The moats surrounding the Imabari castle are filled with water through a channel connecting to the ocean (visible in this photo as a small black rectangle in the center of the image).
The salty water is mixing with the fresh water springing in several places of the moat, and this created a unique ecosystem, in these moats living together both fresh and salty water fishes.
