Excited to share my latest work! We found that winter flounder are not recovering, and may even be declining further despite protections from fishing. They also seem to be failing to adapt their behavior to environmental conditions. 🧪🦑🐟 OA link: academic.oup.com/tafs/advance...

Knowing several of the NOAA fisheries scientists who model and expertly endeavor to inform decision makers on the ~500 commercial stocks, I find it hard to believe the science is “ignored” as this article claims. They also site some of the older studies (c. 2012) which have been refuted or updated.

Great paper! 🎣 Fisheries science is sometimes skeptical of extinction risk b/c of the gap between overfishing and extinction risk thresholds 🚨 BUT this paper totally aligns with theory: small range size, low growth rate, and overfishing are a perfect storm for conservation risk 🦑🧪🌏 #MarineEcology
