Illegal fishing nets containing 25 eels have been seized by the Environment Agency after a tip-off.
Officers found illegal nets in the sewer containing 25 eels
A member of the public called the agency after spotting suspicious nets in Jurys Gap sewer, near Camber.
Jon Whitmore, fisheries team leader, said officers found two unlicensed fyke nets, traditionally used to catch eels, at the site on Wednesday.
The illegal equipment was seized using powers under the Salmon and Freshwater Fisheries Act.
"Our officers are patrolling hotspots on a regular basis, and anyone found fishing using illegal nets can face arrest, seizure of equipment, prosecution and fines of up to £2,500," said Mr Whitmore.
The agency had also intervened in four other cases of illegal fishing in Kent in the past two months after receiving alerts from the public, he added.
He said: "The information we receive from the public is invaluable.
"The intelligence they provide helps us protect endangered fish populations, like the eel, from further decline."
According to the agency, eels are still "a popular fish for the table".
