• Construction of giant jellyfish monitoring system and Information service

• Giant jellyfish in 2006– The migration speed is a little slower than 2005. – Is it fewer than 2005?

• The change is large– Day by day, Area, Fishing method

– Size is small (The ratio of small size is large)– Kuroshio area is not distribution area now.– Following group – Damage

• Extension of working time, Deteriorates of fish freshness.

• Future study– Offshore monitoring and following group monitoring.– Forecasting
