Its been well documented for many years now, the enormous catfish invasion of the Rio Ebro (After they were introduced there by people) and the damage that they can do to the endemic wildlife…But, I didn’t know that they were down here in Andalucia in such huge numbers and in the Guadalquivir which means that pretty soon thye will be in the Doñana National Park in huge numbers….
This video says it all really….

What I don’t understand is that the human race has proven time and time again that it is capable of trapping and hunting a species to extiction…. So why not trap and hunt this species to near or total extinction????
