Figure 65 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 65: Example of a hydroacoustic transect showing a cross-section of Lake Neuchatel from south-east, near Font (can- ton Fribourg/Freiburg; left side of figure) to north-west, near Vaumarcus (canton Neuchâtel; right side of figure). The red-brown band represents the lake floor. Hydroacoustic echoes of single fish are visible in the open water, particularly in the upper 25 m (depth-scale shown in green on the right hand side).

Figure 73 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 73: Composition of fish catches among lakes in open water, pelagic habitats (to 75 m deep) according to CEN pelagic gillnets. Note that only three and four fish were caught in pelagic CEN nets in Varese and Idro respectively.
Figure 59 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 59. Comparison between common phenotype of subadult Salaria fluviatilis and the new, rare phenotype in Lake Maggiore. The upper four photos were taken with the fish in cuvettes with (left) and without (right) gravel. Lower two photos are of additional individuals of the rare phenotype in their natural habitat. Note the marble pattern on the cheek on the rare phenotype, instead of the diagonal face stripes in the common phenotype. Also the broad, dark midlateral band running along the flank instead of paired vertical bars.

Figure 29 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 29: Comparison of the number of instances a species was recorded in a lake by the different methods. All lakes where the three sampling methods (CEN gillnets, VERT gillnets, electrofishing) were applied are considered. The blue column represents the number of instances a species was recorded in a lake by each of the three methods. Green columns show the number of instances a species was recorded in a lake by only one method. Red columns show the number of instances a species was not recorded by one of the methods (but recorded in the other two methods) in a lake. The total number of fish populations considered was 533.
Figure 28 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 28: Proportion of the lake shoreline in a near-natural state (green) and un-natural, modified or artificial state (red) as determined during littoral habitat mapping in Projet Lac.
Figure 16 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 16: Depth distribution of fish abundance by species (individuals per unit effort) in pelagic habitats to 50 m deep accord- ing to deep-set vertical nets (fish in the 3 m of net close to the lake floor were excluded).
Figure 12 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 12: All components of fish species diversity increase with lake surface area: total number of species, number of native species (counting each endemic radiation as a single taxon), number of endemic species (including each radiation species), and number of non-native and exotic species. Slopes and intercepts varied among river catchments. In the upper panel, only the horizontal axis is on log scale, in the lower panel both axes are on log scale. Regression statistics are provided in Table 8.
Figure 9 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 9: Length frequency distribution of large perch among lakes. Data from benthic CEN nets to 20 meters deep. The num- ber of fish is adjusted for the corresponding gillnetting effort in the lake. Vertical axis is truncated at 0.5 fish per 100 m2 of net to focus on the occurrence of the larger fish. Arrows indicate the approximate length of fish at which permitted nets for com- mercial fisheries become efficient. There was no commercial fishing in lakes Bret, Bonlieu, Chalain, Saint-Point, Remoray and Rousses at the time of Projet Lac sampling. No minimum size limit for perch in Annecy and Bourget. Lakes Biel and Sarnen are excluded as the different mesh sizes used in the Projet Lac sampling of these lakes influences the fish length frequency distribution, meaning that it is not possible to directly compare them to other lakes.
Figure 27 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 27: Contribution of two non-native fish species, Gasterosteus aculeatus (pink) and Gymnocephalus cernua (brown), to fish abundance in CEN gillnets set in the benthic (left) and pelagic (right) zones of Upper Lake Constance. The proportion of native species is represented in grey.
Figure 8 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 8: Length frequency distribution of Coregonus spp among lakes. Data from deep-set vertical nets (set deeper than 5 m). The number of fish is adjusted for the number of vertical net batteries deployed in the lake. Vertical axis is truncated at 0.3 fish per vertical net battery to focus on the occurrence of the larger fish. Arrows indicate the approximate length of fish at which permitted nets for commercial fisheries become efficient. There was no commercial fishing in lakes Chalain, Saint-Point, Remoray and Rousses at the time of Projet Lac sampling. Lakes Biel and Sarnen are excluded as the different mesh sizes used in the Projet Lac sampling of these lakes influences the fish length frequency distribution, meaning that it is not possible to directly compare them to the other lakes.
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.
Figure 20 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 20: Whole-lake average number of fish of Coregonus spp per vertical net battery compared to total phosphorus concentration in large and deep lakes (average depth> 50 m). First panel shows the relationship for all Coregonus caught in the lake. The other panels shows the relationship when only fish larger than the size thresholds shown at the top of the panel are included (length measured from snout to the tip of the tail). Note that the horizontal axis is on a log scale. Dashed red lines indicate statistically significant relationships (from left to right: p-value = 0.0001, R2 = 0.79; p-value = 0.008, R2 = 0.52; p-value = 0.87, R2 = 0.003; p-value = 0.412, R2 = 0.09). Shaded regions show thresholds for total phosphorus of 10 μg / L and 5 μg / L.

Figure 7 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 7: Whole-lake community composition based on CPUE in vertical nets. Upper panel shows volume-weighted aver- age number of fish per 100 m2 net area. Lower panel shows volume-weighted average biomass per 100 m2 net area. Figure includes only lakes surveyed by the standard vertical net protocol. Lakes Sarnen and Biel were sampled with a modified protocol and are excluded here. The smallest lakes Bret and Bonlieu are also excluded. Note that sequence of lakes along the X axis differs between the panels.
Figure 11 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 11: Similarity of the native fish species assemblages among lakes sampled by Projet Lac depicted by hierarchical cluster analysis (Sørensen index based on presence/absence of taxa; complete linkage). Lakes joined by shorter branches share a higher proportion of their fish species. Colours indicate river catchments: red = Rhine, green = Rhone, orange = Po, blue = Danube. See Figure 82 for an exploration of factors driving differences in the fish communities among lakes within catchments.
