Fishing Without Nets
A whale and a baby dolphin show that you can feed yourself from the sea without exhausting the sea.
What this fable teaches
- •That fishing techniques inspired by humpback whales exist, replacing nets with a bubble net.
- •That protecting mother fish guarantees the balance and survival of species over time.
- •That an idea observed in nature can become a method actually used by fishing communities.
- •That protecting a resource and continuing to live from it are not two opposing goals.
The activity to do together
Draw or model with modeling clay the “bubble net” formed by the whale and the dolphin, to visualize how a circle of bubbles can replace a real net.
