2022 Miyakawa River Creation Activity Record

Talking about the relationship between grass and dementia

This time, as the "4th Miyakawa Medaka School", "Miyakawa and surrounding creatures" and "dementia and grasses" as "4th Miyakawa Medaka School".
He talked about the relationship between the two countries.

In the story of "Miyakawa and surrounding creatures", as a result of a survey by setting up a net in Miyakawa, mahaze and lobster were found.
He told us about what we were able to capture.
In the "relationship between dementia and weeding", why weeding is related to maintaining health, and weeding is the heart.
He explained the impact on the person.
In fact, participants performed stretching, etc., which is said to affect brain activation, and enjoyed it.
I was able to learn about the relationship between dementia and weeding.

History of Kamariya

This time, as the 3rd Miyakawa Medaka School, people familiar with the history of the region are Kanazawa Ward and Kamariya.
He talked about the history of the region.

The warlords of the Kamakura period and the Kamariya district, which are closely related to the Kanazawa Ward, came to be called "Kamariya."
He gave an easy-to-understand explanation while presenting the materials.
Knowing the history and background of the roads you usually go to and where you live.
It turns out that you can discover the charm, and it is important to know again about the area where you live.
I was able to feel the joy of pods.

Presenting about Miyakawa's creatures

This time, we announced what we know about the creatures that live in Miyakawa, exchanged opinions, and exchanged opinions.
I did it.

About black dai, mullet, crab, crucian carp, etc., convey characteristics and ecology while presenting photos, and conveying emotions.
I shared the news.
In addition, some of the participants were familiar with medaka, so about breeding methods and spawning.
I told you in detail.

Next time, as the 3rd Miyakawa Medaka School, we will introduce the history of Kamariya from people familiar with local history.
I'd like to talk about it.

Discussions on river-building activities next year

This time, the coordinator for river making will also participate in the next fiscal year's Miyakawa River making activities.
We had a discussion with you.

Because of the tide level, Miyakawa has decided when it is possible to enter the river during the day.
We exchanged opinions on what kind of activities we would like to do.
As a result, as a current plan, from May to October, we entered Miyakawa to conduct river creation activities, and from November to the next day.
Until March of this year, we decided to work indoors.
Activities include the creation of living creatures by stone-framed waterworks and the activities of the participants who are still conducting the activities.
There was a talk session "Medaka no School" held mainly by the people, and lively exchange of opinions was held.
I did it.

Next time, a river coordinator specializing in creatures will come and visit Miyakawa creatures.
I'm going to have you explain about this.

State of Miyakawa Medaka's School

The Miyakawa Medaka School, where local people play a central role in talking about the history of the Kamariya district and Miyakawa.
It was held.

This year, the first time, was the first time, from those who have lived in the Kamariya area for many years, the history of the establishment of the Kamari Yan Club and the kettle.
He talked about the history of the Toya district and Miyakawa, fireflies, etc.
"In the past, many eels lived in Miyakawa so that they could eat too much and hate them," and "camari"
The Young Club was originally started with volunteer activities to encourage children to experience nature."
I was able to learn about the precious local history that I could not understand from literature and records. .

Next time, I came to the river coordinator as the "2nd Miyakawa Medaka School"
We are planning to discuss next year's river-building activities.

Discussion

We talked about the activities of river making from November 2022 to March 2023.

In winter, it becomes difficult to enter Miyakawa, so indoors, talk about river creation and engage in activities.
We have decided to hold a lecture on the area by the members.
Lectures include not only the creatures and environment of Miyakawa, but also the history of the Kamariya area and volunteer activities.
I'm going to sit down.

Next time, we will carry out the first lecture by local people.

Work scene for repair of stonework

We conducted a survey on the status and repair of the stonework on the left bank of Miyashita Bridge downstream, and learned how to conduct sludge surveys together with the river coordinator.

The stonework installed in June has accumulated sediment, and the stonework was repaired using local stones so that the dried tidal flats could be further increased. Some of the stones were large and heavy, but both the children and adults of the participants worked together to carry the stones and work.

Regarding the sludge survey, the coordinator advised to determine the location, collect a fixed amount of soil, such as one scoop, from the survey point, spread it to a dry place to check color, smell, properties, etc. Was.

We will continue to create more rivers with the aim of clear Miyakawa.

Survey of Creatures

We conducted a survey of creatures around Miyakawa-juku Square.

On the day of the event, a river coordinator, an expert on living things, explained how to investigate creatures, and then examined creatures living in Miyakawa with a duck net from around 30 small children to adults.

After the survey, we heard from a river coordinator about the creatures captured by the duck net. The types of goby are increasing compared to the time of the creature survey conducted in May, and it seems that the effects of the houses and lobes of Ishigumi fish, which are being carried out in the Miyakawa River creation activities, were appearing.

Installation of Soda

Around Miyakawa-juku Square, we set up a house where creatures live and checked the status of the soil improvement demonstration experiment site.
While receiving advice from the river coordinator, a savory (soda) made by bundling bamboo trunks to become a habitat for creatures in the river, and a tidal flat shape so that crabs can be established Bamboo cylinders have been installed. In addition, when we collected creatures using nets, etc., we found that there were young chichibu fish and ubina gas shrimp in the existing stone group.

At the test site for soil improvement, participants tried to improve the soil using iron powder of disposable warmer for the purpose of improving sludge in April this year. This time, when I dug down the soil at this place, I was able to confirm Yamato Kawagokai.

In addition, this time, we extended our feet and observed creatures of Kamariyacho Ogawa Amenity in the upper part of the second-class river Miyakawa. The second-class river Miyakawa is affected by the tide level in the tidal zone, but this brook amenity is freshwater and is inhabited by Abrahaya and loach on the upstream side, allowing us to know the differences in living things depending on the river environment.

Installation of stonework

A soda was set up near the inn square in Miyakawa, and a stonework was repaired and installed near Teko Shrine. .
The slobe is a collection of small trees and branches. This time, thin bamboo branches are bundled and used.
This time, together with the river coordinator, we installed a lobes in the house where the existing stone-framed creatures live.
It is expected that the installation of savory lobes will further increase small creatures such as shrimp.

The Ishigumi water system is installed in the river channel by combining large and small stones, and aims to change the flow of river water and create a place like a tidal flat.
This time, we carried out two repairs of the existing stonework waterwork and one new stonework waterwork installation to reduce sludge accumulation.
Some of the stones were quite heavy, but about 30 participants installed together and were able to install them safely.

Scenery of biological surveys using tamo nets

A biological survey of Miyakawa (Yaku Square-Miyashita Bridge) was conducted.
While teaching the river coordinator how to survey creatures, we checked what kind of creatures are in the houses where stone creatures were installed last year.
Participants themselves surveyed using a duck net, and found creatures such as shrimps, crabs, bi apples, Chichibu, Mahaze, Ashishirohaze, and Ukigori. I once again realized the effect of having such a living house in the river channel.
