The role of aquaculture in the supply of fish in the future is undeniable. Aquaponics is a sustainable method to rear fish (aquaculture) and plants (hydroponics). The water enriched with nutrients from fish and feed wastes are used as a natural fertilizer to plants while these purify the water that goes back to fish. It is a water cycle that results from a symbiotic ecosystem and a good example of good water use and circular economy. School farming is a project developed for schools that was launched in 2022 in Lisbon, Portugal, aiming to be a learning tool to stimulate children´s motivation and interest in sustainability, water usage, healthy food eating habits and food security. The project consists of building an aquaponic system which includes a fish tank, a plant growing bed and a set of filtration and pumping equipment in a classroom which all students can have access to. Each class will follow the growth of different vegetables such as lettuce, basil and peri-peri, depending on the school level as different plants require different levels of care. At the same time, they will feed the fish and observe that fish waste works as organic fertilizer for plants. At the end of the cycle, students will measure the biomass of plants they have grown and compare the results with other classes and schools through a school farming mobile digital network. The implementation of these projects in developed countries has specific goals but its application in developing countries, where food insecurity is higher, can have a major importance as it will provide children knowledge and tools that can have a higher impact not only in their own homes, by replicating small scale farms, but to their future as it can stimulate their entrepreneurship skills to reduce poverty and foster food resilience. In this study, the results obtained by a secondary school will be presented in terms of fish growth and vegetable harvested during the first six months of the project. Carp juveniles of approximately 20 g were introduced in 500 L plastic tanks in December 2023. The grown vegetables included lettuce, cabbages, rocket, aromatic herbs, among others.
