The study area in the Susquehanna River basin, Pennsylvania, where flathead catfish were collected for dietary analysis. Shapes denote collection methods: diamonds represent highÂ-frequency electrofishing, triangles represent hoop nets, circles represent low-frequency eiectrofishing and the square represents the fish lift at the Conowingo Dam.
To determine what the flathead catfish were eating, researchers collected 576 of them over two years, with 241 individuals having recoverable stomach contents. The researchers extracted DNA from those contents and identified prey tissues.
