Lake Piaseczno boasts the greatest abundance of salmonids among natural fisheries in Poland.

It is inhabited by three species of trout: the brown trout (Salmo trutta), the brook trout (Salvelinus fontinalis) and the most common and bravest, the rainbow trout (Oncorhynchus mykiss). Thanks to careful husbandry some specimens live in the lake for several years and weigh a few kilograms. The largest rainbow trout specimen caught with an artificial fly was 98 centimetres long and weighed nearly 10 kilograms! The lake contains also sea trout and lake trout, pike, perch and Baltic whitefish.
The fishery offers superb conditions for fishing with artificial lures.
Fly-anglers: trout and sea trout lake fishing with artificial flies is considered one of the most difficult methods of this beautiful sport. You will be able to try all techniques of lake fishing from the classic lake streamering through fishing with wet flies and nymph fishing to the use of fake midges and ephemerids, and, during certain seasons of the year, with dry flies.
Spinners: using sophisticated spinning kits, you can take on large fish, catching them in a most spectacular way near the surface of the lake. In the summer, you will have to guide the bait deep under water, in the thermocline, a few or even a dozen metres below surface.
