Description:The summer flounder or fluke (Paralichthys dentatus) supports the most biologically and economically important commercial and recreational flatfish fisheries of the U.S. Atlantic coast, ranging from Massachusetts to North Carolina. Three previous papers recounted how fishing mortality had stabilized by 2017 at its lowest level in over 40 years, with stock biomass near its highest since the comprehensive stock assessments began in the mid-1970s. This sequence of stock decline to near collapse and subsequent successful rebuilding had a significant effect on the observed and estimated biological characteristics of the population. It is widely expressed that northwest Atlantic Ocean temperatures have rapidly increased over this same period and likely have a range of impacts on marine populations (Pershing et al. 2019). In this work, the assessment results and biological and environmental information associated with the stock are updated through 2022, and some exploratory analyses are conducted to quantify significant drivers of summer flounder population dynamics, all with the goal of providing useful information and direction for future stock assessments.
