With the effort of Slovenian fishing enthusiasts, the “Marmorata” population has well recovered.

Marble Trout Anyone?

Marble trout (Salmo marmoratus; Cuvier 1817), endemic species, in Slovenia also known as Soca trout. The large head is one of the characteristics (taking around one fourth of the body length) which is predominant in the species, while huge variation in size and color between the habitat types exist.

In chalk streams the marble trout tend to grow stouter and may reach trophy dimensions, while in the upper reaches of Alpine rivers they grow smaller in size. In general, anglers distinguish between Idrijca sub-type marble trout, being yellowish to olive in coloration, with possibility of having an off red mark on body. While Soca sub-type is less pigmented, with almost grey marble pattern.

The big ones grow to 130 cm (51 inch) and weight up to 22 kg (55 lbs). Realistically all fish over 70 cm (26 inch) may be considered a very good catch.  Its colouring and marbled pattern changes from river system to river system.

Specifics of Marble trout fishing:
Solid sized marble trout up to 60 cm rely on insects diet and are therefore targeted with classic fly fishing techniques – long line sight nymphing, in faster waters with short line nymphing and high sticking and when the hatch is on also on a dry fly. The larger specimens are exhibiting predatory lifestyle and are targeted with larger or/and heavier streamers.
