Claria – also known as African catfish – is a big, tasty, and above all resilient fish, and Cuba has begun farming it to improve diets there. But if they get off the farms, claria are notorious for devouring anything in their paths, WLRN reports.
But that happy scene was also an environmental alert. Claria are an invasive species in Cuba. They’re supposed to be confined to aquaculture fisheries, where they’re bred for food. Outside those farms – as these claria obviously were – they’re notorious for devouring anything in their paths.“If claria gets released outside their controlled conditions they can be a serious problem,” said María Araujo, a marine biologist with Cuba’s Science, Technology and Environment Ministry.
Claria – also known as African catfish – is a big, tasty, and above all resilient fish. It breeds abundantly and cheaply. But now that Cuba has decided to make claria a solution to its economic crisis, can it contain the catfish’s ecological threat?“When you’re dealing with a food crisis, farming fish is a good solution," says Martin Grosell, a fish and environment expert at the University of Miami’s“Does it come without any risks? No, it does not.
Cuba native Martin Arostegui discovered that six years ago on his first fishing trip back to the island since leaving as a youth. By now most Cubans are aware of that. So the government produced a video game four years ago – called"Super Claria" – to improve fish's image. It portrays the omnivorous catfish as an environmental superhero that eats up trash in lakes and rivers.
