Stomach Pump by Feather Craft enables direct observation of a fish’s diet by rinsing water into the fish’s throat and drawing it back through the pump to reveal what has been eaten. This targeted, non-invasive approach avoids jamming the instrument into the stomach, reducing stress on the fish and speeding up sample collection. By cycling rinse and suction, you can inspect recent meals without disassembly or guesswork, making it easier to document feeding behavior, verify stomach contents, and compare across specimens with consistency. The tool is designed for practical field and lab use, delivering reliable results in a compact package.
