The dataset provided by Panzeri et al. (2023) in the context of spatial fisheries management in the Adriatic Sea comprises: Ensemble Density Map: This dataset visualizes the distribution of various marine demersal species, both juveniles and adults, across the Mediterranean Sea. It quantifies the density of these species in each grid cell, represented by longitude and latitude, in terms of the number of individuals per square kilometer. Getis Hotspot Map: Built upon the ensemble density map, this dataset employs the Getis-Ord Gi* statistic to pinpoint significant clusters or 'hotspots' of fish aggregation. These hotspots are identified for each species and life stage, offering detailed insights into critical areas for fish concentration. Multispecies Hotspot Frequency Map: This map extends the hotspot analysis to a multispecies perspective. It represents the frequency of overlapping hotspots for different species, based on the number of species with significant hotspots above a defined threshold in each grid cell.
