Multi-Criteria DEXi Analysis for the Selection of Crop Species for Saltwater Aquaponics

Saltwater aquaponics is a sustainable alternative system for food production. The success of this largely depends on the selection both fish and plant species, which several features criteria must be considered. This paper aims to identify most suitable species saltwater by using multi-criteria decision-making method also based current literature. One simple model that contained one root criterion, four aggregated criteria, sub-criteria was created DEXi software. same evaluated considering two different salinity levels in recirculating water: 10 (brackish water) 35 (sea g L−1. relevance structure sensitivity analysis, through ‘plus/minus-1′ analysis.
