A cura del team dei ricercatori Life TROTA
Nella seconda metà del 2017 sono proseguite le attività del progetto Life+ TROTA e sono state effettuate le uscite necessarie a completare le azioni di eradicazione.
I dati raccolti sul campo permetteranno di conoscere l'esito della rimozione delle trote atlantiche aliene, ma anche di approfondire le relazioni ecologiche intra e interspecifiche di alcune altre specie ittiche, quale ad esempio lo scazzone Cottus gobio. Inoltre, presso l’impianto ittiogenico di Cantiano è terminato il periodo di quarantena e sono stati...

The fossil remains of fishes dating back 14 thousand years ago were found in a cave in Calabria and the DNA of the "Flintstones" Trout was sequenced thanks to a study coordinated by Professor Vincenzo Caputo Barucchi, University of Marche and partner of the Life+ Trout project.
The study helped to reconstruct the genetic changes of these fishes that once lived in the Mediterranean Sea.
"We have analyzed the DNA of trout samples from the late Pleistocene - said prof. Barucchi to ANSA agency - in a time of...

The XVI Conference of the Italian Association of Freshwater Ichthyologists (AIIAD) was held in Popoli (PE) from 21 to 23 October. During the meeting, the results from the eradication activities carried out during the Life+ Trout project were presented.
The main topic of the conference, which gathered all main experts in Italy, was about "the management of freshwater fishes from a conservation perspective": an issue perfectly in line with the objectives of the European project which specifically aims to safeguard a species considered vulnerable at the European level and strongly threatened in Italy...

During the first half of 2016 the activities of the Life + TROUT project continued including several different concrete actions, such as obtaining fertilized eggs, and restocking in the targeted sites. Also, the flow of water courses involved in the reintroduction was monitored, thus enabling the development of the first model for the estimation of environmental flow suitable for the survival of macrostigma trout.
Specifically, these are the main points of the activities implemented in recent months:
Action C2. ...

The concrete activities of macrostigma trout conservation are still ongoing, thanks to several researches in the field carried out by project partners. In fact, between the first and second project years 486 wild trout were sampled. These were photographed, marked with different colored elastomers (according to the basin of origin) and fitted with a microchip with an individual code.
Each specimen was subjected to genetic analysis and placed in a 500-...

In the second half of 2015, both the concrete conservation actions and the dissemination activities of Life + TROUT project continued involving not only the anglers's associations, but also the scientific stakeholders.
In particular, the main actions carried on in recent months were:
- Capture and selection of pure wild broodstock, as part of the C2 conservation action. Between mid-November and early December 2015, 260 adult specimens were taken from the genetically intact populations, identified during the A2 preparatory action. Compared to 2014, about 40 specimen more were sampled in order to...

Thanks to Enalcaccia fishing and hunting association and the metropolitan city of Rome Capital a hatchery's fish for research, conservation and reproduction of autochthonous trout was born in Vallepietra, in Lazio region.
A genetic study conducted in collaboration with the University of Ancona and the University of Perugia, project partners of LIFE + Trout, showed the presence of Mediterranean trout in the Simbrivio river.
The hatchery which...

The results of Life Trout project arrived in Portugal during the XV European Congress of Ichthyology (Porto, 7-11 September 2015). The genetic and demographic characterization of the trout populations was completed and it has been possible to show the results of the quantification of the trout populations in the various examined basins. Above all, it has been possible to notice the presence of three distinct genetic stocks of Apennine native trout, respectively in the Nera, Tenna and in the basins of Chienti, Potenza and Metauro.
These results were also presented in Verbania (19 September 2015) during the...
