Offshore Surface 414 East China Sea waters

Note; The offshore surface areas have many physically fluid factors such as ocean current or seasonal changes, which may effect on the spawning grounds or distribution areas of certain organisms. Therefore, it is difficult to fix certain area as EBSAs of offshore surface spatially. In addition, available data for analysis are very limited. Therefore, the EBSAs of offshore surface shows the probabilistic distribution of important area as a result of mechanical analysis using best available data at the time, so that there are problems such as that some places considered to be consecutive from the ecological features are divided. Further analysis will be required to improve when the data became available in the future, and it is necessary to review the analysis method.

Basic Information A separate window opensReferences

Area (km2) 124147

Reason(s) for selection A separate window opensCriteria

Selected due to high levels on the criteria 2, 6. And selected by the MARXAN software.

Characteristics A separate window opensReferences

Located at the continental shelf and slope on the mainland China side, these waters are supplied with large volumes of materials form the continent, resulting in very large quantities of organisms. They are spawning and nursery waters for numerous species of pelagic fish (yellowtail, saurel, mackerel and others) and for winter schools of Japanese flying squid, which migrate north along the warm Tsushima Current and the northern Pacific Kuroshio Current.
