Abstract

A recent publication about balanced harvesting (Froese et al., ICES Journal of Marine Science; doi:10.1093/icesjms/fsv122) contains several erroneous
statements about size-spectrum models. We refute the statements by showing that the assumptions pertaining to size-spectrum models discussed
by Froese et al. are realistic and consistent. We further show that the assumption about density-dependence being described by a stock
recruitment relationship is responsible for determining whether a peak in the cohort biomass of a population occurs late or early in life. Finally,
we argue that there is indeed a constructive role for a wide suite of ecosystem models to evaluate fishing strategies in an ecosystem context
