A propos de Lisaqua
Fondée en 2018, Lisaqua est une start-up deeptech à impact qui élève des crevettes dans des fermes aquacoles indoor terrestres, sans impact sur l'environnement.
Sa mission : produire mieux, avec moins de ressources.
Grâce à sa technologie brevetée, Lisaqua propose les premières crevettes fraîches, garanties sans antibiotiques ni conservateurs, élevées en France.
Après 5 ans de R&D, Lisaqua a lancé la première ferme de crevettes en France, à Saint-Herblain (Nantes) et produit 10 tonnes de crevettes par an. L’entreprise passe l’échelle supérieure avec la plus grande ferme de crevettes d’Europe, en Seine-et-Marne en 2025 (500t/an).
L’ambition de Lisaqua est de devenir leader de l’aquaculture saine et durable, et déployer un réseau de fermes en France et en Europe pour produire plusieurs dizaines de milliers de tonnes par an. Les crevettes de Lisaqua, locales et respectueuses de l’environnement, seront ainsi accessibles au plus grand nombre.
