Previously deemed absent from Tasmania, European carp (Cyprinus carpio) were first discovered in Lakes Crescent and Sorell in January 1995. As a result, the Carp Management Program (CMP) was established to contain, control, and ultimately eradicate carp from the lakes. Through the development of various techniques over 12 years (1995-2007), a complete eradication of carp from Lake Crescent was achieved using an integrated approach. By using these strategies in Lake Sorell, the carp population was estimated to have been reduced to less than 50 fish by 2009. However, a spawning event which occurred in spring that year resulted in the introduction of approximately 50 000 carp. Since then the CMP has used a combination of techniques which include intensive netting, biotelemetry, electro-fishing, barriers, and traps to target these fish as they become mobile. It is estimated that there are now less than 50 fish remaining, with over 99% of the original population removed. The CMP is at a critical stage which could see the complete eradication of carp from Tasmania over the next few years, providing spawning is prevented, and favourable environmental conditions occur in Spring.
