#' Unfished

#' Levels of the stock, parameters, or derived quantities prior to the
#' advent of industrialized fishing, i.e., can include native exploitation.

#' \item{Rationale}{Across the U.S. assessment documents that were analyzed,
#' there is a fairly equal split between the term unfished and equilibrium
#' with lower usage of virgin. The equal split of unfished and equilibrium
#' could be, in part, because it is common for the terms to appear together,
#' i.e., unfished equilibrium. The term initial was not included in the search
#' because it occurred in the documents in contexts not related to the time
#' period before industrialized fishing. For example, text surrounding the topic
#'  of initial parameter values is common in stock assessment documents.
#' Equilibrium conditions can occur at any point in time throughout the time series
#' as long as the stock is experiencing equal mortality and growth, and thus, the point
#' in time when equilibrium conditions are thought to exist because fishing at an
#' industrial-wide scale had yet to alter the stock should be referred to as unfished
#' rather than equilibrium.}
