Sažetak
Allocated zones for aquaculture in Zadar County (Croatia) were determined through the Integral Coastal zone Management procedure. The environmentally acceptable capacity of each zone was supposed to be determined following the environmental impact assessment. In order to assess environmental impact on seabed of sea bream cage farm for a desired breeding capacity, three cage spatial stocking schedule scenarios were analysed. The analysis was performed using emission estimates and modelling of dispersion and deposition of organic matter on the seabed with concomitant effect on the oxygen concentration. The emission was estimated according to fish growth prediction, fish energy needs, fish body chemical composition, the amount of (industrial feed) daily meal and feed proximate chemical composition. The simulation results show that optimised design of spatial fish cage stocking can significantly reduce the environmental footprint thus allowing increase in annual production to optimally utilise the farming site. Additionally, the obtained results suggest that the determination of carrying capacity of the farming site based only on produced fish biomass does not give optimal estimates and could contribute to an under- provision of the cage fish farm productive capacity.
