What animals did the ancients domesticate to help people fish?

The ancients once domesticated otters to help people catch fish.

Otters are omnivores. Although their fishing ability is not weak, they will not take the initiative to domesticate and raise fish to eat. In order to solve the problem of eating fish in ancient China, the ancients came up with a way to catch fish with otters.

The ancients put fish ponds in rivers, stocked enough fish for people to catch, and specially provided enough living space and food for otters, so as to better catch prey and meet people's needs. So it can be said that the ancients could use otters to help them catch fish.
