Description

Drs. Stu Ludsin and Libby Marschall have two new publications on percids out this spring.

"Mixed-stock analysis using Rapture genotyping to evaluate stock-specific exploitation of a walleye population despite weak genetic structure," was published with AEL alumnus Alex Chen; it will appear in the May edition of Evolutionary Applications. This study "provides important stock contribution estimates for Lake Erie fishery management and demonstrates the utility of genomic data to facilitate mixed-stock analysis in exploited fish populations have weak population structure or limited existing genetic resources."

Euclide, P.T., T. MacDougall, J.M. Robinson, M.D. Faust, C.C. Wilson, K.Y. Chen, E.A. Marschall, W. Larson, and S. Ludsin. 2021. Mixed-stock analysis using Rapture genotyping to evaluate stock-specific exploitation of a walleye population despite weak genetic structure. Evolutionary Applications. 14(5): 1403-1420. doi.org/10.1111/eva.13209

"Ecosystem change as a driver of fish recruitment dynamics: A case study of two Lake Erie yellow perch populations," was published with AEL alums Ben Marcek and Troy Farmer; it will appear in the June edition of Freshwater Biology. This study "demonstrates that ecosystem change can cause the relationships between environmental conditions and population processes...of aquatic organisms to vary through time and space."
