The dodgy net, probably intended for eels, was the gruesome discovery on the Sibsey Trader drain, three miles from the centre of Boston, Lincolnshire.
Not only did the net omit a guard to prevent otters entering it and becoming trapped, it also appeared during Close Season for eel fishing, which runs until April 1.
Environment Agency biodiversity officer Phil Smith said: ‘The Police have been informed of this illegal fishing activity and if investigations lead to finding who set the net, a prosecution will follow.
‘The eel population is declining so it is vital that eel netsman respect the Close Season to ensure that fishing practices are sustainable. In this instance, an otter, a protected species, has also suffered as a result of the illegal activity.’
