As with all our baits the OCEAN TUNA boilies are rolled from the finest quality natural ingredients. These high protein baits are specifically designed to select larger fish. High levels of ground tuna flour combined with soluble fish proteins and attractive liquid extracts create a bait that works quickly once on the bottom. Perfect for spot fishing or short sessions. Designed to trigger a reaction, the baits have a distinctive taste and odour that fish home in on. Enriched with fish oil, these baits work equally well in summer or winter.
