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，许多美丽的珊瑚生活在金枪鱼笼的绳索上。这表明将在这一地区进行适当的水产养殖活动。这种水产养殖与珊瑚的共存在世界上是非常罕见的。在这项研究中，我们将重点放在海洋细菌和珊瑚粘液的生态功能上，作为了解生态系统奇妙平衡的第一步。黏液采集自金枪鱼笼绳上的优势种Acropora sp.。“黏液+海水”样品的细菌丰度在培养10 h时增加，而海水样品（对照）的细菌丰度较低且保持不变。细菌组成在“黏液+海水”样品中变化剧烈，而在海水样品中没有变化。

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.
