1. Integrated Coastal Management
ICM ( Integrated Coastal Management) was described inAgenda 21 that was adopted in Rio Summit 1992 toachieve continuous development. Also in Japan, it ispositioned as Basic Act on Ocean Policy adopted in 2007
through The 5th Comprehensive National Development
Plan (cabinet approval in 1998) and Guideline forIntegrated Coastal Management Plan (National Land
Agency, 2000).
By implementing ICM, it considers the expanse ofplace and business, and it is thought that custom-madeenvironment preservation / reclamation is possible basedon participation of various elated persons. NILIM has
been trying various menus of ICM as an ecologicalcorrectness means.
2. Abode of spiny goby search project
In ICM, a goal of action which should be easy tounderstand for related people is needed. With that, aresearch was carried out and that was focused on spinygoby that is typical fish in Tokyo bay.
The research had been carried out between July andSeptember in 2012. Special research sheets, rulers formeasuring spiny goby were created, and it was reported
by fax. http://www.meic.go.jp/edohaze ） 。 From thebeginning, the general outline and recruitment for theresearch placed in fishing news papers / magazines and so
on with the cooperation of the fishing journalist group.
With a focus on fisherman, 240 people in total
participated, and data of about 140 points and 8,000 fish
is collected.（http://www.meic.go.jp/edohaze）
http://www.meic.go.jp/）。Therefore, these are became
evident; average of fishing outcome is 20 fish perperson in one hour in this season, and average of theentire length is 9 cm in July, 10 cm in August and 12 com
in September. And along with it, effectiveness offeaturing spiny goby as a symbol for Tokyo bay
reclamation was indicated and it was presented in the13th Tokyo Bay Symposium and placed in fishingmagazines.

River mouth and cove are effective, because small individual
can become established.
Marine area where is not dysoxic environment will be needed.

Joyful use of urban tidal flat research team
Activation of activity as a citizen beyond area andaffiliation are one of the important elements to promoteICM.
（ http://www.meic.go.jp/wiseflat ） 。 Participatory
abode of creatures search research was conducted in anurban maritime park (Takashimasuisaisen Park) that has atidal pond. （ http://www.meic.go.jp/wiseflat ） It was
experienced as follows; worm digging research by tidal
flat team of the tidal pond, and shrimping and goby
fishing research using the worms by tidal pool team.
It was found as a potential desire for sea natureexperience through these efforts. And those will
hopefully be a momentum of ICM.
