中文摘要 | 本研往於1997年起在南灣海域珊瑚礁發,進行復育相關資料之建立,研究分幾方 面,一、南灣海域珊瑚幼苗的回流量;二、珊瑚幼株早期的成長及存活狀況;三、實驗室內 珊瑚幼株早期的成長及存活;四、無性方法繁衍珊瑚。 整體而言,新附苗珊瑚密度低,而且分佈極不均勻,種類也以孵育型幼苗佔優勢,若要 由天然幼苗的回流來恢復破壞珊瑚礁的舊觀,將耗時曠日。南灣海域珊瑚幼生在附苗後的存 活率非常低,在附苗後第十二月的累計存活率約為29.2%,但至第二年調查結束時的累計存 活率,則約為0.7%,而死亡的幼生中有65.7%的幼生已脫離附苗處,其他仍可判斷者則是由 於沈積物、藻類與其他生物影響而死。實驗室中餵養紅色管星珊瑚、存活、成長及繁殖下一 代均可行,但珊瑚成長緩慢,且照顧費時、費工,未必適合大規模進行。利用珊瑚無性繁殖 之原理,在半人工環境下中間育成,繼而野放為目的,目前已在軸孔珊瑚上有顯著成果可再 擴大至更多種類。珊瑚苗哺之設置,可做為自然界復育的珊瑚來源,目前軸孔珊瑚已有相當 數量,在進行野外放養的方法比較中。 |
英文摘要 | An ecological study to evaluate the necessity and feasibility of coral reef restoration in southern Taiwan has been executed since 1997. We approached the task from four aspects, i.e., the natural recruitment rates of corals in the area. the growth and survival of natural coral spats, the collection of coral larvae and culture of coral spats in the laboratory, and finally, the asexual means of coral propagation. Our results indicated that the natural rate of coral recruitment was low in southern Taiwan. The spatial distribution of coral settlement was very uneven. Moreover, the coral recruits were mostly limited to species that brood their larvae. Broadcasting corals, the dominating species of existing coral fauna, were underrepresented. The natural recovery would be slow if the above pattern persists. The survival rates of those settled were low. The accumulative survival rate was 29.2% after 12 months; it dropped to 0.7% after 24 months. The mortality of coral spats was caused by sedimentation, predation and overgrowth of other organisms. In the laboratory, we tried one species, i.e., Tubastrea aurea. Larvae were released by coral colonies. They could settle and grow on artifical substrate, although the growth rate was low. Culturing them for the purpose of restocking the natural populations may not be practical since intensive care is needed which renders large-scale operation expense. Asexual means, using coral fragments, can be applied to fast-growing species, e.g., branching Acropora, with success in small-scale test patches. Low cost and maintenance-free setup as well as a coral nursery to provide transplants are keys to success in the field. |
