Figure 21 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report

Figure 21: Significant correlations between whole-lake average biomass of large fish caught in Projet Lac vertical nets and corresponding yields of (the sum of) commercial and recreational fisheries in kilograms per hectare per year in large and deep lakes (average depth> 50 m) for Coregonus spp (left; p-value = 0.03, R2 = 0.51) and Perca fluviatilis (right; p-value = 0.053, R2 = 0.43). Maggiore, Lugano and Garda are not included, as reliable data on recreational fishing catches were only partially available.
