Stuart (2009) Yatco Lagoon, Murray River, South Australia (~346 ha over two lagoons) N/A (see considerations’) Discusses physical control methods (e.g. screens, wetting/drying, traps) Hydrological scenarios were only related to fish passage and management of Carp screens in low and medium flows; removal of Carp screens when high flow events occur was also suggested Conceptual model of Carp life history in Yatco potential control strategies for each of the species’ life stages Potential risks and benefits for native flora and fauna emphasis on Carp control rather than total eradication. Two key recommendations: minimise the number of and subadult Carp entering and exiting the wetland system minimise the damage to wetland values by adult Carp. Three main strategies were implemented to achieve these recommendations: screens to exclude adult and subadult Carp (<250 mm TL) in low to moderate flows; removal of screens in periods of high flow introduction of wetting and drying schemes harvesting of Carp aggregations at regulators using William’s Carp separation cage.
