Fish of Monfragüe national park, Extremadura, Spain

This July 2015 video from the Guadalora river in Andalusia, Spain shows Tropidophoxinellus alburnoides (or: Squalius alburnoides) fish. This species lives a bit more to the north, in Extremadura, as well.

Still 13 April 2016 in Extremadura, Spain. We had arrived at Monfragüe national park. Before blogging about birds in that park, first about fish: based on a park sign, and this source.

Indigenous fish species in the park waters include the two barbel species Iberian barbel and Luciobarbus bocagei.

Also autochthonous: Iberian nase. And Iberochondrostoma lemmingii. Both species are related.

And Tropidophoxinellus alburnoides. And Squalius pyrenaicus.

All these autochthonous species mentioned here are endemic to Spain and Portugal.

This video from Spain says about itself:

20 January 2015

Brown trout (Salmo trutta), Iberian barbel (Luciobarbus bocagei) and Iberian nase (Pseudochondrotoma polylepis) ascending the vertical-slot fishway model built in Hydraulics Laboratory (Centre for studies and experimentation on public works, CEDEX).

Fish species of Monfragüe, introduced from elsewhere, include carp.

And Prussian carp (introduced from, originally, Asia).

And largemouth bass, pumpkinseed and black bullhead, all three from North America.

And northern pike. And zander.

And big wels catfish.

And much smaller eastern mosquitofish.
