By car, from Riva del Garda we take the tunnel which in about 10 minutes leads to the Val di Ledro. After the last gallery, 100 meters on the left side there is the small village of Biacesa. Here we find one of the most ancient trout-farm of the area (Troticoltura Armanini), established in year 1936, it makes use of the rich spring water originating from the near mountains which allows the breeding of a very appreciated variety: the Salmerino, a sort of small salmon. Three are the importanter raised exemplary: the Trout Iridea, from the typical iridescent band on the side, the Salmonata with rosy meats, breeded with special biological foods and the Salmerino, appreciated and not too much diffused salmonid, elegant in the forms and with meats with a delicate and a particular taste. It is possible to spend a few instructive hours to know how the trouts are breeded in a mountain fish-farm, looking the squeezing of the eggs, the cares for the fries, the pasture, the changes of tub up to reach the optimal measure for the sale.
