The catfish, "a monster fish" two meters long, empties the largest swamp in Andalusia of carp and barbel

The invasive catfish species in Iznájar reservoir has led to a significant decline in local fish populations, particularly carp and barbel, with catches dropping by 76% over 17 years. The catfish, which can grow over two meters long, has disrupted the ecosystem and local fishing activities. A recent study analyzed fishing competitions and found that the average catch per participant decreased drastically. Illegal fishing practices continue to exacerbate the problem, as some individuals target catfish for sport. Local fishing associations are attempting to manage the catfish population, but resources are limited, and complete eradication is deemed unrealistic. The catfish's spread poses a threat to traditional fishing and local ecosystems.
