AZA4ICE methodology

This document aims to detail the testing methodology to guide the Project Partners (PPs) in defining the Allocated Zones for Circular Aquaculture (C-AZA) in the eight identified pilot sites throughout the Mediterranean and Black Sea basins. In particular, the steps outlined in this document encompass data collection, assessment of site suitability and species suitability, evaluation of suitable IMTA/RAS models and circular practices, presentation and evaluation of the results, and data evaluation through the stakeholders’ involvement. The number of steps to be applied varies depending on the type and main features of aquaculture activities developed in each pilot case study area. Specifically, the "site suitability" is the initial step of the C-AZA methodology when aquaculture activities are either underdeveloped or even absent, while it can be skipped if the sector is consolidated, and it represents a well-established activity in the area. This step is followed by the "species suitability", based mainly on the physiological tolerance range, technological culture development, the environmental characteristics of the water body considered, the market demand, regulatory requirements, and on the economic feasibility. The species suitability represents the baseline for the final step of the C-AZA methodology, the "circularity suitability" assessment. By following the C-AZA methodology, PPs can systematically define Allocated Zones for Circular Aquaculture in the targeted pilot case study areas, ensuring alignment with project objectives, stakeholder needs, and sustainability goals. The outcomes obtained from the implementation of the C-AZA methodology can assist decision-makers for efficient planning of aquaculture activities in close-to-coast and inland waters based on an ecosystem-based approach aligned with European policies, including the European Common Fisheries Policy, the Farm to Fork Strategy, the Sustainable Blue Economy, and the European Green Deal.
