Abstract
In 1996, Japanese Fisheries Agency started management of fisheries resource by TAC (Total allowable catch). The management of the fisheries resource is an important issue. In this research, it was tried to elucidate the change of the fish resource by using the satellite data. The study fish is a sardine. Sardine resource around Japan repeats a big increasing and decreasing. Sardines catch volume increased rapidly in 80's, and decreased sharply in 90's. The change trend of an oceanic environment of the Touhoku sea area was presumed according to this multi satellite data at the period. The trend of the water temperature presumed from the satellite rose. On the other hand, the trend of Chlorophyll-a presumed from the satellite was descending. The data of the water temperature and Chlorophyll-a presumed the satellite was compared with the data of the sardine resource. As a result, a positive correlation was confirmed between Chlorophyll-a and the sardine resource of Oyashio water and perturbed water. On the other hand, a negative correlation was confirmed between the water temperature and the sardine resource.
