Some professional hunters work in the private sector or for government agencies and manage species that are considered overabundant,[1][2] others are self-employed and make a living by selling hides and meat,[3] while still others guide clients on big-game hunts.
[4] In Australia several million kangaroos are shot each year by licensed professional hunters in population control programmes, with both their meat and hides sold.
These hunters focused on species which gathered in large numbers for breeding, feeding, or migration and were organized into factory-like groups that would systematically depopulate an area of any valuable wildlife over a short period of time.
The animals which were hunted included bison, deer, ducks and other waterfowl, geese, pigeons and many other birds, seals and walruses, fish, river mussels, and clams.
The extermination of several species and the threatened loss of others caused popular legislation effectively prohibiting this form of commercial hunting in the United States.
