Fish smell far better than most anglers give them credit for, and understanding what actually attracts them by scent explains a lot about why certain baits and additives consistently outproduce others, particularly in conditions where sight alone doesn’t cut it.
Sweet, fruity flavours – strawberry, tutti-frutti, scopex – have become carp fishing staples for good reason, and I think they mimic the sugar content of natural food sources fish already recognise. Fishmeal-based scents work on a different principle entirely, mimicking natural prey decay that many species associate with a reliable feed source.
Where I think a lot of anglers go wrong is over-dosing bait with scent, assuming more is always better. In my experience, particularly on pressured waters, an unnaturally strong scent can put fish off rather than draw them in – I now deliberately under-dose relative to bottle instructions on hard-fished venues, and it’s produced better results than heavy dosing ever did.
Scent matters most, in my experience, when fish can’t yet see the bait – coloured water, longer range, deeper water, or low light and cold conditions where smell genuinely becomes the dominant sense. In clear, shallow water with good light, I’d put more effort into visual presentation than chasing the strongest scent on the shelf.
My practical rule of thumb: match scent strength to how much the fish are relying on smell versus sight in the conditions you’re fishing, and resist the urge to assume the strongest-smelling option is automatically the best one.
Rob Hadley grew up fishing the rivers and drains of the Norfolk Broads, and it was inevitable that pike would become his species of choice. He’s been targeting predators seriously for over 20 years – starting on dead baits, moving through live bait rigs, and eventually landing on lure fishing as his preferred method about eight years ago.
These days he fishes the Broads through winter, travels to Chew Valley Lake each spring for its outsized fish, and spends the warmer months working soft plastics on rivers across the East Midlands for perch and zander. He’s had pike to 31lb and perch to 3lb 9oz, and reckons both records are beatable on the right day with the right set-up.
At The River Bend, Rob writes the predator species guides, lure fishing technique articles, and most of the winter fishing content.
