The Crayfish Question

It’s been nearly 50 years since invasive American Signal Crayfish were introduced to the UK, and we still haven’t figured out how to get rid of them. Hugh Fearnley-Whittingstall joins Sheila Dillon to meet a man who believes the way to control their spread is to get more people eating them — but not everyone’s convinced. These crustaceans are so invasive that ecologists worry encouraging consumption could lead to further spread. Meanwhile, in parts of the Southern US, crayfish are a beloved delicacy. Sheila heads to a crayfish boil in London to see how that tradition is being recreated here.
