The fish trap (
: katiska) is used to catch pike. It can be found on the porch in front of the cottage, which is located on the island in the middle of lake Peräjärvi. It is recommended to place the trap in the waters surrounding the island or under the bridge between Loppe and the abandoned farmhouse as placing it anywhere else drastically reduces the speed at which it will attract fish. Once the trap has managed to catch some fish, it can be opened by pressing F. The trap can hold up to 20 fish.
The fish can be cooked on the grill, the brick grill, the fireplace, the stove, the wood stove or even on the Satsuma's engine if it's on fire. Once eaten, the player must put the trap back in the water and wait for more fish to enter the trap.
