Sexual dimorphism occurs in summer flounder with females growing faster than males and females may experience a lower natural mortality rate.  Sex structured assessment models have been developed for other fishes with sexually dimorphic characteristics to more appropriately account for the population dynamics of those species.   Assessment scientists would like to develop a sex-structured model, but some prerequisite data are currently unavailable such as the sex of fish landed in the commercial and recreational fisheries.  In 2010 and 2011, sex, age, and length data were collected from the for-hire recreational fishery (n=6,494) and commercial fishery (n-11,090) from Massachusets to Virginia.  Results will be presented on the sex, length, and age structure of landed summer flounder in time and space for both fisheries.
