Recenti indagini svolte sul Lago di Mergozzo testimoniano la ricchezza della fauna ittica di questo piccolo ambiente lacustre. 19 specie di pesci vivono nelle sue acque pulite e cristalline.
L'agone ( Alosa agone ), il coregone lavarello ( Coregonus lavaretus ) e l'alborella ( Alburnus alborella ), specie ittiche con elevato valore ecologico e naturalistico "onorano" il lago con la loro presenza nella zona del pelagica.

The area of \u200b\u200bthe bank is instead inhabited by many species, some well-known as the pike (Esox lucius ), the perch (Perca fluviatilis ), the rudd ( Scardinius erythrophthalmus) and other less well-known as the goby Po ( Padogobius martensitic) or the gudgeon (Gobio gobio ). In the deep zone
instead live a few species that need fresh water and oxygen: char (Salvelinus alpinus ) and burbot (Lota lota ).

Unfortunately these are also in some non-native species mass measurement of a recent outbreak that might endanger the balance of the ecosystem.
The roach (Rutilus Rutilus ) and Acerina ( Gymnocephalus cernuus) in fact are currently the most abundant species in the area of \u200b\u200bthe shore, and in the case of roach, including surface water in the lake center.
