3. Setup Instructions
The Naroote Fly Fishing Stomach Pump comes in two main parts: the pump bulb with the main tube and a separate extension tube. Assembly is straightforward:
- Ensure both the pump unit and the extension tube are clean before first use.
- If desired, gently insert the narrower end of the extension tube into the open end of the main pump tube. It should fit snugly.
- The pump can be used with or without the extension tube, depending on the size of the fish and the desired reach.

4. Operating Instructions
Follow these steps to safely and effectively use the stomach pump:
- Prepare the Fish: Gently hold the fish, ensuring it is calm and secure. Minimize stress to the fish.
- Lubricate the Tube: Dip the end of the pump tube (with or without extension) into water to lubricate it. This makes insertion smoother and safer for the fish.
- Insert the Tube: Carefully and slowly insert the lubricated tube into the fish's mouth and down into its stomach. Do not force the tube. The depth of insertion will depend on the fish's size.
- Operate the Pump: Once the tube is in place, gently squeeze and release the silicone bulb several times. This action creates suction, drawing stomach contents into the tube.
- Extract Contents: Slowly withdraw the tube from the fish's mouth. The stomach contents will be visible within the clear tube.
- Release the Fish: Immediately and gently release the fish back into the water.
- Examine Contents: Observe the contents in the tube to identify what the fish has been feeding on.

5. Maintenance
Proper maintenance ensures the longevity and hygiene of your stomach pump:
- Cleaning: After each use, thoroughly rinse the pump and tube with clean water. Use a mild soap if necessary, ensuring all soap residue is removed.
- Drying: Allow all components to air dry completely before storage to prevent mold or mildew.
- Storage: Store the pump in a clean, dry place, away from direct sunlight and extreme temperatures.
- Inspection: Periodically inspect the silicone bulb and plastic tube for any signs of wear, cracks, or damage. Replace if necessary.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No contents extracted | Tube not deep enough; insufficient suction; fish stomach empty. | Gently re-insert tube deeper; ensure bulb is fully squeezed and released; try on another fish. |
| Difficulty inserting tube | Tube not lubricated; fish resisting. | Ensure tube is well-lubricated with water; handle fish more gently to reduce stress. |
| Tube appears damaged | Wear and tear; improper storage. | Discontinue use and replace the damaged component or entire pump. |
