In the video and in the photo you can see two specimens of male trout while side by side they feed in peace, without fighting each other. This happens because they are not yet in the reproductive period, otherwise we would see them as rivals and fighters. In fact, it is known that in salmonids…

Autumn samples – Carpino stream
The genetic analyzes of the first year of the project had revealed, in some peripheral basins of the Volturno River, the presence of resident (non-migratory) populations with a discrete component of indigenous genetics. We are now continuing these investigations to discover, before the breeding season, the possible presence of pure source populations to be used…

Autumn Samples – Rio Santa Maria
In recent weeks we have carried out monitoring in the Biferno basin in Santa Maria del Molise (Rio Santa Maria), where we had placed artificial nests last spring. Here are some of the individuals from whom tissue samples were taken for DNA analysis. The numerous parr spots (narrow and elongated), typical of Mediterranean trout, bode…

In addition to the finalization of the hatchery, before the next breeding season there will also be an educational center with a multipurpose room, for conferences and face-to-face meetings that we hope to be able to organize as soon as we are in…

Acquatrekking always and anyway? No thanks!
We were inspired by a reflection by Alex Vigliani, an expert environmental hiking guide, to ask ourselves whether or not to practice this “sport” that is becoming popular in our territories. For those few who do not yet know it, it is a matter of practicing the walk not only on land, but in the…

Summer trout ascent in the Biferno
Slow motion emotion: in the tributary streams of the Biferno we managed to film some specimens in ascent! In fact, with the summer storms, the instinct of the ascent pushes the trout to explore the upper quadrants of the rivers and streams in which, in the winter months, they will reproduce.

The parr spots
In the sampled specimens, in addition to genetic analyzes, morphological ones concerning 7 phenotypic classifications are also carried out, including the analysis and comparison of the so-called “parr spots”. It is a matter of observing 9-13 large ellipsoidal blue-grayish spots present along the median region of each side, sometimes divided or fragmented and / or…

The first fry of the 2020 season
The photo is not that great, but it is the first documented native Mediterranean trout fry, born in an artificial nest of the Rio Santa Maria, the result of fertilization with cryopreserved seed. The success of the sowing activities can only be assessed by monitoring the next few years, but in the meantime numerous fry…

Volturno trouts
One of our cages for the control of the breeding was positioned in the Rio Caprionero, because it is from there that the trout from the Volturno river go back to go to reproduce. In fact, the main course of the river, although it has a good substrate for reproduction, is vulnerable due to the…
