In Slovenia there is estimated to be around 10,000 individuals of the pure species at seven locations with a combined area of occupancy (AOO) of <20 km². The subpopulations in Italy need more research, as more subpopulations are likely to be found in addition to the three already identified. The stocking of foreign trout continues and may reduce population numbers of genetically pure marble trout. However, the populations in Slovenia, and to a lesser extent in Italy, are safe and have no major widespread threats (Crivelli, A. pers comm).
