Summary

Abstract (from http://www.tandfonline.com/doi/full/10.1080/02755947.2014.943860#.VJhyqUACo): Invasive Rainbow Smelt Osmerus mordax have been associated with reductions in Walleye Sander vitreusrecruitment, and predation by adult smelt on age-0 Walleyes has been identified as one of the potential mechanisms contributing to recruitment failure. Predation effects could be mitigated by stocking Walleye fingerlings based on smelt and Walleye morphometric relationships. By combining 0.95 quantile regression of smelt gape size on TL and 0.05 quantile regression of Walleye body depth on TL, we constructed a stocking tool to determine the appropriate size to stock Walleye fingerlings in lakes invaded by smelt such that few Walleyes are vulnerable [...]
