Tail Fan Necrosis syndrome in decapod crustaceans: A review
Abstract Lobsters and crayfish in Australasia can develop a condition known as Tail Fan Necrosis (TFN syndrome). Many attempts have been made to find a primary pathogen or link the syndrome to commercial activities, but a solution remains elusive. TFN syndrome is a ‘wicked problem’, a problem difficult or impossible to solve because of incomplete and ...
