屏東海生館引進「人工海鹽測試缸」,希望能研究出適合珊瑚穩定居住環境。(屏東海生館提供)
被譽為海中熱帶雨林的珊瑚礁生態,種類繁多,繽紛美麗卻脆弱,尤其在人工畜養環境培育及照護是門艱深學問及工程,屏東海生館近年引進「人工海鹽測試缸」,測試人工海水蓄養珊瑚成效,希望能給珊瑚更友善適合環境。珊瑚生長在陽光充足、水溫適宜、水質清澈、具水流的岩礁海岸,若感覺到水溫變化、混沙淤積就會白化,甚至死亡,因此海水比例、水質檢測、光源、水流強度等要嚴謹控制。

屏東海生館引進「人工海鹽測試缸」,希望能研究出適合珊瑚穩定居住環境。(屏東海生館提供)
被譽為海中熱帶雨林的珊瑚礁生態,種類繁多,繽紛美麗卻脆弱,尤其在人工畜養環境培育及照護是門艱深學問及工程,屏東海生館近年引進「人工海鹽測試缸」,測試人工海水蓄養珊瑚成效,希望能給珊瑚更友善適合環境。珊瑚生長在陽光充足、水溫適宜、水質清澈、具水流的岩礁海岸,若感覺到水溫變化、混沙淤積就會白化,甚至死亡,因此海水比例、水質檢測、光源、水流強度等要嚴謹控制。
if (typeof (ONEAD) !== undefined) { ONEAD.cmd = ONEAD.cmd || []; ONEAD.cmd.push(function () { ONEAD_slot(div-inread-ad, inread); }); }
珊瑚飼育組長吳政霖表示,以往直接引用海水入缸,珊瑚生長環境不穩定,因海水經颱風、雨水產生變化會造成珊瑚顏色變淡、珊瑚蟲萎縮等,傳遞死亡警訊,去年至高雄、台南等水族館交流決定使用人工海鹽測試缸,觀察人工海水飼養成效及找出最佳鹽分比例。他說,不同人工光源及水流也會影響珊瑚形態,展示缸使用傳統人工光源鹵素燈耗能高且效率差,因此測試缸一併試驗以LED燈具,觀察光譜是否符合珊瑚生長所需,半年來狀況穩定,不排除未來也將前場更換為省電LED燈。另外,一缸多用海鹽缸還能觀察敏感珊瑚對水流適應程度,珊瑚形體因應潮差、海流變化呈現枝幹粗細、長短等差異,幫助館內決定展示缸擺設位置。(中國時報),
