The dog days of high summer have hit the Central Europe, with temperatures ranging above 30°C. The game fish are overcome with a strange torpor. Some trout fishing is still possible, mainly on the tailwaters where the big dams keep water temperature down, but this is compressed to a short period around dawn and dusk.
On the other hand an excellent sport can be had fishing for coarse fish, such as perch, pike or asp. These are very active at this period, feeding on this season fry.
Here is a sample of summer fry imitations from a swap run by my good mate Karel Stýblo on Czech server www.mrk.cz.
