The average taxonomic distinctness Δ+ was the highest in the southern Yellow Sea and lowest in the central Yellow Sea; the spatial variations were largely caused by the different spatial distributions of species belonging to orders Perciformes, Pleuronectiformes, Clupeiformes and Scorpaeniformes, especially those of cartilaginous species.

在区域尺度上，分类多样性指数Δ，分类差异指数Δ+在黄海中、北部较高，南黄海较低；等级多样性指数Δ+为南黄海最高，中黄海最低，其区域尺度变化主要是由鲈形目、鲽形目、鲱形目和形目种类，特别是软骨鱼类的种类数的分布变化造成的。

Through the traditional physiological and biochemical method, together with the 16SrDNA sequence homology and phylogenetic analysis, the strains were identified. The result shows they belong to the genus photobacterium, but they differ from any species of this genus in some characteristic which suggests they might be new species, and their taxonomic placement needs more information on genes level.
