2017 [Hamako Ayu Run-up Project] The second working was held! !

On Saturday, August 26, the second working of this year was held!
Katabira River is also a theme of "Let's learn about Katabira River!"
See if it's a river! Know! Think about it! We have conducted a field work for you!
On the day of the fine weather, everyone went into the river and learned about various Katabira River!

Let's look back on the situation and results of the day!

The program of the day was like this! Held on June 24
Based on the content of the first session, a new flow velocity survey was conducted, including the viewpoint of monitoring.
We made an effort to learn about Katabira River!

After explaining today's schedule at the new Asahi Ward Office building, we left downstream of Suidobashi, the venue for casting nets!
On the way, visit the Tsurumine Hashimoto-style fishway just completed this year!
The results of a run-up survey that could not be reported in the previous working came out, so I checked the results!

Before setting up the fishway, many ayu that could not be confirmed on the upstream side of the head work was confirmed!
Ayu is definitely going to go up with the maintenance of the fishway!

↓　↓　↓

The children are crazy about what was caught in the cast net!
What was captured? ？
・・Yes!　It's Ayu!
Ayu is definitely coming up!

Participants have a ball net and start investigating creatures!
From children to adults, everyone went into the river and looked for creatures!
In the water quality survey, five waters were arranged and the difference was confirmed!
The children are also helping with the survey!

※Results of the survey of creatures

Table (right): 2nd Working August 26

Compared to the first working, the type and number of living things were smaller, but I was able to meet new creatures such as Mokuzu Crab and Japanese dace that could not be collected at the first time!

　

In addition to river creatures, I was able to see many creatures and see the biodiversity of Katabira River!

※Results of water quality survey
The results of the water quality survey were as follows. While many creatures live there
It turns out that the water quality is not yet clean.

※Results of the flow velocity survey
We had children conduct a simple flow velocity survey using ping-pong balls and octopus threads!

Lunch break

↓　↓　↓

After lunch break, we will conduct a cleanup operation in the afternoon! In the morning, we conducted a biological survey to clean up the Katabira River. This time, a lot of garbage was collected, such as vinyl wrapped around tree branches, etc., due to the heavy rain that fell the other day.
A lot of large garbage, such as iron pipes and DVD players, was also collected.
Don't throw trash into the river!

Many people participated!
Thank you very much! ！
