round eggs floating around was as gorgeous as the starlit sky.

Corals in Kenting typically spawn at the end of April and the beginning of May, only occasionally spawning earlier or later. On April 4, Tsai and a group of people went underwater to make observations, photographing the spawning coral reefs. Based on observations made over the past four years, he says that there is usually an explosive coral spawning during the third and four months of the lunar calendar, but that this year’s coral spawning occurring as early as the second lunar month was quite a rarity.

Fan Tung-yung, a biologist at the National Museum of Marine Biology and Aquarium, says that the effect of hot wastewater being discharged from the Third Nuclear Power Plant has caused the water in the area to be warmer by around one degree, which could be causing the corals to spawn early. As to whether it is a full-scale phenomenon still requires more observation, Fan says.

墾丁珊瑚今年提早一個月出現集體產卵現象,中華民國水中攝影協會理事長蔡永春上週下水觀察,發現核三廠出水口附近的珊瑚開始產卵,海底璀璨繽紛盛況不輸給陸上熱鬧的墾丁音樂季「春天吶喊」。

墾丁海域的菊珊瑚、叢生棘杯珊瑚、密集迷紋珊瑚、疏菊珊瑚等,從上週五開始漂出渾圓飽滿的珊瑚卵,五彩繽紛的色澤,在幽暗海面下,就像星空一樣美麗。

墾丁海域的珊瑚習慣在四月底五月初產卵,偶爾出現提早或延後的情況,蔡永春等人最近密集下水觀察,四月四日拍攝到珊瑚集體產卵畫面。蔡永春說,根據最近四年的觀察,農曆三月及四月是墾丁珊瑚產卵大爆發期,今年大幅提前在農曆二月集體產卵,格外罕見。

海生館珊瑚專家樊同雲指出,核三廠溫排水效應,使得當地海水溫度略高於其他海域一度左右,後壁湖一帶的珊瑚確實可能出現提早產卵現象,是否為全面性的現象,還有待觀察。
