Searching for males on Volturno river – December 2020
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…
Completed the monitoring in the Volturno
The samplings for monitoring the results of the last breeding season in the Volturno river have ended. Now in the Unimol laboratories, the scientific staff is preparing to process the samples taken and to process the results of the genetic analyzes, ready in a few months: however, we can already anticipate something … On the…
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…
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…

Here are the trout from Volturno, the result of spring sowing and a lot of commitment and passion on the part of the project staff!
Work in progress in Rocchetta a Volturno.
The adaptation works in the hatchery of Rocchetta a Volturno proceed incessantly. 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…
