Trap Fishing in Finland

Fishing with traps (Finnish: katiska) is a traditional and highly effective method used in Finnish lakes and coastal waters. It’s especially popular among summer cottage owners, beginners, and those who enjoy guaranteed results with minimal effort.


“Set it and forget it”.

The katiska doesn’t require active fishing. Just place it in the water, a few hours or days later, you’ll have fresh fish ready for the table.

What Fish Can You Catch in a Katiska?

Katiska traps are especially effective in shallow, weedy waters. Common catches include:


  • Perch
  • Pike
  • Roach
  • Burbot (in winter, under the ice)
  • Ide, and baitfish in vegetated areas


Note: Valuable species like trout, whitefish, or sea trout are rarely caught in traps.

How Does a Fish Trap (Katiska) Work?

The concept is simple: fish swim in through a funnel-shaped entrance but can’t find their way out. The trap does not injure the fish. They can be kept alive and fresh in the water for days. The trap can also be used like a keep net.


Benefits of Katiska Fishing:

  • Minimal effort, maximum yield
  • Perfect for family trips and cottage use
  • Fish stay fresh and alive
  • Works in bad weather or when rod fishing fails
  • Great as a backup on a slow fishing day

True Story: An Unexpectedly Massive Catch

In 2013, a Finnish angler misplaced his trap. Four days later, when he found it, it was too heavy to pull out alone - packed with over 100 kg of roach. It took three friends to haul it out. The result? An astonishing and unforgettable haul.
