(Redirected from Cull)

'Culling' is the 'selection' of surplus animals from an animal population. In a wild population the selection is often done by killing the animal immediately. In a domestic situation the culling process involves selection and the selling of surplus stock. The selection may be done to improve breeding stock, for example for improved production of eggs or milk, or simply to control the group's population for the benefit of the environment and other species.
Culling for population control is common in wildlife management, particularly on African game farms and in Australia in national parks. In the case of very large animals such as elephants, adults are often targeted. Their orphaned young, easily captured and transported, are then relocated. Without proper elephant socialization, young male elephants are believed to become unruly and dangerous to other elephants, wildlife and humans. Culling is controversial in many African countries, but reintroduction of the practice has been recommended in recent years for use at the Kruger National Park in South Africa, which has experienced a swell in its elephant population since culling was banned in 1995.^[1]
In a fishing tournaments, culling refers to releasing smaller fish that won't be used to count towards an angler's total weight. For instance, if an angler is allowed to weigh in only 4 fish, he might keep his first four 2 pound fish in the livewell until he starts to catch bigger fish. As he catches bigger fish, he can release (or cull) the smaller fish.
