Tests were made on largemouth bass (Micropterus salmoides) in the laboratory and in the field at Lake Braunig, Texas, to determine the effectiveness of using a 3% hydrogen peroxide solution for removing stomach contents from live fish. The solution was injected into the stomach via the esophagus with a 15‐ml plastic syringe having a 30‐cm extension of polyethylene tubing with an outside diameter of 5 mm. Efficiency varied with prey—87% for goldfish (Carassius auratus), 94% for shad (Dorosoma spp.), and 83% for sunfish (Lepomis spp.) and tilapia (Tilapia spp.) combined. No mortality was observed.
