The Ebro River: invaders and invaded

Although the Ebro is one of the best preserved large rivers in Europe, is also the scene of an environmental conflict between native and invasive species. To understand this conflict the reporter Pere Renom will practise kayaking on some of the wildest corners of the Ebro river. He will find naiades, a group of freshwater bivalves critically endangered. He will know the zebra mussel, an invasive species that is radically transforming the river ecosystem. He will descend to the Delta, where some native fishes such as fartet (Aphanius iberus) and samaruc (Valencia hispanica), strive to resist the invasion of the mosquito fish. And he will go to the Riba-roja reservoir for fishing catfish, a sort of “monster” that devours anything that moves near it.
