FISHING should be banned in almost a third of UK waters to protect the marine environment and save threatened fish species, according to a major report today.

Sir Tom Blundell, chairman of the Royal Commission on Environmental Pollution, said the sea should be treated like an endangered land habitat.

"We need to take positive steps to allow the environment to recover," he said.

"Marine reserves should be created to protect 30% of the UK's seas from fishing.

"Intervention on this scale is necessary to break the present cycle of unrealistic quotas and diminishing fish populations."
