The first step towards coexistence and co-prosperity of bluefin tuna farm and natural coral

在近畿大学奄美实验站的金枪鱼笼的绳索上生活着许多美丽的珊瑚。这表明将在该地区开展适当的水产养殖活动。水产养殖和珊瑚的这种共存在世界上是非常罕见的。在这项研究中，我们专注于海洋细菌和珊瑚粘液的生态功能，作为了解生态系统奇妙平衡的第一步。采集的粘液来源于金枪鱼笼绳索上的优势种鹿角珊瑚。细菌丰度在“粘液+海水”样品在10小时孵育增加，而在海水样品（对照）是较低的和恒定的。“粘液+海水”样本中的细菌组成发生了巨大变化，但海水样本中的细菌组成没有发生变化。

Many beautiful corals are living on the ropes of tuna cages in Amami Experimental Station of Kinki University. This suggests that the appropriate aquaculture activities would be done in this area. Such co-existence between aquaculture and coral is very rare in the world. In this study, we focused on the ecological functions of marine bacteria and coral mucus as the first step to understand the wonderful balance of the ecosystem. The mucus was collected from Acropora sp. which was a dominant species on ropes of the tuna cages. Bacterial abundance in the “mucus+seawater” sample during 10-h-incubation increased, while that in the seawater sample (control) was lower and constant. Bacterial composition changed drastically in the “mucus+seawater “ sample, but not in the seawater sample.
