|---|---|---|---|
| 1 | Rapeseed cake as affordable groundbait | One cake costs about $0.45. Traditionally pressed rapeseed cake retains natural oil, has a firm texture, and breaks down slowly. | Keeps a baited area active longer and reduces the need to rebait. |
| 2 | Rapeseed cake vs. rapeseed meal | Rapeseed cake: screw-pressed, about 5% residual oil, rich roasted aroma, firm cake form. Rapeseed meal: solvent-extracted, about 1% residual oil, powdery texture, lighter aroma. | Choose rapeseed cake, not rapeseed meal, for groundbait. |

| 4 | Three-step bait preparation | Soak: crush and soak for 1–2 hours. Dry roast: roast over low heat with no oil. Ferment: add distillers yeast and brown sugar, then seal for 2–3 days. | Makes the bait softer and more aromatic for bait balls, groundbait, carp, and grass carp fishing. |
| 5 | Three ways to use it | Groundbait: break it up and toss it in. Method feeder/spod: crush, mix with base bait and cornmeal, then form balls. With fermented corn: combine natural aroma with a sour note. | One ingredient can be used in several ways depending on your fishing method and target species. |
| 6 | Comparison with commercial groundbait | A 1–2 lb rapeseed cake costs about $0.45. A 500 g bag of commercial groundbait costs about $4.47–$7.45.
