Villagonzalo II is the only coto in Spain where hucho hucho (Danube salmon) can be legally targeted — a nearly 3 km stretch of the Tormes downstream of the trout beats. The Tormes hucho population originates from introductions beginning in 1968, with the present stock maintained by periodic releases concentrated in this section. The Castilla y León species guide describes hucho as a fish of large, flowing middle-river sections — fundamentally piscivorous, holding in deeper, more substantial water than trout. This is not delicate fly fishing; it is predator fishing in salmonid water.
