When moving from a very sheltered aquaculture site to a very exposed oceanic site, the energy increases proportionally in a continuum. Lojek et al. (2024) considered the primary influential parameters (water current, waves period, water depth) which dictate the candidate species, structure, technology, methods, and operational aspects of any aquaculture endeavour and investigated six possible indices which cover these variables. Added to advanced computer modelling, assisted by detailed and constant environmental monitoring, it may be possible to refine site selection, structure and design decision , species selection, equipment and logistic considerations and health and safety requirements. This paper will discuss the benefits of two selected indicative indices from the potential equations and compare them with known operational aquaculture sites highlighting present structural capability and limitations. The two indices are also utilized to reflect on their suitability for assessing sample sites with respect to biological, technological, operational or maintenance aspects of aquaculture activities.
