Common carp has been farmed in Central European ponds for over 1,000 years, and traditional extensive culture can provide good welfare while intensive systems raise concerns.
Traditional Czech and Polish extensive carp pond culture provides good welfare conditions through low densities, natural feeding, and extensive habitat. The welfare crunch points are autumn harvest, when fish are crowded into harvest pits in declining oxygen conditions, and subsequent live transport and sale. Christmas market live carp sales - where fish are kept in small tanks or buckets for days before sale and home slaughter - raise significant welfare concerns that are increasingly scrutinised by welfare organisations across Central Europe. Reducing harvest crowding time, improving transport water quality, and developing pre-slaughter stunning adoption are the key welfare improvement priorities.
