He The center of La Pedriza is located in the area of the same namenext to the paved path that connects to Canto Cochino via the Collado de Quebrantaherraduras. It is located two kilometers from the city center, in the municipality of Manzanares El Real.
The common trout is a euryphagic species, because its nutritional spectrum is broad. Its nutritional nature is characterized by opportunism and it can adapt extremely easily to changes in food availability. It is considered by the IUCN to be one of the 100 of the world’s most harmful invasive alien species.
After the recovery of the trout
The Community of Madrid has started a project for the recovery of trout in the Sierra de Guadarrama National Park. The Minister of Environment, Agriculture and the Interior, Carlos Novillo, presented it today during the inauguration of the new aquarium at the La Pedriza Visitor Center in Manzanares El Real.
This informative installation has a capacity of 75 cubic meters in two separate vessels. One contains endemic species typical of high mountain rivers; the other, non-native species typical of reservoirs, such as carp, crucian carp, royal carp, tench, black bass and gobies, among others. Admission is free and so is the schedule Information can be consulted on the institution’s website.
The initiative includes the design and management strategy of a network of sport fishing scenarios as a tool for the socio-economic development of the area, linked to the respectful use of resources and nature. “A practice that is exploited in other areas and that generates jobs and has positive effects on the conservation of this species,” the advisor emphasized.
The trout (Salmo trutta) is a salmonid classified as vincurable in the Red Book of Spanish Vertebrates. It lives in fast, cold water and is therefore a good indicator of the good ecological status of mountain rivers. It is threatened by genetic contamination originating from repopulation specimens from fish farms of Central European and Scandinavian origin.
Agriculture and the Interior have started the construction of a breeding bank in the municipality of Rascafría. The works started last December, expected at the end of this year starts its activity and the first trout can be won.
For Novillo “this is infrastructure will play a fundamental role in the conservation of the speciesbecause it will prioritize the genetic quality of the parents and therefore of the specimens that are subsequently released into the rivers.”
About 10,000 fertile eggs will be produced that can be reintroduced into the rivers. fertilized eggs or as young (between 0 and 5 months) together with the surpluses from this installation. The breeding bank and the new aquarium have an investment of more than 300,000 euros, from European funds.
