At the Rocchetta a Volturno hatchery, during the EASME monitoring visit on 11 and 12 February, we observed through a digital microscope an egg that we had fertilized in early January with the cryopreserved seed. When fertilization is successful, at a certain point of the incubation those two black points appear, which correspond to the…

The cryobank on Dire.it
The press release on the first European cryobank of Mediterranean trout seed created by Unimol thanks to LIFE NatSalMo had considerable success, not only in the traditional press (see the press review), but also in local and national news. At the link, one for all, the Tg di Dire.it, a national press:
The cryobank and the protocol for cryopreservation of native Mediterranean trout semen: an excellence of the NatSalMo project
The cryobank of the semen proved to be an effective strategy to protect the biodiversity of some fish species and the cryopreservation protocol, originally developed for farmed salmonids, was tested for the first time on the sperm of wild native trout that populate the Molise rivers by the scientific project staff. Thus was born, in…
January 2021 on the Volturno river
January is the main month for spawning in the Volturno River and its sides. Females mature their eggs, approach breeding sites, build nests and deposit thousands of small yellow eggs there. The color is due to the yolk which will be the nourishment first for the embryo and then for the newly hatched larvae (the…
The circles of deposition of the scales in the trout
To know how to protect a species and manage the human activities connected to it, it is important to know its biological characteristics, dynamics and behaviors. The age, the growth rate of the trout and therefore the length reached at the first reproduction are decisive parameters. To estimate the age of the fish, we can…
The semen collection on the Volturno: season ’20/’21
In December, the semen collection of the native Mediterranean trout individuals on the Volturno River began. Here in particular the staff is on the Lorda, here are the first images:
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…
