Once upon a time, there was a small stream in a forest where different species of fish lived. They had a happy life, swimming and spawning in the cool water.
One day, the humans built a hydroelectric power plant upstream. The water level raised and the fish had to migrate to another tributary. But they soon realized that the new stream was not safe, as a big predator was living there.
The young fish, called juveniles, were scared, but then they had an idea. They remembered that the humans also built a hatchery and an irrigation system for the nearby crops. So, they decided to ask for help.
They swam to the hatchery and started jumping out of the water, trying to catch the attention of the humans. They were successful, and the humans understood their problem. They built a big reservoir to protect the fish from the predator.
From that day on, the fish were safe and happy again. And the humans learned that sometimes, even the smallest creatures can teach us important lessons.
Years passed and the humans continued to take care of the fish. And the species never became extinct, but instead, thrived in their new home.
The end.
