PI Pregler will coordinate among the development of a GT-seq (genotyping-in-thousands by sequencing) genetic marker panel to support future YY-brown trout implementation efforts. Non-native trout species like brown trout can outcompete native New Mexico fish species. The introduction of hatchery male brown trout with YY genotypes to natural populations can shift sex ratios with the eventual goal of decreasing & eradicating non-native brown trout populations in locations where recovery of native species is needed. The developed genetic panel will be used to determine the sex ratio in natural populations to assess the progress of such interventions. This project is supported and funded by New Mexico Department of Game of Fish and is a collaborative effort among three genetics labs: (1) USFWS Abernathy Fish Technology Center (Seattle, WA), (2) Floragenex (Beaverton, OR) and (3) GT-Seek (Twin Falls, ID).
