Anglers across Cambridgeshire are being reminded that rivers are off limits from next Sunday.
The Environment Agency is warning anyone thinking of going fishing in rivers and drains that the coarse fishing close season is in place and anyone caught breaking the rules may be prosecuted.
Fishing is still permitted on many canals and stillwaters, depending on landowner agreement.
Ian Hirst, Environment Agency team leader, said: “The river close season for coarse fishing is there for a reason.
“By preventing coarse fishing for three months, between March 15 and June 15, it allows for an uninterrupted spawning period which increases spawning success, in addition to providing wider environmental benefits.
“Environment Agency Fisheries Enforcement Officers will be carrying out regular patrols of waters during the close season and anyone found fishing illegally may face prosecution and a hefty fine.”
Anglers are also being reminded that they need a valid Environment Agency rod licence which allows them to use up to two rods.
Rod licences run from April 1 to March 31 the following year and fishing without one can lead to a fine of £2,500.
Illegal fishing should be reported to the Environment Agency’s Incident Hotline on 0800 80 70 60.
