Genetic population structure of marine fish: mismatch between biological and fisheries management units
Abstract An essential prerequisite of a sustainable fisheries management is the matching of biologically relevant processes and management action. In fisheries management and assessment, fish stocks are the fundamental biological unit, but the reasoning for the operational management unit is often i...

Abstract An essential prerequisite of a sustainable fisheries management is the matching of biologically relevant processes and management action.
