摘要(Abstract)：

【目的】研究探讨造礁石珊瑚自然海区断枝培育技术的条件和方法。【方法】在深圳大鹏新区大澳湾海区海底搭建海区断枝培育系统,并在系统上培育膨胀蔷薇珊瑚(Montiporaturgescens)、霜鹿角珊瑚(Acropora pruinosa)、盾形陀螺珊瑚(Turbinaria peltata)、十字牡丹珊瑚(Pavona decussata)和澄黄滨珊瑚(Porites lutea)等5种造礁石珊瑚的断枝(每种珊瑚100株),开展为期12个月的实验。【结果】5种珊瑚在深圳市大鹏新区大澳湾海域的断枝培育系统上培育12个月后,5种造礁石珊瑚断枝存活率分别为96%、93%、95%、85%和83%。珊瑚断枝生长指标测量结果显示,5种珊瑚中霜鹿角珊瑚生长速度最快,其断枝横向增长长度平均可达46.2mm;其次是膨胀蔷薇珊瑚,其断枝横向伸长长度平均可达38.2 mm;而澄黄滨珊瑚生长速度最慢,横向伸长长度都在24mm以下。【结论】在合适海区,使用海区石珊瑚断枝培育系统进行造礁石珊瑚培育,可改善其存活率和生长。
