MARBLE TROUT, THE SLOVENIAN MYSTERIOUS SALMONIDS
Marble trout is a kind of Brown trout who lives in the south side of the Alps in the rivers that are tributes of the Adriatic Sea.
Sunny face of the Alps save one of the great treasures wished by fishermen from all over the world, the mysterious marble trout.
It is mainly distributed in Slovenia, Northern Italy and Croatia:
Marble trout is characterized for:
- Its strong territorial character.
- Marble pattern.
- Big size of head
- Large specimens of even more than one meter and more than 10 kg.
This specie two decades ago came to be cataloged as an endangered species. The main problems that their populations have are:
- Hybridization with brown trout from repopulations for fishing.
- Deterioration of the quality of the waters.
- Fishing with dead.
- Habitat reduction
THE PROBLEM OF MARBLE TROUT WITH BROWN TROUT HYBRIDIZATION
Several decades ago many of the rivers inhabited by trout in Slovenia were repopulated with brown trout and originated the hybridization of the Marble trout populations. Thus in Slovenian rivers like Idrijca, Bača, Vipava, Reka and Rižana you can find river areas where the two species live and there is a natural crossing between them.
The hybrid trout keep characteristics of both species like the irregular livery (marble trout) mixed with red points with white edges typical of brown trout.
It should be noted that Marble trout can not hybridize with rainbow trout.
THE MARMORATA TROUT, THE GREAT TOURIST ATTRACTION OF SLOVENIA
Although the Marble trout is found in various countries such as Italy, Croatia … it has been the Slovenian Fishermen’s Clubs that have known how to value this species. Nowadays Slovenia is known for its Marble trout all over the world.
In 1982, a campaign to save this species was started in the Soča River and today the headwaters of this river have a large population of this salmon that continues to increase year after year.
The average size of the Marble trout in the Soča. it is about 35 centimeters in the upper course and 40 centimeters in the middle course of the Soča river. Every year the fishermen catch some Soča trout weighing five to fifteen kilograms. The largest specimen registered to date dates from 1997. The trout measured 121 centimeters and weighed 25 kilograms.
