| Research Abstract |
We substantiated the NOAA series with enough information to support an ocean survey by research ship.
We also need to try to research when an where the fishing grounds witll shift and whether these stocksa are going to increase, etc. Accordingly we need to accumulate and analyze the data and information by the use of a quantitative echo sounder and the use of several ships at the same time in order to make the plankton's biomass clear. In this case it would be more effective if quantitative echo sounder information were standardized.
The other way to plan for the efficient use of stock and of fishing ground production, is to make very accurate recordsof the fishing and oceanic conditions of sardine, the Japanese common squid, etc. At the same time we would neet to, with the cooperation of national or private research institutions, continue with the systematization of collection, management, and reporting of the data of fishing and oceanic conditions.
