Whole-lake fish removal – fact sheet

Abstract

A central objective of our lake restoration research was to remove invasive fish from 5 lakes of >5 ha in area to restore indigenous biodiversity. We chose a variety of lakes with dominant invasive fish species ranging from goldfish to perch and koi carp (Figure 1 and Table 1). Because of the priority accorded to Lower Karori Reservoir by end users we relaxed the original criterion of> 5 ha lake area. We fished with a variety of fishing methods (boat electrofish ing, fyke and seine netting, and feeder (pod) trapping).
