Offshore Surface 418 Surface waters of Musashi Bank

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.

While these waters can be considered to have an environment similar to that of the waters of Nos. 415, 416, and 417, they have been chosen as separate waters for this analysis due to a lack of data and for other reasons. The Musashi Bank is a feeding ground for flounder, sand eel, herring and others, and Okhotsk atka mackerel, cod, and North Pacifica giant octopus live here as well. It also is a nursery ground for Alaska pollock fry that settle here beginning in the summer, and it is a good fishing ground as well (Sakurai, personal communication). These waters also are an important feeding ground for migratory birds that breed on Teuri, Yagishiri, Rebun and other islands.

(Note: Same as No. 402)
