Microbial ecological research and bio-control of rearing water for fish seedlings

绿色微藻（如Nannochloropsis oculata）被广泛用于水产养殖业的鱼类育苗，被称为“绿水”。在这项研究中，玫瑰杆菌分支的丰度是重点，因为已知一些菌株对鱼类致病菌产生抑制物质。在培养中，玫瑰杆菌分支（RCA）种类繁多，数量丰富。有趣的是，玫瑰杆菌分支和浮游植物的结合增强了RCA对一些鳗弧菌的杀伤作用。

Green microalgae such as Nannochloropsis oculata are widely used for fish seedlings in aquaculture industry as Green Water. In this study, the abundance of Roseobacter clade is being focused, as some strains are known to produce inhibitory substances against fish pathogenic bacteria. In N. oculata culture, Roseobacter clade (RCA) were various and came to be abundant. Interestingly, the combination of Roseobacter clade and phytoplankton reinforced the killing effect of RCA against some V. anguillarum.
