摘要
This paper describes the crayfish plague situation in Norway as at October 1991 and describes the spread within and between watersheds. Four watersheds are so far affected: the Glomma, the Store Le, the Halden and the Veksa/Vrangselva. The last was affected during 1971-74 whereas in the others the disease occurred in the period 1987-1989. In the Veksa/Vrangselva watercourse a dense crayfish population has been re-established due to restocking. In addition, the paper describes the management strategies implemented by the authorities in order to reduce the risk of spreading the disease. The attempts to re-establish extinct and protect threatened populations are also described
