Effective and Low-Maintenance IMTA System as Effluent Treatment Unit for Promoting Sustainability in Coastal Aquaculture

Integrated multitrophic aquaculture (IMTA) is a versatile technology emerging as an ecological and sustainable solution for traditional monoculture aquacultures in terms of effluent treatment. Nevertheless, IMTA still poorly applied industry due to, among other reasons, the lack effective, low-investment low-maintenance solutions. In this study, one has developed practical low maintenance IMTA-pilot system, settled semi-intensive coastal aquaculture. The optimisation performance system was validated using Ulva spp., macroalgae that naturally grows fishponds local Several cultivation experiments were performed at lab-scale static mode. specific growth rate (SGR), yield, nutrient removal, N C enrichment, protein pigment content monitored. spp. successfully thrived from fish species sea bream (Sparus aurata) bass (Dicentrarchus labrax) production tanks significantly reduced inorganic load effluent, particularly, NH4+, PO43− NO3−. enrichment nitrogen spp.’s tissues indicated assimilation by algae, though, cultivated showed lower amounts pigments comparison to wild type. This study indicates designed efficient treatment suitable remediator.
