Surge in octopus numbers leads to 'record £500k catch'

Marine researchers have said the mass numbers of octopus in waters around Devon and Cornwall could be "here to stay".

The Marine Biological Association's (MBA) latest study of the ongoing octopus bloom, the largest surge in 75 years, showed evidence of the invasive species' successful breeding in UK waters.

The fight to stop animals dying in fishing nets

Environmental groups have renewed calls for the government to do more to prevent the deaths of thousands of dolphins, whales and seabirds accidentally caught in fishing nets in UK waters.

Known as bycatch a new report estimates that tens of thousands of protected seabirds, more than 1,000 porpoises and dolphins and dozens of whales are dying in this way each year.

A 100m (328ft) cordon was swiftly removed after the discovery of a "bomb-shaped object" in Plymouth on Monday.

Devon and Cornwall Police were notified at about 12:30 BST to a report of the discovery of "an unknown device" by contractors at Colesdown Hill, near Elburton, in Plymouth.

A pilot project in Devon inspired by a 100-year-old idea aims to store renewable energy.

Those behind the high density hydro demonstrator scheme near Plymouth say the technology can "turn small hills into giant batteries", as part of the transition away from fossil fuels.
