Leitat has a strong focus in the development of technologies around aquaculture. This is very relevant to Mediterranean countries, as the Mediterranean sea is overfished. Aquaculture offers an alternative way to sustainably produce fish and seafood. In particular, Leitat often works in technologies supporting integrated multitrophic systems or IMTA systems, where several species of fish, mollusks and algae are grown together within an interconnected system. This is more similar to natural ecosystems than growing a single species, and results in a more sustainable and circular system.
