Dendrogram of the effect on cod stock of different fishing exploitation and smartness patterns.
Different combinations of exploitation (F = 0.1 to F = 0.4 and open access) and smartness (s = 1–10) for the different temporal and spatial distributions of NEA cod biomass over the simulation period are shown. Agglomerative hierarchical clustering (Lukasová, 1979) level four is shaded and the horizontal axis measures the dissimilarities between clusters in terms of squared Euclidian differences.
