The best-known autumn pond harvest in the Karst area takes place at Olšovec in Jedovnice, this year on 7 and 8 November 2026. It’s a two-day event with Jedovnice carp for sale, fish specialities and plenty of stalls. This year’s season was opened by a smaller, privately owned pond, Dymák, on the edge of Jedovnice, which was fished on Saturday 10 October. According to the organisers, carp there cost 120 Kč per kilo (approx. €4.80 — an indicative conversion, as exchange rates fluctuate). Get there early in the morning, wear wellies and bring a bag or bucket for your fish. Dates can shift depending on water levels, though, so check before you set off.

Autumn in Jedovnice belongs to the ponds. The water is slowly let out, stalls go up along the dam, and fishermen in waders haul in the nets. The harvest is a tradition locals wouldn’t miss, and one that draws visitors from all over the region.
Olšovec: the Biggest Harvest in the Region
When: Saturday and Sunday, 7–8 November 2026.
Olšovec covers around 42 hectares and is the largest pond in the area. Jedovnice has owned it since 1931, and since 1967 it has also served as a summer recreation spot. The first record of a harvest here dates from 1900, though fishing in Jedovnice is mentioned as far back as 1741.
What to expect:
- Jedovnice carp for sale, carrying the Moravian Karst Regional Product label,
- live fish right on the dam: grass carp, silver carp and roach,
- fish specialities and food stalls,
- you can watch the harvest from the bastion and see the fishermen at work up close.
In past years the harvest began at 7:30. The organiser hasn’t yet published exact times for this year, so keep an eye on olsovec.cz. For enquiries, contact the Olšovec campsite (tel. 725 896 488).
Dymák: a Smaller Harvest to Start the Season
When: this year on Saturday 10 October 2026, open to the public from 8:00.
Dymák is a privately owned pond on the edge of Jedovnice, and its harvest kicks off the local season. It’s smaller and more intimate than Olšovec, but the fish you buy are every bit as fresh.
According to the organisers, prices stayed the same as in 2025:
| Fish | Price per kilo |
|---|---|
| Carp | 120 Kč (approx. €4.80) |
| Grass carp | 130 Kč (approx. €5.20) |
| Silver carp | 80 Kč (approx. €3.20) |
There are also smoked delicacies on sale, and there’s usually a fish tank for the children.
How to Do a Pond Harvest
- Go early. Most of the action happens in the morning, when the fishermen draw in the net and the fish are sorted.
- Wear wellies, or at least sturdy boots. The dam can get very muddy.
- Bring a bag, bucket or cool box. A live carp travels home best somewhere damp and cool.
- Cash comes in handy. Not all stalls take cards.
- Parking in Jedovnice is limited during the Olšovec harvest. Expect to walk a fair way.
- Check the date. Harvests depend on water levels and the weather, and if the pond can’t be drained as planned, the date is pushed back.
What to Combine with Your Trip
- From Olšovec, a nature trail leads to the Rudice Sink (Rudické propadání), where the Jedovnice Stream disappears underground.
- You can follow the red trail from Jedovnice past the ponds and into the Rakovec Valley (Rakovecké údolí). We have tips in our article The Moravian Karst without the Crowds.
- November is quiet in the Karst, and the caves run on their winter timetable with fewer tours. You’ll find opening times and prices in our guide to cave prices.
