| Objective | To determine the comparative resistance of pygmy perch (Nannoperca australis) and mosquitofish (Gambusia holbrooki) to heat waves (the combined effects of heat and hypoxia). To determine the relative swimming capacity of pygmy perch and five other native small-bodied fishes of the Murray-Darling Basin. Swimming capacity is a component of a species’ resilience to localised disturbance; its capacity to ‘bounce back’ after localised reductions in abundance. To undertake a field survey of Barmah Forest wetlands to determine whether pygmy perch are present within Barmah, following strong reductions in population size during the Millennium Drought. |
