Nouvelles Fermes produces salads, vegetables, and herbs as well as rainbow trout in greenhouses. Fish droppings are used to fertilize plants installed on rafts, the roots of which are submerged.

In doing so, the water is filtered and can therefore return to the fish tank. An atypical but profitable model, which the company wishes to generalize on a larger scale, in Île-de-France. With half a hectare, the Mérignac farm produces 1% of the needs of the inhabitants of the metropolis in salads and 4% in trout. Aquaponics aims to participate in the reconquest of the country's food sovereignty while remunerating producers with dignity. The company is launching a fundraising campaign and hopes to raise 1.5 million euros by June 2024 and 15 million euros by the start of 2025. The idea is to build six hectares of farms in Île-de-France, on one or two sites, in the Greater Paris area.
