This project aims to design, implement and validate a modular integrated multitrophic aquaculture system (IMTA) for the production of marine and brackish water species, with emphasis on sea bass (Dicentrarchus labrax), oyster (Crassostrea gigas), ragworms (Hediste diversicolor), sea asparagus (Salicornia ramosissima) and sea lettuce (Ulva sp.). The different combinations of IMTA modular systems to be evaluated will be fully equipped with in situ and ex situ real-time monitoring systems, thus allowing their monitoring through the cloud, as well as the correction of physico-chemical parameters through automation solutions (which will also be implemented). The life support systems that will be developed will also test the viability to operate on a 100% reuse water regime (designated as zero water exchange).
