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…

After more than two months of lockdown in which Italy had to stop due to the pandemic from Covid19, we finally start again with all due caution. Work is underway in Oratino to make the hatchery accessible to all, in the hope of reopening our facilities to visitors as soon as possible.

The photo shows us a genetically pure individual of about 50 cm caught just downstream of the entrance of the Rio Freddo in the main course of the Biferno. In the samplings of this winter and early spring we observed that a part of the spawners in the Biferno River go up the Rio Freddo,…

Among the various methodologies provided by our project, there is also the sowing of the larvae hatched in the hatchery and taken a few days before free feeding to avoid domestication. Here we are in Rio Freddo and we have just built a nest with the addition of plants and mosses that will provide protection…

Before sowing, we dedicated ourselves to the construction of nests in the main course and in the sides of the Volturno river. The main course of the Volturno river was heavily hit by the floods of last autumn-winter and, following the monitoring carried out, we recorded a severe depletion of the salmonid population. For this…

5,000 native trout eggs from Molise, genotyped and fertilized with cryopreserved semen are ready to hatch, protected in their nests rebuilt directly in the rivers they belong to. Reintroducing embryonic eggs of S. magrostigma native trout into the nests is a key factor to support natural reproduction and to support the recolonization of the project…

As we have already said elsewhere, the first step is to select the breeding stock. The specimens are captured, temporarily retained and genetically characterized (or recognized, if already marked). Male migration begins first, therefore the semen is taken first, which is put to freeze in the cryobank. Subsequently the eggs are taken from a certain…

It is spring and the embryonic S. macrostigma eggs, fertilized this winter partly with fresh seed, partly with frozen one, are close to hatching. For this reason we must hurry and bring them to their rivers: despite the pandemic, in fact, the NatSalMo technical staff – with all the necessary precautions and strictly observing the…

Even in this period of pandemic from Covid-19, in our project there are some invaluable actions that must absolutely be carried out in order not to risk nullifying the work done so far. One of these is the topping up of liquid nitrogen in the cryobank containers of the native Mediterranean trout seed, the first…

In the municipality of Oratino, in the Bivaro area, the project staff recovered the old wash house by cleaning it and transforming it into an hatchery. The major obstacle to implementing this transformation was due to the impossibility of installing air conditioners to refrigerate the water necessary for optimal incubation of the eggs. But thanks…
