Table 5: Number of fish species recorded by Projet Lac in each lake. Cells are shaded to highlight differences among lakes. Note that the number of species can be influenced by sampling intensity: electrofishing was not conducted in Annecy and Bourget, and the vertical gillnet protocol was not conducted in Annecy, Bourget, Idro, Iseo, Varese, Como and Mezzola.
