Since its inception within the Inland Fisheries Service in 1995, the Carp Management Program has been successful in its objective to contain European carp in Lakes Sorell and Crescent. The data, knowledge, skills and infrastructure that have been built over this period have enabled the program to demonstrate near complete carp eradication in Lake Crescent. Estimates indicate the carp population in Lake Crescent has been reduced to less than 10 fish. Physical removal of the last remaining carp in Lake Crescent has been challenging owing to reduced catch per unit effort, which is not surprising given the dwindled population size. Contrary to the situation in Lake Crescent, the size of the lake, wetland spread and response to rainfall the eradication of carp from Lake Sorell has been even more difficult. To address both these situations the program has integrated additional approaches to assist effective removal of carp from both the lakes while preventing any recruitment.
