State and role of active conservation of barbel Barbus barbus in Poland
Barbel Barbus barbus is a highly valued target of recreational fisheries. Due to environmental degradation and growing angler pressure, its abundance has decreased in many rivers. In response to this, active protection strategies are being developed by scientists and the Polish Anglers Association. Methods of breeding in captivity have been developed for restocking purposes. Production and release have increased from 19 600 summer fry and 692 adult fish in 1998 to 7000 summer and 32 000 autumn juveniles, and 3150 two year‐old fish in 2002. The preservation of genetic diversity is a major challenge in these enhancement programmes.
