澎湖水族館龍蝦脫殼吸引遊客目光

　　（中央社記者許耀彬澎湖縣三十日電）在夏天觀光旺季遊客絡繹於途的澎湖水族館，近日飼養在展示缸裡的錦繡龍蝦竟然自行脫殼，整個過程都由工作人員記錄下來，由於龍蝦脫殼長大的過程，平時難得一見，雖然遊客因為淡季人數不多，但仍吸引眾人目光，並認為將有好運氣。

　　目前由南仁湖集團經營管理的澎湖水族館，一直是澎湖夏天觀光旺季時的遊客參觀據點，館中蒐藏澎湖沿近海的各類海洋生物，其中色彩鮮豔的龍蝦也是遊客欣賞海洋生物時必定欣賞的對象，近日雖是淡季且遊客不多，卻有難得機會欣賞到龍蝦脫殼成長的自然景象。

　　水族館人員說，這隻脫殼的錦繡龍蝦，已在水族館飼養多年，在去年也曾抱卵孵出數萬隻的小龍蝦寶寶，錦繡龍蝦是龍蝦屬中體型最大者，最大體長可達六十公分，通常體型為二十至三十五公分。龍蝦為甲殼類生物，多棲息於水深一至十公尺的珊瑚礁海域，以岩礁及礁斜面靜水處為多，並以小型動物為食，有時偶爾也可在河口附近水質較混濁泥底處發現。

　　他解說表示，在龍蝦的成長過程中，通常第一年會有十四至十七次脫殼，而在性成熟後，則每一年或二年才脫殼一次，每次脫殼，身體全長可增加至百分之十五左右，但脫殼次數及增加的體長，一般會隨著龍蝦的種類、水溫、攝食率及其他因子而有些所差異。

　　他又說，一般龍蝦在脫殼前會先進行水化作用，以促進身體變為柔軟並很少進食，通常會把舊殼中所含的幾丁質和蛋白質再次攝食吸收，利用等新殼形成時再和舊殼分開，對龍蝦脫殼而言，是一件極為艱辛也是危險的過程，因為缺乏硬殼保護，會有許多外來的掠食和傷害等危險。

　　王姓遊客興奮的表示，他首次見到龍蝦脫殼，相當得也很高興，因為在民俗中見到龍蝦脫殼會有好運氣，這次到澎湖遊覽，雖然因為淡季沒有很多遊客，但卻親眼看到龍蝦脫殼，希望能帶來好運。961030
