[Silver] October 28, 2010 12:30

On October 23, we saw the following information and applied for and participated in the survey. .

"Information from the Asashio Canal Renaissance Council!: fune:: fune:

The Asashio Canal is an area where one of the few shallow areas left behind in the inner part of Tokyo Bay: -o.
The shallow area is an important place for the growth of living things, and is especially important place for the sanctuary of goby fry and undeveloped fish that represent Edomae.  We conduct a goby fishing survey so that everyone can reaffirm the importance of the Asashio Canal: -D: fune:. 」

 It was an event that everyone thought seriously so that the redevelopment would not destroy the growth environment of the goby. 

 By the way, on the day, in addition to the officers of the council, Mayor Mihide Yada also appeared and gave a greeting.

 Tokyo Port and Harbor Bureau, Chuo-ku Civil Engineering Department, Tokyo Fisheries Promotion Association, National Environment Promotion Association, Ministry of Land, Infrastructure, Transport and Tourism's National Institute of Land, Infrastructure, Transport and Tourism, Ocean Research, Tokyo Island Agriculture, Forestry and Fisheries Research Center, and NPO Seaside Building Study Group participated in the event with care. After the explanation and attention from Mr. Imai, the director, boarded three ships.

 In water quality tests, salt content is 2.7%, water temperature is 21. C, DO (dissolved oxygen) is 2.6 in the surface layer and 1.5 in the lower layer.

In other words, it seems that there is little oxygen. (By the way, you need 4 oxygen to cultivate red sea bream.)

The goby cannot live without this mud left. Yes, in an environment like a plastic aquarium, ordinary creatures cannot live. If you're too clean, fish can't live.

 The white heron was flying. 

That's also living in harmony with the fish living here and in the food chain.
