Illegal fishing (poaching) in watercourses of the Tisza River drainage in Ukraine (Transcarpathian region) was investigated focusing on the use of illegal gears and techniques. It was found that this activity is traditional and widespread in the region and is primarily practiced by low-income residents of rural communities. Fish are harvested mainly for personal consumption. The investigated illegal gears and techniques included gill nets, lift nets, screen nets, electrofishing devices, spears, and concussion. In total, 31 species were observed in poachers catches, among which the most abundant were nase, Chondrosotma nasus (L.), Carpathian barbel, Barbus carpathicus Kotlik, Tsigenopoulos, Rab et Berrebi, and chub, Squalius cephalus (L)
