 Called crawfish in the US, they are freshwater crustaceans related to lobsters, and there are two main species in UK - the native white-clawed crayfish (_Austropotamobius pallipes_), and the non-native American Signal crayfish (_Pacifastacus leniusculus)_, which was introduced to Britain in the 1970s via dedicated farms, and subsequently escaped. There are a few other introduced species but they are not very widespread. Called crawfish in the US, they are freshwater crustaceans related to lobsters, and there are two main species in UK - the native white-clawed crayfish (_Austropotamobius pallipes_), and the non-native American Signal crayfish (_Pacifastacus leniusculus)_, which was introduced to Britain in the 1970s via dedicated farms, and subsequently escaped.

 First - getting [food from the wild](/wild/wild_food) is always a good idea from an environmental perspective (unless we deplete the resource – but this isn't an issue here, as we'll see later). Wild food requires no pesticides, fertilisers, hormones or genetic modification - in fact, no ecological interference at all. First - getting [food from the wild](/wild/wild_food) is always a good idea from an environmental perspective (unless we deplete the resource – but this isn't an issue here, as we'll see later).
