The project technical staff spent the whole month of December on the Volturno looking for native Mediterranean trout males for sampling and taking the new semen to be used for the new upcoming fertilizations and for the cryobank. In search of males on the Volturno:

Installation of the cages in the Volturno river
Our technical-scientific staff has spent the last few weeks on the Volturno to install the cages necessary for the capture of the males going up to the breeding sites. In the video, some specimens captured and sampled:

Monitoring also ended on the Biferno
On the Adriatic side, the substantial stability of the Biferno in recent seasons has favored a natural increase in the youth stadiums, which our technical staff has found in large numbers even at the mouth of those small spring streams that had been identified as suitable sites for the enhancement of reproductive capabilities. One above…

The three types of behavior of male trout in the reproductive period
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…

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…
