In addition to the fishing grounds near Szumin, Wywłóka is a mecca for Mazovian anglers from the surrounding area. From the stories of anglers we have met, pike, zander, asp and perch are the most desirable fish in these fishing grounds (although of course these are not the only fish that can be found there).
But fish are a magnet, not only for anglers who fish for them here at different times of the year, also in winter, from under the ice. There are many more people willing to fish in this fish kingdom, in the form of numerous species of waterfowl, including such ornithological rarities as corncrakes, curlews, black-tailed godwits and sandpipers.
In the vicinity of Szumin and Wywłóka, one can observe almost exemplary effects of the meandering of the Bug, which leaves behind old branches and small "lakes". These areas are subject to flooding in spring; backwaters are created that facilitate the movement of fish. That is why it is here, on the "bużyska", as the old riverbeds of the Bug are called, that you can observe many anglers trying to catch the golden crucian carp, which they call the "Japanese carp", or the tench, which likes to hide in the mud, in small, often overgrown reservoirs.
