The fifth annual Berrima Village Carpathon starts in two days time and some advice on fishing never goes astray, for competitors and participants alike.

Bowral Field and Stream owner Craig Golding said the key to catching carp was patience and fresh bait.

He has fished all his life and said you don't have to be an expert to catch carp.

"Use fresh bread and corn kernels, burley up to attract the fish upstream," Craig said.

"Carp are attracted by the scent of corn, I think it's the fat that attracts them."

He said small hooks will work best and suggested using the smallest sinkers.

Mr Golding said the best places on the river to fish for carp would be out of the main current, in the back waters and eddies.

The current weather forecast for Friday to Sunday is in the low 20s with chances of rain and storms.

While it is easier to catch carp on a warmer day, there are still ways to attract the fish when the weather isn't optimal.

"The carp are more active on the warmer days, you've got to be more persistent when it's cooler, use the bread and corn as burley."

Carp are bottom-dwellers so the bread and corn will work in two ways.

"The corn will sink to the bottom and the bread floats on the top."

The Carpathon is a family-friendly event and Mr Golding said fishing is great sport for the kids.

"There are no spiky bits on carp to hurt kids and they're a lot of fun to catch, anyone can do it."

Each month Field and Stream run an in-store Carp Competition where the longest carp to come in will win the fisherman (or woman) a $30 voucher.

The Carpathon starts Friday in Berrima and organiser Andrew Hearn believes it will be the biggest one yet.

Anglers can register at Andrew Hearn Real Estate, next to the Berrima General Store.

Registration fees are $10 for children, $15 for adults and $25 for a family.
