Abstract

The giant jellyfish, Nemopilema nomurai, is an endemic species found in Northeast Asian waters and their population structures, such as size and genetics, and their environmental characteristics were investigated. N. nomurai was obtained from the Yellow and Northern East China Seas during the summers of 2006, 2007, and 2009. In the northern Yellow Sea, small-sized jellyfish were found to be dominant and towards the southern seas, the size of the jellyfish increased. In the northern East China Sea, only one mode of jellyfish was found in May, and the number of modes increased up-to five in July. However, at the center of the Yellow Sea, one or two modes were found in July, 2007. Thus, different jellyfish populations were present in the northern East China Sea and the Yellow Sea. However, based on first appearance and a cohort analysis using the bell diameter, the jellyfish population in the northern Yellow Sea might be recognized as a distinct group that differed from those found in the northern East China Sea. Furthermore, mitochondrial DNA sequences (cytochrome c oxidase subunit I) of N. nomurai were, determined and compared with genetic structures obtained from jellyfish in the Yellow Sea. The genetic diversity of N. nomurai was highest in the regions around the northern East China Sea and at the center of the Yellow Sea and was the lowest around the northern Yellow Sea. Thus, N. nomurai populations in the Yellow Sea and northern East China Sea might be different concerning their seeding places.
