Apparently, Eileen's mother used to buy fish from a professional fisherman at Lake Cargellico, she claims that the catfish was the best eating of all the native fish! They have the added advantage, that they will breed if there is a gravel bottom in the dam, ( I though because of the cold here, it would take some time to reach that stage). Of course there are the natural predators to deal with, shags, cranes etc. And like our fruit trees (not to mention rabbits), the dream is the thing, reality another matter.
