Evaluating the utility of effective breeding size estimates for monitoring sea lamprey spawning abundance

Sea lamprey (Petromyzon marinus) is an invasive species that is a significant source of mortality for populations of valued fish species across the North American Great Lakes. Large annual control programs are needed to reduce the species' impacts; however, the number of successfully spawning a...

Description
Summary:Sea lamprey (Petromyzon marinus) is an invasive species that is a significant source of mortality for populations of valued fish species across the North American Great Lakes. Large annual control programs are needed to reduce the species' impacts; however, the number of successfully spawning adults cannot currently be accurately assessed. In this study, effective breeding size (Nb) and the minimum number of spawning adults (Ns) were estimated for larval cohorts from 17 tributaries across all five Great Lakes using single nucleotide polymorphisms (SNP) genotyped via RAD‐capture sequencing. Reconstructed larval pedigrees showed substantial variability in the size and number of full‐ and half‐sibling groups, Nb (
