Figure 1. – A: Map of New Zealand indicating study regions; B-D: West Coast streams and lakes sampled for returning juvenile kōaro (Galaxias brevipinnis); E: Streams sampled around Lake Wakatipu; F: Streams sampled around Lake Wānaka. Genetic samples and otolith trace element signatures were obtained from fish collected from Buckler Burn, Stony Burn, 25 Mile Creek, 12 Mile Creek, Devil's Staircase Creek and 50 Mile Creek in L. Wakatipu (Panel E), and Alpha Burn, Waterfall Creek, Camp Creek, Boundary Creek, Wharf Creek in L. Wānaka (Panel F). Larval trawling was conducted near Reese River, Dart River Greenstone River, Buckler Burn in L. Wakatipu (panel E), and Makarora River, Matukituki River, Albert Burn and Boundary Creek in L.
