In many Asian countries, farming rice with crabs in paddy fields has become a popular practice. The crustaceans feed on insects that are harmful to the plants, helping them to grow healthier, while the plants provide them with shelter; thus, both grow in a beneficial symbiosis.

The best part is that at harvest time, the farmer harvests both the rice grains and the mature crabs.

Inspired by this practice, similar proposals are being explored in the Amazon. One of them is the cultivation of Camu Camu with fish farming.

The proposal, currently in the research stage, consists of creating floodable plots where fish can spawn safely under the branches of the Camu Camu tree, which provides them with food. Once the fish grow, some of them will return to the river, while others will become food and sustenance for those who cultivate the plant.

This proposal recreates the natural cycle during floods, where the Camu Camu plant is covered by water up to more than half of its stem while the fish feed on its fruits, spreading its seeds in their waste.
