University of Salford's Dr Stefano Mariani told London's The Mail, "This is further evidence that human over-exploitation of fish stocks has adverse and far-reaching effects. Areas with poor regulation have smaller, younger fish and, as we've now demonstrated, higher and more harmful parasite infestations. Betty is quite gruesome and does remind you of the Alien films, but it's a highly adapted and specialised animal which is very successful. Unfortunately, over-fishing upsets the balance of parasite and host and interferes with the whole eco-system." Mariani further warned, "It makes a lot of sense for protected areas to be established so we can safeguard both the quantity and the quality of the fish we eat."
