Geographical spread of bacterial and fungal diseases of crustaceans.
The author discusses the way in which bacterial and fungal diseases of crustaceans can be and have been transmitted via commercial movements of stocks. Two classic examples of such diseases are presented, namely gaffkaemia (a bacterial disease of marine lobsters) and crayfish plague (a fungal disease of freshwater crayfish). In both cases, there is ample evidence that much of the disease spread can be linked to the commercial movement of infected animals caught from infected wild stocks and transported over large distances for wholesale and retail. In the case of crayfish plague, much of the relentless spread of this disease through Europe for nearly 140 years can also be liked to the movement of contaminated fishing equipment without disinfection.
