Biological data were collected from five different fisheries that target scup and from one fishery (springMassachusetts Division of Marine Fisheries Technical Report TR-10Technical ReportCharacterization of the Massachusetts Scup (Stenotomus chrysopể} Fish Characterization of the Massachusetts Scup ( Stenotomus chrysops) Fisheries eafood dealers that process scup caught from local fishermen. Data collected were used to characterize landings and discaids by length, age and ratios of discards-to-landings for each fishery. Length frequency distributions and age keys were constructed for both landed and discarded catches of scup. Characterization of the Massachusetts Scup ( Stenotomus chrysops) Fisheries Age data analyses indicated landings in each fishery were comprised mainly of age-3 and age-4 scup. whereas the majority of discards were comprised ofCharacterization of the Massachusetts Scup ( Stenotomus chrysops) Fisheries
