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).
