#' @title Growth increment data for West Bearskin Lake, MN, Smallmouth Bass.
#'
#' @description Growth data from Smallmouth Bass (\emph{Micropterus dolomieu}) captured in West Bearskin Lake, MN. Five samples were collected over three years (1988-1990) with two gears (fall -- trapnets, spring -- electrofishing).
