"Jordi Grimalt, an investigator at CSIC, says that the catfish contains alarming levels of mercury, which is accumulated in its organism. He affirms that “if an animal eats the contaminated catfish fishmeal, it will also accumulate that mercury. When a person eats that animal, the same will also occur.”"

“When we reach five tonnes, we'll send them to Romania. To produce fishmeal and to eat. Over there its a very highly regarded-regarded fish to eat and sending a greater quantity is cheaper for us,” said Valentin Ivanov, brother of the company's owner and the man in charge of the catfish capture."
