Otter death sparks appeal - report illegal fishing to protect wildlife

Police and the Environment Agency are calling on people to report suspicious activity

An otter has been killed by an illegal crayfish trap

It is an offence to disturb, injure or kill otters as they are a protected species.

Authorities are urging people to report illegal activity on the rivers after an otter – a protected species – was killed in an illegal crayfish trap.

The appeal comes from the Environment Agency and Lincolnshire Police, who are investigating and have launched a witness appeal. Trapping, injuring or killing an otter – whether deliberately or through carelessness – is a serious offence under the Wildlife and Countryside Act 1981. Offenders face an unlimited fine and up to 6 months in prison.

Environment Agency officers found the trap while carrying out routine inspections on the River Witham at Queen Elizabeth Park in Grantham.

The sad discovery comes just weeks after local volunteers reported seeing a pair of otters swimming in the same stretch of river. Their return signals just how much the river has improved in recent years.

Crayfish trapping is illegal unless consent has been granted by the Environment Agency. In Lincolnshire, only drop-nets or hand lines are allowed and these must never be left unsupervised.

The trap was illegal as it was the wrong type and had not been permitted by the Environment Agency. Plus, crayfish trapping is banned on this stretch of the Witham as only the native, endangered and protected white-clawed crayfish are present there.

The illegal trap also risked introducing crayfish plague to the area, which has potential to wipe out this protected species.

Darren Randall, fisheries officer with the Environment Agency, said:

We all want to protect our precious and threatened wildlife, like otters, water voles and native crayfish, which is why it’s so important that activities like fishing and crayfish-trapping are carried out responsibly.

This case is especially worrying because it threatens native, endangered species of crayfish, which are afforded the same protections as otters under the law.

If you see suspicious fishing or trapping activity, please report it to us on 0800 80 70 60 and help us prevent tragedies like this in the future.

DC Flint, Lincolnshire Police wildlife officer for Grantham, said:

We were notified about this incident at 3pm Thursday, and were informed that an otter was found deceased in an illegal trap.

We will be investigating this and will take appropriate action. If anyone has any information, please call us on 101 quoting incident 219 of 7 February or email me direct on

Enforcement officers from the Environment Agency routinely look out for evidence of illegal traps – but are calling on local people to report suspicions by calling the 24-hour incident hotline on 0800 80 70 60. Alternatively, reports can be made to the police by dialling 101 or online, quoting incident 219 of 7 February. You can also make an anonymous report to Crimestoppers on 0800 555 111.

Otter populations have begun to recover across the country following a drop in numbers between the 1950s and the 1980s. Their return reflects the hard work done over decades to improve habitats and water quality in our rivers, which are the healthiest they’ve been since the industrial revolution. Otters remain legally protected as their numbers are still recovering.


  • European otters have been awarded the highest level of conservation protection, having been identified as a European Protected Species under the European Habitats Directive. They are listed on the International Union for Conservation of Nature (IUCN)’s red list of threatened species.

  • Lincolnshire Police’s wildlife and rural crime unit investigates incidents of poaching, illegal hunting and offences against endangered and protected species.
