Mergozzo Lake and its fish: a source (at risk) Biodiversity

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.

Acerina ( Gymnocephalus cernuus), a major problem ... "prickly"
The coastal zone management, containment of invasive species and the modulation of collection of valuable fish species, are key pieces for the maintenance of good environmental status of this small lake.
