Observation of Izumi River Ikimono Observation

Report on the results of Izumi River Aquatic Biological Observation Meeting (conducted on May 23, 2015)
On Saturday, May 23, 2015, a creature observation party was held at the waterside of Futatsu Bridge in Izumi River.
The day was blessed with the weather, and I was able to see many creatures.
| Creature species | Name | Remarks |
|---|---|---|
| Fish | Abrahaya | Indicator species of rivers that are "very beautiful" in Yokohama City's river biological index |
| Fish | Oikaiwa | |
| Fish | Loach | Indicator species of rivers that are "beautiful" in Yokohama City's river biological index |
| Fish | Groove | Indicator species of rivers that are "very beautiful" in Yokohama City's river biological index |

| Insects | Coonyanma | Larvae (yago) |
| Insects | Colour cocktail | |
| Insects | Sibosoyanma | Larvae (yago) |
| Insects | A member of the zebra | |
| Insects | A friend of buyu | |

| Others | Beetle | Indicator species of rivers "somewhat dirty" in the river biological index of Yokohama City |
※For details on water quality evaluation, please see the biological index (PDF: 658KB) for water quality evaluation. The waterside of Futatsu Bridge corresponds to the source-up upstream basin, so the index of the source-up and upstream basin are used.
※Since the index species has a wide range of habitats (water quality class) for index species, the water quality class where two or more index species have been confirmed is used as the water quality evaluation value at that point. From this result, it was found that the waterside of Futatsu Bridge is a "very beautiful" river.
Voices from the participants
- It was found that the Izumi River had a lot of fish.
- The river was cold and cleaner than I thought.
- It was meaningful to be able to observe creatures in a familiar place ...
