The sustainable fishing is an example of sustainable development.
Explanation:

A good example of this is the sustainable fishing.
The sustainable fishing is performed in a manner that strictly regulates the amount of fish that is fished, in what period should the fishing go on, the size of the fish, as well as the species of fish. This results in leaving the fish to reproduce freely, always having high enough number for reproduction, releasing the young fish if caught, and having good supply of fish each year. This benefits the fish, the economy, the diet of the humans, and the well being of the environment.
