The paper presents a machine learning method to estimate fish size classes from photos of anglers holding fish, achieving ~50% accuracy with limited data.

The paper assesses pikeperch stocks across Europe, finding some depleted and others recovering, highlighting the need for better data and management.

This study uses high-resolution app data to show increased recreational fishing effort in Europe during and after COVID-19 lockdowns, with effort remaining elevated by the end of 2021.

This study shows recreational fishing significantly slows recovery of predatory fish species in a lake after a commercial fishing ban, while non-target species recover rapidly.
