Leuciscus carolitertii Doadrio, 1988 |
The Northern Iberian chub, known scientifically as Squalius carolitertii, is a type of freshwater fish. It belongs to the family Cyprinidae, which includes carps and minnows. This fish lives in the rivers of Portugal and Spain. People in those countries sometimes call it bordallo, escalo, or gallego.
Its natural homes are rivers, including those that sometimes dry up. The IUCN (International Union for Conservation of Nature) says this fish is not currently in danger of disappearing.
Where the Northern Iberian Chub Lives
The Northern Iberian chub is a small fish found only in the Iberian Peninsula. This area includes Spain and Portugal. It lives in many river systems there.
You can find it in the Douro, Mondego, Lima, Minho, and Lérez river areas. Recently, this fish was also found in the upper parts of the Alberche River. This river flows into the Tagus river system in central Spain. It was also seen in the Oitavén River, which is part of the Verdugo River in northwestern Spain.
What the Northern Iberian Chub Eats
The Northern Iberian chub is an omnivorous fish. This means it eats both plants and animals. It mostly eats small creatures that live in the water.
Young Baetis spp. (a type of mayfly) are a favorite food. The chub also eats detritus, which are tiny bits of dead plants and animals.
As the fish grows older, its diet changes.
- Younger fish eat more detritus, but older fish eat less.
- The types of prey they choose change as they get older.
- Bigger fish tend to eat bigger prey.
