One of the country's senior police officials has backed calls for more to be done to tackle reports of poaching and fish theft.
Simon Prince, Chief Constable of Dyfed Powys and the national policing lead for wildlife and rural crime, has thrown his weight behind evidence presented by the Angling Trust.
Some of the evidence centred around an incident which saw John Anderson, a bailiff for Burton Mutual Angling Club, threatened with a knife earlier this year after trying to tackle poachers.
The Association of Chief Police Officers (ACPO) will now ensure that all chief officers in England will receive training about poaching and fish theft, and pass this on to their operational staff.
Chief Constable Prince said: "As fish poaching can happen at any time and anywhere, I agree that there needs to be a greater awareness within the police service of the legislation that can be used to combat the problem.
"I have therefore caused a briefing note to be created and distributed to all chief officers to be cascaded down to call-taking staff and operational police officers."
Angling Trust national enforcement manager Dilip Sarkar said: "This is a massive step forward, which will bring an end to what, for anglers, has been an unacceptable situation.
"We understand that the problem was caused by an omission in training and it is great that this will finally be addressed."
In January, Mr Anderson was pushed to the floor by poachers after he confronted them leaving Branston Water Park with a fish. He spent a day on a spinal board at Burton's Queen's Hospital but was not seriously hurt.
It is believed the two poachers were of Eastern European appearance and may not have realised it is illegal to take fish from waters in England.
The Angling Trust's new guidelines recommend that all fishery sites display multi-lingual signs.
