In Friuli Venezia Giulia countless waterways are home to a wide and rich variety of fish species. But there are some fish that, more than others, are the dream of every fly fishing and lure fishing (spinning) lover, especially in the mountains. The marble trout (Salmo trutta marmoratus) is undoubtedly one of the most prized catches because of its strength and colourful livery. It is the quintessential native fish of this territory. The brown trout (Salmo trutta fario) is the symbol of fast-flowing torrents and the high mountains. Moving down the valley, the grayling (Thymallus thymallus) is the symbol of the history of fishing in Friuli Venezia Giulia. And who can forget the brook trout (Salvelinus fontinalis) and the arctic char (Salvelinus alpinus), the voracious predators of the lakes at high altitude.
