Sažetak
Mariculture is an ever-growing sector with increasing energy needs. Energy intensity depends on cultured species, production technology, organization, and local conditions. Nowadays, the fluctuations in oil prices significantly affect the energy sector and it is evident that long-term sourcing energy from fossil fuels will not be sustainable. Similar can be noticed for the mariculture sector where (especially in the case of cage-based farms) a high share of fossil fuels is used, but at the same time, the energy cost and corresponding implications for carbon and other emission are drawing much attention. Existing references in the field already consider the integration of alternative power options into mariculture farms, with emphasis on renewable energy sources (RESs), claiming that both environmental and economic benefits are achievable. This paper analyses the effect of price fluctuations of selected alternative energy sources on the economic sustainability of mariculture systems, where the energy needs of a typical mariculture farm and corresponding working vessel in the Adriatic Sea are considered in a long-term framework. The results indicate that share of alternative power sources in mariculture systems can be increased without compromising economic indicators. Therefore, bearing in mind their environmental friendliness compared to diesel, the use of alternative fuels in mariculture systems should be encouraged. Finally, recommendations for the design of energy systems for future mariculture farms are drawn.
