The sowing of the larvae 05 May

The sowing of the larvae

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…

Nesting in Volturno river 29 Apr

Nesting in Volturno river

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…

Nesting & Cocoonig: step by step a fundamental action of our project 07 Apr

Nesting & Cocoonig: step by step a fundamental action of our project

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…

Artificial fertilization of wild indigenous people: how does it work? 06 Apr

Artificial fertilization of wild indigenous people: how does it work?

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…

The eggs are close to hatching! 02 Apr

The eggs are close to hatching!

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…

The protection of the cryobank continues 01 Apr

The protection of the cryobank continues

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…

Oratino hatchery 04 Mar

Oratino hatchery

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…

Semen cryopreservation 26 Feb

Semen cryopreservation

One of the great innovations of our project is the creation of the first cryobank of the Mediterranean trout seed, a precious tool for the conservation and protection of the species. In January 2020, the project staff set up a mobile laboratory at the Rocchetta hatchery in Volturno to freeze the seminal material taken from…

Learning visit – day #2 21 Feb

Learning visit – day #2

At Biferno, Boiano locality. Cages are cleaned every day: in fact, together with natural waste, the current also carries a lot of waste, which must be removed as soon as possible to allow the trout in the cage to remain in the best possible conditions. Subsequently, we proceed to recover the trout rising from the…
