Anglers who use their fishing lures to entice pikes have been urged to help protect the population of the species.
Broads Angling Strategy Group (BASG) has expressed its concerns over the plight of pikes after Environment Agency (EA) officials found three dead fish in the northern Oulton Broad in Suffolk.
BASG chairman John Currie said that although the reasons behind the deaths of the fish remained elusive, anglers should be careful when fishing for the species.
"I would urge all anglers to help us protect pike stocks by ensuring they use the correct handling techniques and proper equipment at all times when pike fishing," he said.
The EA claimed it was working closely with Mr Currie's organisation to examine various causes that may be influencing the current levels of pike in the area.
One of the three pikes found weighed more than 30lbs.
Last week, the Angling Trust discovered that the EA had known of the reasons for low stocks of salmon on the River Teign but failed to implement measures to rectify the problem.
