Found this in the guardian this week, obviously the 30lb bit is wong???
A fish that is believed to have died out in Britain 40 years ago has been bred by scientists at Brooksby Melton College in Leicestershire, who are hoping to reintroduce it. More than 200 burbot fry have been produced in laboratory conditions that mimic British rivers. If they thrive, they will be put into the wild. Burbots, which are related to cod and were probably wiped out by pollution, like fast-flowing rivers and deep, cold lakes, and can weigh up to 30lb. Scientist Ian Wellby said: "Rivers are much cleaner now and we hope that global warming has not warmed up the rivers too much."
